Cardiac tissue anchoring devices, methods, and systems for treatment of congestive heart failure and other conditions

摘要

A heart tissue gripping device may include a body portion, an elongate shaft, and a tissue gripping member that is attached to the distal end of the elongate shaft. The tissue gripping member being may be positioned adjacent a heart surface by insertion through an incision in the body. The tissue gripping member may releasably attach to tissue of the heart surface to facilitate a surgical instrument in performing one or more procedures. A coupling of the tissue gripping member may releasably attach the surgical device to the tissue gripping member to allow the device to access the tissue of the heart surface.
