First Da Vinci Robot Heart Surgery In Britain
October 23, 2012
Surgeons have carried out the first ever robotic open-heart operations in Britain at the New Cross Hospital in Wolverhampton.
Natalie Jones, of Stourbridge, 22, was the first patient to undergo this procedure to have a 3.5cm (1.3in) hole in her heart repaired. The surgery lasted nine hours.
Normal heart surgery involves cutting open the breast plate, but with the Da Vinci robotic procedure arms are inserted by making small cuts between the patient's ribs.
The robot is then remotely controlled by surgeons who are given a high definition 3D view of the heart through a sophisticated camera. Each time they move their hand 3mm, the robot arm moves just 1mm. Doctors claim the operation is safer for patients than conventional surgery.
Heart surgeon Stephen Billing said: "There is less pain and patients are able to return home to their normal activities far sooner."
NewYork-Presbyterian Hospital/Weill Cornell Medical Center expands its Robotic Thoracic Surgery Program
Posted on AARS: August 11, 2012
Thoracic surgeons at NewYork-Presbyterian Hospital/Weill Cornell Medical Center are expanding the use of robotic surgery to the treatment of lung, esophageal, mediastinal, and thymic cancers and other disorders. They are able to perform some lobectomy, esophagectomy, and thymectomy procedures using this approach.
During the robotic procedure, the surgeon sits at a console, viewing the surgical field through the robot's "vision system." The surgeon uses controls to operate the various arms and cameras of the robot, which are placed into position in the patient by surgical assistants. The surgery robot enables the surgeon to operate with greater magnification of the surgical field and more precision in the use of surgical instruments.
The FDA has granted clearance for the CorPath 200 System, a robotic system that assists heart surgeons in restoring blood flow to blocked coronary arteries.
Corindus Vascular Robotics, a Natick, MA company, announced today that the FDA has granted clearance for its CorPath 200 System. The CorPath 200 provides robotic assistance for heart surgeons that are performing percutaneous coronary interventions – which you probably know better as an angioplasty. In this surgical technique, blood flow is restored to a blocked coronary artery. This is usually accomplished by inflating a balloon in the artery, then implanting a stent to keep the artery open. There are other varieties of intervention, as well.
Although coronary angioplasties are relatively common, they pose risks to the doctor’s who perform them. When the procedure is being performed, the patient is being x-rayed, and the surgeon is exposed to the radiation as well. Although surgeons wear a lead apron during the procedure, that still leaves them exposed in other parts of their body. A recent study reported that this may be the cause of higher risk for brain tumors for those surgeons. Plus, standing for hours on end while wearing a heavy lead apron tends to lead to orthopedic problems for the surgeon.
The CorPath system gets around this problem by providing a means for the surgeon to perform an angioplasty without risking their own health. The doctor sits in a lead-lined cockpit, in a comfortable chair, and remotely controls the robotic system as it implants the balloon or stent catheters into the patient. The monitors give the surgeon the ability to control the visualization of the patient directly, and the robotic controls are incredibly precise – surgeons can move millimeter by millimeter during the procedure.....read more
Snake-like robot could perform surgery on heart or excise tumours
June 8, 2012
Researchers in the US have developed a snake-like robot which could perform surgery on the heart or excise prostate tumours.
Snakebot is an ultra-slim device which can crawl inside a small incision and perform surgery, with miniature tools attached which can be controlled by the surgeon. The technology has been developed by Howie Choset, a rambunctious roboticist who has been working on snake-like robots for decades at Carnegie Mellon University.
The device has successfully passed animal testing on pigs, and will now be used on human trials to ensure that it has the same effects. It works by making a small keyhole incision which is used to feed the snake into. The surgeon uses a remote control to guide the snake to the damaged/diseased organ where it then extends its miniature tools and gets to work.
Surgical operations are achievable thanks to the complexity and size of the robot. The head is smaller than the size of a US dime (18mm) and there are 102 joints and a camera installed which allows the robot to navigate with amazing precision.....read more

Tiny Robots Mend Broken Hearts
June 7, 2012
For cardiac patients, repair of defects often requires open-heart surgery and temporary paralysis of the organ. But a set of robotic tools developed by researchers at Boston Children’s Hospital could eventually enable surgeons to operate on the heart through small incisions while the heart continues to beat.
