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 of the extensive rib cage damage associated with conventional bypass surgery.

Dispositif pour irriguer le muscle cardiaque, comprenant un élément ressemblant à un court rivet ayant une extrémité fermée et une autre, ouverte, ainsi qu'un corps comprenant une série de trous, des fentes, un treillis ou une grille. On insère le dispositif dans le muscle cardiaque de manière à dégager une voie à partir, par exemple, du ventricule gauche pour approvisionner adéquatement en sang un muscle en manque d'oxygène. On l'introduit soit de l'extérieur ou de l'intérieur de la cage thoracique au moyen d'un dispositif d'insertion. Ce dernier comprend un ensemble piston et cylindre adapté pour contenir le dispositif d'irrigation. La pointe du dispositif d'insertion comprend des éléments adaptés pour perforer le muscle cardiaque. Si le dispositif d'irrigation est introduit par une insertion dans la cage thoracique, un applicateur comportant un élément tubulaire doté d'une pointe plane comprenant un sceau élastomérique souple peut être utilisé, alors qu'une portion du muscle cardiaque est maintenue plus ou moins rigidement pendant un court laps de temps durant lequel le dispositif d'irrigation est inséré. Ces dispositifs, même si l'insertion se fait par la cage thoracique, ne nécessitent pas de système de support vital et ne causent pas non plus les dommages importants à la cage thoracique associés à la chirurgie classique pour les pontages.
