    摘要: A method of evaluating an electrochemical cell for a metallic contaminant-caused defect. The electrochemical cell is configured for use with an implantable medical device and includes an anode, a solid cathode and a liquid electrolyte. The method includes storing the cell at an elevated temperature following assembly for accelerating corrosion of possible metallic contaminants. A parameter of the cell related to cell voltage is then measured. An evaluation is made as to whether the cell is defective based upon this measured parameter.

    摘要: A method of making a high reliability electrical connection in an implantable medical device. The electrical conductors may include metals such as niobium, molybdenum, tantalum, platinum, titanium, nickel and alloys thereof. The electrical conductors are resistance welded by establishing contact between the conductor pair, providing a protective atmosphere around the contacting pair, and applying electrical energy to the contacting pair to cause fusion while maintaining the protective atmosphere.

    摘要: An implantable medical device such as a defibrillator is described. The device includes an hermetically sealed housing containing a flat electrolytic capacitor and an energy source such as a battery. The battery is connected to the capacitor and provides charge thereto. The capacitor stores the charge at a relatively high voltage. The charge stored in the capacitor is discharged through a defibrillation lead to a site on or in the heart when fibrillation of the heart is detected by the implantable medical device. Methods of making and using the implantable medical device, the capacitor, and their various components are disclosed.

    摘要: A medical electrical lead of the type which includes an electrode at a distal end of the lead a connector at a proximal end of the lead and an elongated electrical conductor extending between the electrode and the connector. The conductor is comprised of a wire wound in a coil configuration with the wire comprised of a duplex stainless steel having a composition of at least 22% chromium, 3% molybdenum and 5% nickel. Material of such composition has been found to have suitable conductivity for use with implantable pulse generators and suitable fatigue strength when used in endocardial lead placement. Moreover, such material has been found to pass tests intended to detect metal ion oxidation (MIO) in polymeric materials.
