Abstract

A porous cardiac pacemaker electrode comprising a concavo-convex electrode cap having a plurality of apertures therethrough and an electrode shaft having a supporting edge formed thereon to which the concave surface of the electrode cap is joined. The porous cardiac pacemaker electrode is produced by deforming a platinum plate into a concavo-convex shaped cap member, forming a plurality of selectively spaced apertures through the electrode cap member to make the electrode cap substantially porous, forming an electrode shaft having a supporting edge, and joining the supporting edge of the electrode shaft to the concave surface of the electrode cap member.
