Patent ID: 7311731

Claim:
A method for direct localized therapeutic treatment of myocardial tissue in heart having a pathological condition comprising the steps of: identifying a target region of the myocardium to be stiffened, restrained, or constrained, the target region comprising at least one of a peri-infarct region and an infarct region; advancing at least a portion of a device across the septum of the heart to deliver material suitable for stiffening, restraining or constraining infarct tissue; and applying said material directly and substantially only to at least a portion of the myocardial tissue of the target region substantially identified in the identifying step to physically modify the mechanical properties of said tissue effective to alter the geometry and wall stress on peri-infarct tissue and to limit motion in at least one of the peri-infarct and infarct region by stiffening, restraining, or constraining the tissue in the region effective to improve cardiac function.
