Robot could improve the treatment of cardiac catheter.

Atrial fibrillation of ScienceDaily — (16 September 2010) is a disease that affects more than two million Americans heart and is regarded as a substantial contribution to the blood clots and stroke. Now researchers at North Carolina State University develop a new computer catheter that could make faster, cheaper and more effective - the surgical treatment of atrial fibrillation and reduced significant radiation exposure related to the treatment.

"" We develop a robot catheter with significantly greater maneuverability and control,"says Dr. Gregory Buckner, Professor of air and space in NC State and mechanical engineering and principal investigator of the new catheter development team.""This should reduce the time it takes to the listener ablation procedure run and improve patient outcomes".

Atrial fibrillation is the heart, if random electrical activity in the upper Chambers of the heart, the aurículas.Esto makes to work less efficiently and can führen.Es dizziness and fatigue can also to the pool in the heart that bears to blood clots increases blood lead and the risk of stroke.

Doctors have developed a technique of Cardiac Ablation which mitigates by inserting a catheter into the hearts and then use atrial fibrillation heat cold or extremely small scars on the walls of the affected Atria.These scars block electrical signals problemáticas.A in this procedure, doctors who used keep track X-rays on the tip of the catheter-that exposure to create patient and physician radiation.

Existing commercial catheter be controlled manually and can require only in two directions moves rights.the catheter carefully manipulate the catheter control exactly where each individual injury doctors should be applied.

But the robot catheter developed by Buckner substantial uptime, "smart materials" significantly reduce offer better maneuverability.Smart materials internally contracting serve as muscles, if you apply a current ELÉCTRICA.Esto allows the catheter to bend to the left, right, then follow above, below, or a combination of addresses.In can addition, doctors a specialized joystick points atrium.A computer program to search curve connect points - in the main points for the - creating a solid line of electrical signals that block scar tissue causes atrial fibrillation.

"" If we can reduce the duration of the proceedings, at the same time exposure to radiation for doctors and patients, will reduce"says Buckner.""Savings at the expense of hospitals and health insurance companies also offer."

Researchers received a scholarship of the national institutes of health II small business innovation to take research phase in August be "robotic catheter" prototype from the lab and put it in the hands of the Médicos.La $ 1.1 million grant funds two years of development and testing chirurgische.die half of this sum is about NC State, walk, while the rest of the southeastern part of the TechInventures go to help bring technology to the market.

Buckner research team members include Dr. Bruce Keene and Dr. Guillaume Chanoit, NC State College medicine and veterinary medicine and Dr. Salim Idriss, a pediatric Electrophysiologist in Duke University Medical Center.Evaluaciones surgical your prototype robot catheter in 2011 starts.

Other groups who marketed their own designs of the robot catheters, but they require, multi-million dollar investments and custom catéter. Tecnologia Buckner laboratories could exist, load at a fraction of the cost of a larger number of patients due to the significant cuts in the initial and operating cost as well as logistical concerns.
