Patent Images
1. A body implantable cable comprising:
- a. a substrate of flexible, biocompatible, electrically insulative material with a first surface and having a proximal end and a distal end and having a crease between said proximal end and said distal end whereby a first portion of said first surface is placed adjacent a second portion of said first surface;
b. a line of conductive ink fixedly attached between said proximal end and said distal end of said first surface of said substrate; and
c. means for sealing said first portion and said second portion of said first surface of said substrate from the invasion of body fluids and tissue.

Abstract
A stimulation lead for electrically coupling an implantable pulse generator to an electrode in an apnea treatment system and method of making same. The lead employs a thin substrate of polyurethane or other highly flexible implantable material. Conductors are placed on the substrate by silk screening a conductive ink. The ends of the lead are electrically terminated using rivets which couple through the substrate. The substrate is folded to enclose the conductors, thereby insulating them and protecting them from bodily fluids. Suitable connectors may be attached to either end. The resulting lead is easily fabricated and is extremely thin and flexible.
