Porous pacemaker electrode tip using a porous substrate

Image Number 5 for United States Patent #4784161.

An implantable stimulating lead for a cardiac pacemaker has a distal tip having a surface area adapted to physically contact heart tissue for pacing the heart tissue, sensing heart contractions and promoting tissue ingrowth. The distal tip includes a conductive electrode and a porous non-conductive substrate, which together define the surface area of the distal tip. The conductive electrode and porous substrate are provided as first and second members, although the surface area of each is adapted to present a singular, smooth distal tip region for the electrode lead.
