51. A method for treating ischemic congestive heart failure in a patient comprising the steps of:
-
identifying akinetic tissue within a heart chamber wall;
making an incision through the akinetic tissue in the chamber wall;
inserting a single component shaping device into the chamber through the incision, wherein said shaping device comprises a compliant material and is configured to be placed inside the heart chamber to help prevent the result of a chamber that is too small;
