Catheter-based methods for remodeling a heart chamber

An anchor for securing in a wall of a heart, the anchor comprising:

• a central body comprising an inner body and an outer body, the inner body having a proximal end and a distal end, and the outer body having a proximal end and a distal end;
• at least one inner wing extending radially outward from the inner body between the proximal end and the distal end;
• and
• at least one outer wing extending radially outward from the outer body between the proximal end and the distal end, the at least one outer wing extending radially outward beyond the at least one inner wing.

An anchor for securing in a wall of a heart, the anchor comprising:

• a central body having a proximal end and a distal end;
• a plurality of wings extending radially outward from the central body between the proximal end and the distal end;
• and
• a suture lock configured to trap at least one suture between opposing layers of the suture lock.
