Claim 0:
1. A system for anchoring an artificial chordae tendineae to papillary muscle or heart wall, the system comprising:
an anchor movable between a delivery configuration and a deployed configuration, the anchor being in the delivery configuration when disposed within a delivery catheter, the anchor being in the deployed configuration when the anchor is moved beyond a distal end of the delivery catheter;
wherein:
the anchor has a body portion and a tissue-engaging portion extending from the body portion;
in the delivery configuration, the tissue-engaging portion of the anchor is elongated and extends axially away from the body portion with a distal tip thereof directed radially-inwardly;
in the deployed configuration, the tissue-engaging portion of the anchor has a central portion extending radially away from the body portion of the anchor, a distal end extending radially and axially toward the body portion of the anchor, and a distal tip extending axially toward and radially away from the body portion of the anchor;
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;
the tissue-engaging portion of the anchor is engageable with a papillary muscle or a heart wall when the anchor is in the deployed configuration, and
the body portion of the anchor is configured to be coupled with the artificial chordae tendineae to anchor the artificial chordae tendineae to the papillary muscle or heart wall.
