ABSTRACT:
A catheter type electrode member for an implantable pacemaker, insertable from without from the epicardium into the heart muscle for cardiac stimulation, of the type comprising a holder of dielectric elastic material including a stem terminating in an enlarged resilient pad having the shape of a platform. One major surface of the platform pivotally supporting an arcuately curved electricity conducting hook, which projects out of said pad and has its tip portion pointing back towards said major surface and preferably two spaced apart anchoring needles likewise projecting out from said major surface, conveniently in a diverging manner. Upon insertion from the outside through the epicardium of the hook into the heart muscle by a tool gripping the hook, release of the hook allows the elastic pad to expand against the outer heart surface at the same time as the anchoring needles are made to penetrate also into the epicardium, thereby positively anchoring the electrode member in position. The hook is pivotally connected to a conductor passing through said pad and stem, and to be connected to an electric pulse generator.
