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.

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 super austenitic stainless steel having a composition of at least 22% nickel and 2% molybdenum. 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.

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.
