Abstract: An implantable electrode array is provided, the electrode array comprising a substrate, the substrate having a front side and a back side, and a first number of first electrodes. The first electrodes are formed as contact pads, and are arranged on the front side. The substrate comprises a second number of prefabricated holes at predetermined positions, the holes extending from the front side through the substrate towards the back side, and being arranged such the holes may be penetrated by elongated electrodes placed at the predetermined positions.

Abstract: An intraoperative multichannel brain probe is presented. The brain probe has a cylindrical upper stainless steel section attached to a lower cylindrical section. In the lower section, an outer cylindrical tube surrounds a second insulating tube. Electrically recording/stimulating wires are placed between the outer tube and the second tube. Each wire has one end protruding out a hole in the outer tube. The other end of each wire is threaded through the entire probe and electrically connected to a recording or stimulating device through a connector system. A number of insulating tubes and electrodes located inside the second tube may also be part of the brain probe. Each inner electrode, typically two, is insulated from each other and from the second insulating tube by other insulating tubes. The combination of one or more wires and electrodes provides a multi-functional device.

Abstract: 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.

Abstract: A biologically implantable percutaneous connector for providing optionally separable interconnection of a large number of small electrical conductors of an externally located electrical cable includes a mating face incorporating an array of exposed end surfaces of tiny conductive rods sealed in a supporting matrix of dielectric material which is supported in a connector body. Elastomeric anisotropic connector material is located between corresponding arrays of contacts to provide for repeated reliable electrical connection and disconnection. External surfaces of the implantable body of the percutaneous connector are coated with a bioactive material promoting integration of surrounding tissue into the surfaces of the implanted percutaneous connector.
