Physiological and electrical characteristics of the porous endocardial electrode.
The principal complications in pacemaker therapy involve electrode-tissue instability. A new porous electrode has been devised that allows tissue ingrowth into the electrode interior, improving electrode biocompatibility and resulting in reduced dislodgment incidence, lower pacing thresholds, and improved sensing. Electrode porosity reduces polarization impedance permitting small-electrode design for both improved pacing longevity and optimal sensing function.
