ABSTRACT:
A heart muscle irrigation device comprises a short rivet like member with one closed and one open end, and a barrel including a plurality of holes, slots, an area mesh, or a grid. The irrigation device is inserted into the heart muscle so as to provide a channel from, for example, the left ventricle, to provide ad adequate oxygenated blood supply to a starved muscle. The irrigation device is inserted from either outside or inside the rib cage by an insertion device. The insertion device comprises a plunger and barrel assembly adapted to contain the irrigation device. The tip of the insertion device includes members adapted to penetrate the heart muscle. If the irrigation device is inserted through an insertion into the rib cage, an applicator comprising a tubular member with a planar tip including a soft elastomeric seal can be used whereby a portion of the heart muscle is held more or less rigidly for the short period during which the irrigation device is inserted. These devices, even when a rib cage insertion is made, do not require either the life support systems or the extensive rib cage damage associated with conventional bypass surgery.
