    摘要: An implantable lead having a plastic stylet guide therein. A substantially cylindrical channel is provided in a flexible lead body made of silicone rubber, polyurethane, or the like. The cylindrical channel defines a lumen containing a stylet guide into which a stylet can be inserted during an implantation procedure. Texture on the inner wall of the stylet guide minimizes friction between the stylet and the stylet guide, facilitating easy insertion and removal of the stylet. One or more electrical conductors may also be provided.

    摘要: The present invention provides resistance to degradation from environmental stress cracking (ESC) and metal ion induced oxidation (MIO) for implantable, flexible pacing lead insulators having a body of polyether polyurethane elastomer material. A thin layer of a second polyurethane elastomer is applied as an overcoat to the lead insulator body. The second polyurethane is more resistant to ESC and MIO than the elastomer comprising the body of the insulator. Because ESC and MIO are surface phenomina, only a thin layer of the second material is required and the mechanical properties of the base material will determine the overall mechanical properties of the lead insulator.
