Device to permit offpump beating heart coronary bypass surgery

摘要

A system for manipulating a heart during cardiac surgery permits coronary surgery on a beating heart while maintaining cardiac output unabated and uninterrupted. Circumflex coronary artery surgery can be performed using the system. A component of the system engages the heart with a heart positioning device, repositions the heart into a displaced position and maintains it in the displaced position while the heart continues to beat with substantially unabated and uninterrupted cardiac output. One form of the system can be used in minimally invasive surgery.
