    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 titanium alloy. Materials of such composition have been found to have suitable conductivity for use with implantable pulse generators and suitable fatigue strength when used in endocardial lead placement. Moreover, such materials have been found to pass tests intended to detect metal ion oxidation (MIO) in susceptible polymeric materials.

    摘要: An implantable lead including one or more sigmoidal or serpentine shaped conductors which are placed in one or more lumens formed in and extending along the length of the lead body. The conductor is shaped with its undulating curve lying generally in one plane. The lumen in cross section is greater in width than in height. The sigmoidal conductor extends along the length of the lead body and across the width of the lumen.
