Claim:
1. A method for treating a heart in a patient, comprising: advancing a distal end portion of a delivery catheter to a position adjacent heart tissue at a first location, wherein the distal end portion comprises a distal end sheath having an anchor therein, wherein the anchor is configured to radially expand from a delivery configuration to a tissue-engaging configuration, wherein the anchor comprises a central body having a central lumen and a plurality of radially extendable elements positioned around a circumference of a distal end of the central body, wherein in the delivery configuration the radially extendable elements are radially retracted, and wherein in the tissue-engaging configuration the radially expandable elements are radially extended in flowered fashion away from the central body, wherein the radially extendable elements are formed from nitinol, wherein during advancing of the distal end portion the radially extendable elements are compressibly held in the delivery configuration within the distal end sheath; deploying the anchor into contact with heart tissue at the first location, comprising releasing the anchor from the sheath whereby the anchor transforms from the delivery configuration to the tissue-engaging configuration wherein the radially extendable elements radially extend away from the central body into contact with the heart tissue at the first location; passing an elongate member from the first location, across a heart chamber, and through a heart wall, wherein a first end of the elongate member is secured to the anchor; securing a clip to heart tissue at a second location, wherein the second location is an apex of the heart, wherein the clip is configured to slidingly receive the elongate member and to lock onto the elongate member to prevent sliding movement by the elongate member with respect to the clip, wherein the second location is on the opposite side of the heart wall from the first location, wherein the elongate member is slidingly received within the clip; adjusting the length of the elongate member between the anchor and clip by sliding the elongate member within the clip such that the elongate member extends across the heart chamber and provides tension between the anchor and the clip; locking the clip to the elongate member to prevent sliding movement therewith; and removing the delivery catheter from the patient.