The use of small incisions and the insertion of robotic tools are increasingly common in many types of surgery. Such so-called minimally invasive surgery offers quicker recovery times than conventional surgery and reduced risk of infection, because the cuts in the body are much smaller. In the case of minimally invasive cardiac surgery, robotic tools have had to be delivered by catheters—smooth, flexible tubes that can carry, for example, an artery-opening stent. But because they are flexible, catheters can deliver only small amounts of force and can be difficult to position precisely.
The team at Boston Children’s Hospital instead uses curved-metal-tube robots to create a stiffer tool delivery platform inside the heart. “With standard open-heart procedures, we can pull tissue from one area to another. We can’t do that with a catheter. These robotic devices can exert some force, so they are able to do much of what a surgeon does, except they are navigating through the blood vessels,” says Pedro del Nido, a pediatric cardiac surgeon involved in the project.
The devices reach the heart through an incision in the neck that leads to the jugular vein. From there, long, narrow concentric tubes carry the surgical devices through the large blood vessels to the heart.....read more
'Heart Team' Pairs PCI and Robotic CABG
May 13, 2012
LAS VEGAS -- A surgical robot allows cardiologists and surgeons to work on the same patient with complex multivessel disease, sometimes on the same day, leading to a shorter recovery time, researchers said.At 1 month post-surgery, 85% of the 32 patients in this study reported being able to perform yard work, according to Sugam Bhatnagar, MBBS, MPH, of the University of Arizona in Tucson, and colleagues.At 1 year, those who underwent hybrid minimally invasive coronary revascularization were 16% less likely to die or experience major complications compared with similar patients undergoing open bypass repair, Bhatnagar reported here at the Society for Cardiovascular Angiography and Interventions meeting.
The hybrid procedure, with the da Vinci surgical robot system, enables cardiologists to perform percutaneous coronary intervention (PCI) and surgeons to perform CABG surgery in the same patient, often on the same day, which calls for a new way of evaluating patients.....read more
Valve Repair, Without Open Heart Surgery
May 8, 2012
Mercy now offers transcatheter aortic valve replacement (TAVR) for high-risk patient.
Mercy Heart and Vascular Hospital physicians are among only a few in the U.S. now offering the transcatheter aortic valve replacement (TAVR), an innovative procedure to replace narrowed or diseased aortic heart valves non-surgically using a catheter.
Many patients are not healthy or strong enough for traditional valve replacement surgery, which involves opening the patient’s chest and placing their heart on a bypass machine during the valve replacement. With TAVR, Mercy specialists feed a catheter through a patient’s artery in the groin to their heart and replace the aortic valve from the inside.
This innovative technology involves a bovine heart valve stitched inside a stainless steel scaffold, or stent. The Edwards SAPIEN transcatheter heart valve is crimped down onto a catheter which is then fed up through a patient’s femoral artery to the heart. A tiny balloon temporarily inflates inside the stent, setting it in place and replacing the malfunctioning valve.
Nearly 1.5 million people in the United States suffer from aortic stenosis, a progressive disease that affects the aortic valve of their hearts. Of those, approximately 250,000 suffer from severe aortic stenosis.
Patients who are interested in finding out if they’re a candidate for TAVR can contact The Center for Heart Valve Disease at Mercy Heart and Vascular Hospital at 314 251 5800
Hearts And Technology: Ongoing Innovations In Cardiology
April 27, 2012
Lori Turner, 53, was lying on a table in the electrophysiology lab at St. Francis Hospital and Medical Center, obscured by heavy equipment. Born with a rare, potentially fatal heart condition called Wolff-Parkinson-White syndrome, or WPW, the Mansfield resident was undergoing an operation that would fix the defect and end her periodic bouts of rapid heartbeat and dizziness.
Cardiologist Joseph Dell'Orfano, the doctor performing the surgery, occasionally went into the operating room to make adjustments. Most of his work, though, was conducted in a room on the other side of a large glass window filled with computers and electronics.
