  • Patent number: 5090422
    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.

  • Patent number: 5020544
    Abstract: An implantable cardiac electrode for use in defibrillation. The electrode comprises a plurality of layers of porous conductive screens and backed by an insulation layer. When implanted on or about the heart surface, body fluids can flow through the screens thus increasing the effective surface area of contact. Each individual layer of mesh can be microscopically textured to create indentations on the layer for further increasing the surface area of each screen, and thus, the surface area of body fluid contact. Also disclosed is an electrode without an insulative backing facing away from the heart.

  • Patent number: 4637405
    Abstract: A stimulator for inducing salivation by neural stimulation comprises a housing which may be received in the oral cavity of a user, the housing enclosing electronic signal generating means and electrodes for applying a signal to neurally sensitive areas of the oral cavity to induce salivation. In its method aspect, the invention involves stimulation of salivation by the application of an electrical signal to neurally sensitive areas.
