Co-radial, multi-polar coiled cable lead and method for making the same

摘要

A method for making a co-radial, multi-polar coiled cable lead. The method includes the steps of attaching a first end of a coated cable to a mandrel using a first end fixture. The coated cable comprises one or more cable strands, where each strand is made from one or more filaments. After the first end of the cable is attached to the mandrel, the cable is wound around the mandrel to form a coiled cable. A second end of the coiled cable is then attached to the mandrel using a second end fixture to retain the coiled cable under tension. Second stage processing is then performed on the coiled cable so that the end fixtures may be subsequently removed from the coiled cable without the coiled cable unwinding. After the second stage processing is complete, the coiled cable can be used in the manufacture of an implantable lead.