The operation was performed with the Epoch Robotic Magnetic Navigation system, which allows doctors to remotely steer the catheters inside the patient's body, aided by giant magnets on each side of the patient. Because the catheters in the new system are floppy, there's less chance of perforating the heart than with traditional catheters. With even more powerful magnets, the Epoch gives the operator more control, Dell'Orfano said, and is faster and more intuitive......read more
Local hospitals helping to pioneer heart procedure
Posted: April 6, 2012
A new, minimally invasive treatment is offering older patients with diseased heart valves an option when traditional open-heart surgery is too risky for them.
In November 2011, the Food and Drug Administration approved The Edwards Lifesciences' Sapien Transcatheter Heart Valve to treat age-related aortic stenosis, a condition in which calcifications build up over time on the heart's aortic valve, preventing it from opening properly.
In minimally invasive aortic valve replacement, a catheter is inserted through a small cut in the groin and threaded through the femoral artery to the heart. A balloon is inserted to open the blocked valve and then removed. The compressed artificial valve is then threaded into place over the diseased valve and expanded.
HCA Virginia is evaluating patients at Henrico Doctors' Hospital and the Levinson Heart Hospital at Chippenham Hospital and will begin performing the procedure in June.
At the University of Virginia, doctors have performed the procedure on about 70 patients as part of clinical trials and since the device was FDA-approved and became commercially available.
Sentara Heart Valve and Structural Disease Center in Norfolk is offering the procedure and has done at least five cases....read more

To Your Health: Minimally invasive options there for heart valve disease February 7, 2012 Heart disease is the leading cause of death and disability in the United States, taking the lives of more than 600,000 people annually. To help in combating this disease, February has been designated as “Heart Month,” a time to actively raise awareness of heart disease, its symptoms, its treatment and its prevention. When hearing about heart disease, many people think of coronary artery disease, or CAD, a process where the arteries that supply blood to the heart become blocked. While artery disease is the most familiar form of heart disease, diseases involving the heart’s valves are very prevalent and can be equally as dangerous. The heart has four valves that function to keep blood flowing in a forward direction. Conditions such as rheumatic fever, infection, birth defects or aging may cause a valve to become dysfunctional and can disrupt the flow of blood through the inside of the heart. This type of heart disease typically requires surgery.
Symptoms of valvular disease can include a heart murmur, fatigue, shortness of breath, swelling, racing or irregular heartbeat, decrease in exercise tolerance and dizziness. These symptoms may develop suddenly or over a period of time depending on the type of disease. The great news is significant advances in technology have led to minimally invasive approaches for performing heart valve repairs and replacements. According to the American Heart Association, approximately 5 million people are diagnosed with valvular heart disease annually and 200,000 people each year are in need of an intervention to repair or replace a valve.....read more
Methodist Hospital Buys Preclinical Vascular Robotic System from Hansen Medical February 6, 2012 The Methodist Hospital from Houston, Texas has purchased a preclinical vascular robotic system from Hansen Medical that specialises in flexible catheter robotics to conduct preclinical endovascular research.

Traditional Open vs Minimally Invasive Robot Assisted Hybrid Bypass Surgery February 3, 2012
When professor Richard Michod from the University of Arizona department of ecology and evolutionary biology learned he had three blocked heart arteries that required surgery and/or stenting to restore normal blood flow to the heart he was presented with options that included a pioneering, minimally invasive hybrid coronary artery bypass graft procedure offered by Dr. Robert Poston, UA chief of cardiovascular and thoracic surgery.
"Traditional coronary artery bypass graft", in which a full incision down the chest is made to open the ribs for access to the heart and arteries. During the surgery, the surgeon takes a segment of a healthy blood vessel from the chest, leg or arm and attaches it to the diseased artery to bypass the clogged area and create a new channel, allowing blood to flow freely again.....or...
"The hybrid approach" involving angioplasty and stenting on two arteries along with a minimally invasive, robot-assisted coronary artery bypass graft on another artery – a pioneering surgery that avoids opening the chest, relying instead on small incisions between the ribs.
The minimally invasive coronary artery bypass graft surgical approach is a recent development, and its track record is not as established as that of traditional bypass surgery.
Treatment choices differ with age, overall health, the number, location and severity of the plaque buildup in the coronary arteries, and any previous treatment the patient has had. But thanks to recent recruitment efforts at the UA, it is an option offered now on a case-by-case basis.
