    摘要: A bio-implant having a length and a proximal and a distal end. The bio-implant has at least two lamina of dielectric material joined together, thereby defining a boundary and also defining a side surface that is intersected by this boundary. In addition, at least one set of conductors is interposed between the two lamina and extend lengthwise from the proximal end toward the distal end, each one of the set of conductors being terminated adjacent to the side surface to form a set of conductor terminations. Further, a set of electrode contact points are constructed on the side surface, with each electrode contact point contacting one of said conductor terminations.

    摘要: A biologically implantable percutaneous connector (20) for providing optionally separable interconnection between an implanted connector (21) attached to bone tissue and a removable connector (40). The connectors each include a supporting matrix of dielectric material (86, 94) within which an array of tiny conductive rods (90, 88) are sealed with ends (112, 110) of the rods exposed as contacts at mating faces (94, 92) and the other ends (102, 100) joined to conductors (33, 43) of cables (32, 42). Elastomeric anisotropic connector material (44) is located between corresponding arrays of contacts to provide for repeated reliable electrical connection and disconnection of corresponding contacts. External surfaces of the implantable body (21) of the percutaneous connector may be coated with a bioactive material promoting integration of surrounding tissue into the surfaces of the implanted percutaneous connector. A contact block (22, 62) including the mating face (94, 92) and a terminal face (98, 96) to which the conductors of a cable are individually connected is made by shaping an array of conductive rods (90, 88) and supporting dielectric material to form a smooth surface including dielectric matrix material and the ends of the electrically conductive rods.

    摘要: A miniature, electrically-insulated multi-conductor electrical cable suitable for implantation in living bodies and readily connected to sensors or electrodes, and implantable microelectrodes attached to such cables. Individual electrical conductors are coated with at least one layer of, insulating material and stranded together, or optionally bound together by an additional layer of insulating material which is compatible with implantation in living bodies. The individual conductors are separated from one another in terminal portions of the cable and are held by a ribbonizing resin at a predetermined pitch to facilitate connection of each of the conductors. The terminal portions may define microelectrodes. Another microelectrode includes an electrically conductive electrode core member sharpened and coated with a thin layer of a dielectric material. An extremely small area of the core at the sharpened point is exposed by ablating the dielectric material by the use of an ultraviolet laser beam scanned over the material. Multiple conductor microelectrodes may also be supported within a hollow needle or in flat ribbon configuration, with openings in dielectric material defining active electrode sites. Multiple active electrode sites may be defined on a microelectrode accompanied by an integrated circuit after connection of the integrated circuit to a multiconductor cable.

    摘要: Connectors for attachment to cables including a large number of very small flexible conductors or conductor pairs, in which very small contacts are provided as an array exposed on a flat mating surface. Contacts may be raised slightly above the flat surface by plating conductive metal to form raised bumps on one of a pair of connectors. Individual conductors are placed through apertures defined in a substrate acting as a template, and are potted in place before shaping the mating surface of the connector. Contact bases to be plated may be defined precisely by photoresist lithography on a cover layer attached to the template substrate, and an elastomeric layer may be provided between the cover layer and the template substrate. Pin and socket combinations are used to align mating connectors with each other.
