Robotic-Assisted Cardiac Stent System Enhances Control And Improves Visualization

Innovative System a Big Leap Forward for Patients and Physicians Alike

Thousands of cardiac stent procedures are successfully performed every year, but a key challenge is positioning the stent, guidewires, and at the precise location of the blockage. In addition, even with the most sophisticated X-ray technology, the complex shape of the heart and the twists and turns of the coronary arteries make the exact size of the blockage difficult to visualize and measure. As a result of these challenges, 10-20 percent of patients require a second stent due to inaccurate placement or size of the first stent.

The CorPath 200 System, a new robotic-assisted percutaneous coronary interventions (PCI) system, was recently approved for use by the FDA, based on the findings of the CorPath PRECISE trial, led by investigators from NewYork-Presbyterian Hospital/Columbia and St. Elizabeth’s Medical Center in Boston.

“This novel system, which enhances positioning by manipulating the catheter, stent, and guidewire at the same time, also provides improved and blockage measurement,” says Dr. Giora Weisz, director of clinical research at the Center for Interventional Vascular Therapy at New York-Presbyterian Hospital/Columbia University Medical Center and associate professor of medicine at . Equally important, he notes, the robotic system gives him more control than the conventional approach by allowing him to move the guidewire and stent in increments as small as one millimeter. In addition, the CorPath 200 System allows the interventional cardiologist to perform the cardiac stent procedures remotely, while seated in a radiation-protected cockpit next to the patient’s bed. As Dr. Weisz sees it, “The improved positioning, imaging, overall control, and radiation protection add up to a win-win for patients and doctors alike.”

NewYork-Presbyterian Hospital/Columbia University Medical Center is currently piloting the new robotic-assisted percutaneous coronary interventions (PCI) system and has plans to provide this new technology to patients in the coming year.

Cardiac stent procedures restore blood flow to blocked arteries in patients with . A cardiac stent acts like a scaffold to support and open a blocked . As part of a cardiac stent procedure, a catheter tipped with a small deflated balloon inside a closed steel mesh stent is inserted into a under the guidance of X-rays and contrast dyes for visualization. Once the stent is in place, the balloon is inflated, expanding the stent to the exact size of the artery. The deflated balloon is then removed.
