APPARATUS AND METHOD OF DELIVERING BIOMATERIAL TO THE HEART

摘要

A biomaterial for treating or preventing congestive heart failure is injecte d into the intrapericardial space of a patient's heart to apply a mild compressive force on the heart. A volume of biomaterial is placed in the intrapericardial space by an injection needle or catheter, adjacent at least the left ventricle, so that the biomaterial applies a compressive force on t he myocardium to relieve cardiac wall tension during at least a portion of the cardiac cycle.
