  • Method of centerless ground finishing of feedthrough pins for an implantable medical device
    Patent number: 6076017
    Abstract: A centerless grinding method of finishing feedthrough pins and corresponding devices for use in implantable medical devices and for components such as batteries in implantable medical devices is disclosed. The method provides certain advantages, including the elimination of longitudinal anomalies in drawn wire to thereby improve the hermeticity of implantable medical devices. In one of the preferred methods, the surface of an over-size medical grade wire having a known anomaly depth is centerless ground using an abrasive wheel and suitable coolant to a layer past which those anomalies disappear.
    Type: Grant
    Filed: February 11, 1998
    Date of Patent: June 13, 2000
    Assignee: Medtronic, Inc.
    Inventors: William J. Taylor, John D. Wright, Joseph F. Lessar, Gary F. LaBree
  • Centerless ground feedthrough pin for an electrical power source in an implantable medical device
    Patent number: 5871513
    Abstract: The present invention relates to centerless grinding methods and corresponding devices such as feedthroughs for implantable medical devices and for batteries for implantable medical devices. The present invention provides certain advantages, including the elimination of longitudinal anomalies in drawn wire and increasing the reliability of implantable medical devices. In a method of the present invention, the surface of an over-size medical grade wire having a known anomaly depth is centerless ground to a depth past which those anomalies disappear. Centerless grinding of the present invention may be accomplished using an abrasive wheel and suitable coolant.
