Magnetic electrical connectors for biomedical percutaneous implants

摘要

A biomedical percutaneous connector for providing electrical connection between electrical conductors carried externally of a patient's body and electrical conductors implanted within the body of the patient. The connector includes a socket having an enlarged disk shaped base portion for being implanted below the patient's skin. A cylindrical portion is integral with the base portion and extends outwardly of the skin. A conical recess is provided in an upper end of the cylindrical portion and has a magnet located in the base thereof. Inclined conductive strips are carried on an upper end of the cylindrical portion adjacent the conical recess to which electrical conductors are attached and extend into the patient's body. A complementary shaped plug which also has electrical contacts provided thereon is adapted to fit within the conical recess of the socket. Guide grooves and protrusions are provided on the socket and plug for aiding in positioning the plug relative to the socket. The plug is held in the socket by the magnetic force between the magnet located in the base of the cylindrical portion and magnetic material provided in the plug.
