Magnetic electrical connectors for biomedical percutaneous implants
First Claim
1. A biomedical percutaneous connector for providing electrical connection between electrical conductors located externally of a patient'"'"'s body and electrical conductors implanted underneath the patient'"'"'s skin, said connector comprising:
- (a) pair of mating connector elements;
(b) a magnet carried within one of said mating connector elements;
(c) magnetic material carried within the other of said mating connector elements;
(d) one of said mating connector elements being a female socket including;
(i) a hollow portion having an outer end portion thereof adapted to be extended outwardly through said patient'"'"'s skin;
(ii) an inclined inner wall surface provided on said outer end portion to form a conical recess within said hollow portion;
(iii) inclined electrically conductive contacts positioned adjacent said inclined inner wall surface and connected to said electrical conductors implanted underneath said patient'"'"'s skin;
(e) the other end of said mating connector elements being a male plug including;
(i) a non-conductive body having an inclined outer wall surface complementary in shape to said conical recess within said female socket;
(ii) inclined electrically conductive contacts carried on said inclined outer wall surface and connected to said electrical conductors located externally of said patient'"'"'s body;
(f) whereby when said male plug is inserted in said conical recess of said female socket, said inclined electrically conductive contacts thereof are held in wedging engagement with each other by the magnetic force between said magnet and said magnetic material.

Abstract
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.
