Claim 13:
14. A method of anchoring an artificial chordae tendineae to a papillary muscle or heart wall, the method comprising:
inserting a catheter through a heart valve, the catheter containing an anchor having a body portion coupled to an artificial chordae tendineae;
positioning the catheter adjacent to a targeted papillary muscle or heart wall;
moving the anchor out of the catheter so that the anchor moves from a delivery configuration to a deployed configuration, wherein when the anchor is in the delivery configuration the anchor has a first outer dimension and when the anchor is in the deployed configuration the anchor has a second outer dimension, the first outer dimension being smaller than the second outer dimension;
engaging the tissue-engaging portion of the anchor with the targeted papillary muscle or heart wall when the anchor is moved to the deployed configuration; and
extending the artificial chordae tendineae from the body portion of the anchor to a heart leaflet;
wherein:
in the delivery configuration, the tissue-engaging portion of the anchor includes a plurality of elongated arms extending distally away from the body portion with distal tips thereof directed radially-inwardly toward the body portion such that the distal tips do not contact the catheter; and
in the deployed configuration each of the elongated arms of the anchor has a central portion extending radially away from the body portion of the anchor, a distal end extending radially toward the body portion of the anchor and axially toward the body portion of the anchor, and a distal tip extending axially toward the body portion of the anchor and radially away from the body portion of the anchor.
