ABSTRACT:
Means and methods of creating an autogeneous pumping chamber for ventricular replacement or ventricular assist while avoiding heart transplantation. A chamber is created by wrapping a major muscular mass around a silastic-type pouch which is thereafter filled with isotonic saline. The muscular mass is then allowed to grow together over time to create an autogeneous fluid-tight pumping chamber, the pouch is then drained and removed, and the autogeneous chamber is relocated to its needed location, and thereafter grafted into operative relationship within the cardiovascular system.
