Pacemaker
First Claim
1. A pacemaker usable to stimulate an organ such as the heart comprising a suture-free casing housing a pulse generator connected to at least one electrode tip forming part of the outer surface of said casing and being electrically insulated therefrom, said electrode tip comprising means for directly entering into non-perforating contact with the epicardium of the heart without piercing the epicardium.

Abstract
The pacemaker includes a casing housing a pulse generator having at least one electrode tip preferably projecting out of said casing and being insulated therefrom, whereby no plug-receptacle nor electrode catheter is required. The pacemaker is to be surgically located below the heart in the virtual cavity formed between the epicardium and the pericardium with its electrode tip in close contact with the epicardium of the heart.

14. A method of direct contact implanting of a pacemaker onto the epicardium outer surface of a heart of a human patient, said pacemaker comprising a casing housing a pulse generator connected to at least one electrode tip forming part of the outer surface of said casing and being electrically insulated therefrom, said electrode tip comprising means for directly entering into non-perforating contact with the epicardium of the heart, said method comprising the steps of providing access to the patient'"'"'s pericardium by a subxiphoid abdominal approach which comprises opening said pericardium to gain access to the pericardial sac, slipping said pacemaker into the cavity existing between the inner surface of said pericardium and the outer surface of said epicardium so that said pacemaker is located at the lower portion of the pericardial sac and is in contact with said heart, establishing a good electric contact with the epicardium and thereafter closing the opening in said pericardium.
