  • Ring connector for implantable medical devices
    Patent number: 8244357
    Abstract: An electrical contact for use in the header assembly of an implantable tissue stimulator includes a metal housing having a base and a sidewall where the opening in the base is adapted to receive the terminal of a medical lead therethrough. An electrical contact support member is welded to the edge of the sidewall and affixed to the support member are a plurality of spring members that are tangent to an imaginary circle whose diameter is slightly less than the outside diameter of the lead terminal contact rings. When the contacts are axially aligned in the device header, the terminal of an electrical lead may be longitudinally inserted into the header to establish electrical contact with device feedthrough wires that are joined to the electrical contacts in the header.
    Type: Grant
