摘要: 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.

摘要: Implantable electrodes for defibrillation are formed of pluralities of electrode segments. Each of the segments is relatively long and narrow. The electrode segments can be parallel and spaced apart from one another a distance at least ten times the nominal width, with one end of each segment mounted to a transverse distal portion of an electrically conductive lead coupling the electrode to a defibrillation pulse generator. Alternatively, segments can branch or radiate outwardly from a common junction. In yet another arrangement, electrode segments are portions of a single conductive path at the distal end of a lead from a pulse generator, arranged in either a spiral configuration or a serpentine configuration which can align electrode segments side by side, parallel and spaced apart. The electrode segments can be formed of composite conductors in the form of titanium ribbons or wires with a sputtered outer layer of platinum, or a silver core in a stainless steel tube, with a platinum layer formed onto the tube. The electrodes are highly compliant yet can provide large effective areas for defibrillation, enabling a transthoracic pulsing arrangement of two electrodes on opposite sides of the heart, implanted subcutaneously outside of the thoracic region.

摘要: 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.

摘要: Body-implantable leads with open, unbacked (uninsulated) electrode structures having electrical discharge surfaces formed by conductive elements, such as mesh and braid, and preferably coils. The electrode structures can be classified by pattern: (1) loops, (2) linear arrays and (3) radial arrays. The electrodes are located on or near the epicardial surface of the right and left heart.

摘要: A body implantable cardioversion/defibrillation device includes an electrically conductive lead, three lead extensions coupled to the lead through a junction body, and an electrode array consisting of three electrodes, one electrode being coupled to each of the lead extensions. Each electrode has several separate electrically conductive paths, including a primary conductor in the form of a helically wound coil, and a linear shunt conductor in the form of a cable surrounded by the primary coil. The shunt cable is a composite, including a DBS core surrounded by an insulative coating. A dielectric sheath surrounds the shunt cable, preventing the cable from contacting the primary coil and isolating the shunt cable from contact with body tissue or body fluids. At each end of each electrode is a connector structure including a shunt connector attached to an end of the shunt cable, and an outer coil connector surrounding an end of the primary coil and the shunt connector. Both connectors are crimped to maintain the electrical and mechanical coupling. The junction body includes an electrically conductive plate having several bores directed inwardly into the plate. A thin wall portion on one side of each bore can be crimped following insertion of each lead or lead extension, to secure the electrical and mechanical connection.
