Abstract

Abstract A temporary atrial defibrillation lead featuring a pad fashioned of a pliant biocompatible material in which three parallel stainless steel defibrillation wire electrodes are mounted. The pad contains holes which expose the electrode wires in a discontinuous fashion. The three electrode wires are merged into one polyurethane insulated lead body, proximal to the pad. At the proximal end of the lead body a stainless steel connector pin with break away needle is mounted, for percutaneous exteriorization of the lead pin, in an area separated from the surgical incision. The break away needle can be broken off to make the connector pin suitable to patient cable connection. The pad is permanently implanted on the atria and remains implanted after removal of the temporary electrode sections. The temporary electrode sections may be removed by gently pulling them at their proximal end. In a preferred embodiment the pad is fashioned of PTFE felt. In an alternate embodiment the pad is fashioned of collagen and is thereby absorbed by the body tissues over time.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 72 words
A temporary medical electrical lead comprising: a mounting pad of a pliant biocompatible material; at least one elongate member attached to said mounting pad, said member comprising a conductor and an insulative sleeve, said conductor having a distal region and a proximal region, said insulative sleeve covering said proximal region of said conductor, characterized in that said distal region of said conductor has means for temporarily affixing the conductor to said pad.
Claim 2
Dependent Claim 72 words
A temporary medical electrical lead comprising: a mounting pad of a pliant biocompatible material; at least one elongate member attached to said mounting pad, said member comprising a conductor and an insulative sleeve, said conductor having a distal region and a proximal region, said insulative sleeve covering said proximal region of said conductor, characterized in that said distal region of said conductor has means for temporarily affixing the conductor to said pad.
Claim 3
Dependent Claim 22 words
A temporary medical electrical lead according to claim 1 wherein said at least one elongate member comprises a plurality of elongate members.
Claim 4
Dependent Claim 19 words
A temporary medical electrical lead according to claim 1 wherein said pad (33) has a series of holes (34).
Claim 5
Dependent Claim 33 words
A temporary medical electrical lead according to claim 3 wherein said elongate member is mounted within said pad (33) in a position in which it intersects at least one of said holes (34).
Claim 6
Dependent Claim 29 words
A temporary medical electrical lead according to claim 1 further comprising said means for temporarily affixing are fastened to said conductor at a point proximal within said distal region.
Claim 7
Dependent Claim 26 words
A temporary medical electrical lead according to claim 1 further comprising a plurality of elongate members, said elongate members mounted within said pad (33) in parallel.
Claim 8
Dependent Claim 15 words
A temporary medical electrical lead according to claim 1 wherein said pad (33) is porous.
Claim 9
Dependent Claim 16 words
A temporary medical electrical lead according to claim 1 wherein said pad (33) is PTFE felt.
Claim 10
Dependent Claim 15 words
A temporary medical electrical lead according to claim 1 wherein said pad (33) is collagen.
Claim 11
Dependent Claim 17 words
A temporary medical electrical lead according to claim 1 wherein said conductor (21) is a stranded wire.
Claim 12
Dependent Claim 25 words
A temporary medical electrical lead according to claim 1 further comprising said proximal end of said elongate conductor is attached to a connector pin assembly.
Claim 13
Dependent Claim 21 words
A temporary medical electrical lead according to claim 1 further comprising a needle (11) attached to said connector pin assembly (4).
Claim 14
Dependent Claim 33 words
A temporary medical electrical lead according to claim 1 wherein said distal region of said conductor is alternatingly positioned in and out of said pad whereby said conductor is woven through said pad.
