Abstract
A novel method and apparatus for isolating and anchoring an implantable electrically stimulating probe such as a defibrillator patch electrode for use with an automatic cardioverter/defibrillator is disclosed in which a porous bio-compatible coating or enclosure covers and isolates the electrode in a way which allows electrical conductivity via bodily fluid which passes through but separates the electrode from the adjacent tissue in the manner of dissection plane which substantially prevents tissue ingrowth. The coating or enclosure controls the minimum separation distance from the closest tissue and which reduces the local current density applied to adjacent tissue when the electrode is pulsed. The system includes a provision for attaching the enclosure means to internal bodily tissue.
