ABSTRACT:
The self-suturing porous electrode assembly includes an electrode with a finely grained porous coating and a wire, both embedded in a silicone rubber body with a contact face of the electrode protruding from a lower surface of the body. The body is generally planar with pairs of holes therethrough for receiving the legs of U-shaped spring anchor members of surgical spring steel. Each pair of legs is connected at the upper ends thereof to a bight and have at their lower ends sharply pointed outwardly, and downwardly sloping curved prongs which are spring biased outwardly. In an upper armed position the prongs are retained in tensioned condition adjacent the lower surface of the body by means of one or two wedges inserted between the upper surface of the body and the bights. Activation is achieved by removal of the wedges which allows the legs to move downwardly in a spread apart, snap action movement so as to drive the prongs downwardly and outwardly into adjacent myocardial tissue.
