Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
107 words
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.
Claim 2
Dependent Claim
107 words
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.
Claim 3
Dependent Claim
25 words
A cable according to claim 1 further comprising a rivet electrically coupled to said line and fixedly attached through said proximal end of said substrate.
Claim 4
Dependent Claim
21 words
A cable according to claim 2 further comprising a connector sealingly coupled to said substrate and electrically coupled to said rivet.
Claim 5
Dependent Claim
32 words
A body implantable cable according to claim 1, 2, or 3 wherein said first portion of said first surface contains approximately the same area as said second portion of said first surface.
Claim 6
Dependent Claim
49 words

Claim 7
Independent Claim
52 words
An apparatus for implantation in the body of an animal comprising: a. a flexible insulative substrate having a first folded surface; b. a conductive path of conductive ink fixedly attached to said first folded surface; and c. means for sealing said conductive path on said folded surface from body fluids and tissue.
Claim 8
Independent Claim
52 words
An apparatus for implantation in the body of an animal comprising: a. a flexible insulative substrate having a first folded surface; b. a conductive path of conductive ink fixedly attached to said first folded surface; and c. means for sealing said conductive path on said folded surface from body fluids and tissue.
Claim 9
Dependent Claim
45 words
An apparatus according to claim 6 wherein said first folded surface has a first edge and said sealing means a second edge and further comprising means coupled to said first edge and said second edge for sealingly coupling said first edge to said second edge.
