Electrical medical lead with textured stylet guide

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.