Poston has performed the minimally invasive, robot-assisted heart bypass surgery more than 500 times. With his expertise, the UA now is the only institution in Arizona and one of only a handful in the nation to offer the minimally invasive surgery....read more

Breakthrough cardiac surgery simulator has great commercial potential
GASPS of amazement emanated from the group of onlookers gathered inside the demonstration tent on the lawns of the Caribbean's premier tertiary institution last week as researchers switched on what could be the world's first cardiac surgery simulator.
The machine with the pulsating pig's heart was the highlight of the University of the West Indies' (UWI) 13th annual Research Days, held last Thursday and Friday. It could also be the start of great things for cardiac surgeons Drs Paul Ramphal and Daniel Coore, who invented the machine, called the UWI Cardiac Surgery Similator.
According to the two, the instrument — a combination of mechanics, computerised electronics, artificial blood, and dead animal flesh — will not only shorten the time spent on training young local surgeons, but will also make them more competitive on the international scene.
"It is difficult to spend time during the (real life) operations taking junior surgeons through the procedure. Time is of the essence in cardiac surgery," said Ramphal, who said he was tasked with the challenge of training three new cardiac surgeons in 2001.
"So the inspiration really, was how do I get my new trainees to a level so that when they reach overseas to complete their training in a high-volume centre like the UK, Canada, or the US, they will not be behind, and preferably in a more advanced position than the other trainees who were at those centres?" he said....read more
New heart treatment started at Buffalo General Hospital January 25, 2012
Buffalo General Hospital surgeons have begun offering a new cardiac procedure aimed at patients ineligible for other life-saving procedures.
The transcatheter aortic valve replacement (TAVR) procedure was recently approved by the Food and Drug Administration . The minimally-invasive procedure attaches an artificial aortic heart valve to a wire frame, which is then guided through the femoral artery by catheter to the heart. Once in place, the wire frame enlarges, which allows the new valve to pump the blood.
Buffalo General was selected as the only hospital in Western New York, and west of Albany, to perform the procedure initially A team of surgeons performed the first two procedures last week, led by Dr. Vijay Iyer, medical director of cardiology at Kaleida Health and assistant professor of medicine at the University at Buffalo School of Medicine and Biomedical Sciences.
Developed by the Edwards Lifesciences Corp. , the SAPIEN Transcatheter Aortic Valve Replacement System gives patients who had previously been deemed inoperable a viable treatment option....read more
The Amigo Robotic Surgical System
A ‘ROBO-DOC’ FIXED MY FLUTTERING HEART January 24, 2012
Not many people can claim their life may have been saved by a robot but for Patrick Flood it is no exaggeration. He became the first person in the world to have a new high-tech robotic arm perform a delicate surgical procedure to correct a potentially fatal heart defect called atrial fibrillation (AF)
The condition, where the heart’s normal rhythm suddenly becomes chaotic, is one of the biggest risk factors for a stroke. When the heart does not beat properly blood pools and thickens inside its main pumping chambers. If a clot forms it can break loose and travel to the brain causing a stroke.
Some patients need a procedure called catheter ablation. This is where a cardiologist inserts a thin, flexible tube into an artery and navigates it through the body until the tip reaches the damaged heart muscle. High-energy waves then destroy the defective tissue and restore electrical impulses to normal but the procedure is not without risks both for the patient and the doctor.
Doing it by hand requires a very high skill level if healthy tissue is not to be damaged as well. This means doctors have to “navigate” by monitoring an X-ray image. In order to protect themselves against the daily exposure to dangerous radiation they must wear a heavy and cumbersome lead apron throughout the whole procedure.
At Glenfield Hospital in Leicester cardiac specialists have introduced a revolutionary new robot-controlled device called the Amigo system.
The high-tech invention is so precise and responsive it can steer the catheter to within a millimetre of the target area deep inside the body. The doctor can sit safely in an adjacent room free from X-ray exposure.....read more
"Heart 411," a new book on heart health by two Cleveland Clinic cardiologists January 24, 2012
Can sex prevent heart disease? Can anger cause it? And what about red wine -- can we finally get an answer on whether it's good or bad for our hearts?
