Abstract

An electrode adapted for implantation for effecting the intracardial stimulation of a heart through the intermediary of an implanted heart pacemaker. The electrode, without the need for a barb on the electrode head, may be securely placed within the heart, and in which it is also afforded that, as required, a safe relocation thereof may be carried out in which no injury is occasioned of the muscle tissues encompassing the electrode head. The foregoing includes means for the anchoring of the electrode head, comprising a receptacle of a variable volume which is connected with the electrode in a region proximate to the electrode head, and with the receptacle incorporating at least partly elastic walls and a closable connecting conduit for the filling of the receptacle.
