ABSTRACT:
An electrode carrying member which is inserted with forceps into the epicardial muscle and which comprises a substantially parallepipedic elastic body having two large planar faces; two parallel long sides and two parallel short sides, a conductor attached to the first one of the large faces; four small inwardly curved teeth attached to the second large face close to the corners thereof; each tooth having a sharpened thin point; the teeth next to each of the long sides being arranged in a straight line running parallel to said long sides with the points of opposing pairs of teeth directed towards each other and forming an arc of a circle separated by a gap; a thin electrode point projecting from the center of the second large face midway between said opposing pairs of teeth; a stub projecting from each of the short parallel sides and receptacles on the forceps receiving the stubs. Prior to insertion the stubs are placed in the receptacles of the forceps and on manually closing the forceps, the elastic body is bent back on itself until the curved teeth are substantially parallel one with the other and parallel to the electrode point so as to permit their being driven into the heart muscle without tearing the muscle and on releasing the forceps the elastic body being allowed to resume its original shape causing the curved teeth to be further embedded in the heart muscle with minimum damage to the tissue.
