Electrode system for use with an implantable cardiac patient monitor

An electrode system for use with a fully implantable cardiac monitor of the type including electrical circuitry for monitoring the physiology of the human heart and having an enclosure for containing said electrical circuitry, said electrode system comprising:

• first and second flexible insulative conduits;
• first and second electrode means carried by each of said first and second conduits respectively, said first and second electrode means comprising strip electrode means including an elongated strip of flexible material including a plurality of spaced apart discrete conductive electrodes embedded therein, said electrodes having an exposed major surface, each said elongated strip of flexible material including opposing longitudinal walls and a plurality of spaced apart fixation projections projecting from said longitudinal walls, said fixation projections forming acute angles with said longitudinal walls;
• conductor means extending through said first and second conduits and into said header for coupling said electrodes of said first and second electrode means to said electrical circuitry,
• said conduits and said electrode means being implantable beneath the skin of a patient to dispose said electrodes in non-touching proximity to the heart for establishing electrical contact between said electrodes and the heart.
