Soft Catheter Surgical Robot for Heart Disease (20150147, Dr. Tim Kowalewski)
Surgical robot for treating cardiovascular disease (CVD)
A new type of soft surgical robot capable of safely travelling through vasculature offers surgical robotic benefits in treating cardiovascular disease (CVD). The worm-like design is based on fiber-reinforced elastomeric enclosures (FREE). It features hydraulically powered actuators with pressure-threshold valves, offering integrated sensing and precision control at the end-effector. The robot can anchor itself within vasculature using minimal force and will not block blood flow. Combining FREE actuators enables bidirectional traversal, steering and anchoring for interventional procedures by the catheter tip (e.g. atherectomy). The technology can be combined with other tools such as closed-loop laser photoablation and fiber optic tissue sensing to realize safe, closed-loop precision tissue removal in transvascular conditions with semi or fully automated control.
Safely removes plaque
Heart disease remains a leading cause of death, yet no safe, minimally-invasive and lasting clinical intervention currently exists to treat it. Stent usage is declining and proving clinically inferior to invasive bypass surgery. This new, unprecedented design provides an inherently safe method of removing plaque while extending the benefits of surgical robotics into the cardiovascular and transvascular space.