We can get that answer and a whole lot more in the new book "Heart 411: The Only Guide to Heart Health You'll Ever Need." The 550-page paperback, which goes on sale Jan. 31, was written by two of the Cleveland Clinic's top heart doctors.
Cardiac surgeon Marc Gillinov, who has one of the largest practices in robotic and minimally invasive mitral valve repair in the world, gained national attention when he operated on comedian Robin Williams' heart in 2009. And Steven Nissen, the Clinic's chairman of cardiovascular medicine, has appeared in the national media speaking out against unsafe, ineffective drugs.

World first as British surgeons use robotic arm for heart operation January 16, 2012
British doctors have saved a man's life in a world-first operation using robotic technology.
Surgeons at St Mary's Hospital in London used the £800,000 robot to repair a complex blood vessel defect that would have proven fatal if left untreated.
Mr Barry Merchant, 67, was the first patient to be operated on in this way last week. He was suffering from an abdominal aortic aneurysm, which is the weakening of the wall of the main blood vessel that runs from the heart to the abdomen, causing part of it to swell.
Because Mr Merchant’s aneurysm was very close to the arteries leading to his kidneys, he required a specially fitted stent to be inserted that would reinforce the vessel while allowing blood to flow to branching vessels.
It can be extremely difficult to fit a metal stent by hand so surgeons used the Magellan Robotic System, directed with a joystick, to implant it in the swollen section.
The new robotic system called the "Magellan Robotic System" is controlled from a console outside of the operating theatre. It shows an internal picture of the patient’s blood vessels on screen and allows the clinician to navigate through them with a flexible robotic catheter. The clinician can steer the catheter and manipulate its moveable tip and joints to access hard to reach parts of the patient’s anatomy....read more
New research in International Journal of Robotics Research
Los Angeles, London, New Delhi, Singapore and Washington DC (Dec 11, 2009) – If you've been waiting for the day to arrive when computers actually start performing surgery, that moment might soon be upon us. A French team has developed a computerized 3D model that allows surgeons to use robotics to operate on a beating heart, according to a report in The International Journal of Robotics Research, published by SAGE.
The robotic technology predicts the movement of the heart as it beats, enabling the surgical tools to move in concert with each beat. It means that the surgeon can perform a procedure as if the heart was stationary. This development could be very important for millions of patients who require less invasive surgical heart procedures, where stopping the heart from beating would cause unnecessary risk.
Rogério Richa, Philippe Poignet and Chao Liu from France's Montpellier Laboratory of Informatics, Robotics, and Microelectronics developed a three-dimensional computerized model that tracks the motion of the heart's surface as it beats. In addition to the heart, this model also accounts for the movement of a patient's chest wall during breathing. Known as the "thin-plate spline deformable model", this new computerized approach allows the robotic arm to continually adjust to heart and chest movements during surgery.
The new approach relies on a mathematical representation of the heart's surface as it moves in three dimensions during pumping. Researchers have made many attempts to use computer modelling to account for heart and breathing motion. However, previous efforts have relied on 2D imaging combined with other steps, making them to slow to provide instantaneous feedback during an operation. This new 3D imaging predicts the heart movements in a single step, making it faster in real-life surgical environments.
Over the last 10 years, robotic arms have become essential in many kinds of surgical procedures, including microsurgery and operations that require extremely delicate movements. However, these machines also prevent the surgeons from using their sense of touch and coordination to adjust for rapidly changing environments. This new computer-generated model makes it possible for the surgeon to focus on suturing or cutting without having to adjust for the moving surface. Ultimately, this breakthrough will have many potential applications including heart surgery, coronary bypasses, and many kinds of brain surgery.
This is the first successful attempt to effectively isolate the physical movements of the heart and lungs during surgery. This has been particularly difficult given the heart's irregular shape, as well as its tendency to expand outward in all directions during beating. The heart's irregular surface also makes it more difficult to use visual tracking to accurately pinpoint movement.
This important development will allow surgeons to perform less invasive procedures that are not "life-or-death", but that do require a high level of precision and can have life-altering consequences for patients worldwide. To date, patients have gone without many of these procedures because the risk of complications during surgery outweighed the benefits.
