Claim 0:
1. A method of anchoring a suture in a heart of a patient as an artificial chordae, comprising:
intravascularly accessing the heart;
inserting a suture into a heart valve leaflet of the heart;
attaching a portion of the suture to a cardiac anchor, the cardiac anchor including an actuation head at a proximal end of an anchor body, a coil extending distally of the anchor body having a distal tip, a flexible shaft extending from the anchor body distally through the coil, and a blunt tip at a distal end of the flexible shaft;
advancing the anchor to a heart wall of the heart with an anchor delivery catheter;
engaging an actuation mechanism with the actuation head to rotate the anchor;
actuating the anchor to drive the blunt tip against the heart wall to cause the flexible shaft to flex against the heart wall and orient the coil generally parallel with the heart wall;
further actuating the anchor to rotate the coil and cause the distal tip of the coil to transversely enter the heart wall such that further rotation of the coil causes the coil to become embedded in and along the heart wall.
