Abstract
Abstract A temporary atrial defibrillation lead featuring a polytetraflouroethylene ("TEFLON") felt pad 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 are 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 polytetraflouroethylene ("TEFLON") 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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
79 words
A temporary medical electrical lead comprising: a pad having at least one hole; and a member, the member comprising a conductor having a distal region and a proximal region and an insulative sleeve covering the proximal region of conductor, the distal region of the conductor mounted within the pad in a position in which the member intersects the at least one hole, the distal region of the conductor having a means for temporarily affixing the conductor to the pad.
Claim 2
Dependent Claim
79 words
A temporary medical electrical lead comprising: a pad having at least one hole; and a member, the member comprising a conductor having a distal region and a proximal region and an insulative sleeve covering the proximal region of conductor, the distal region of the conductor mounted within the pad in a position in which the member intersects the at least one hole, the distal region of the conductor having a means for temporarily affixing the conductor to the pad.
Claim 3
Dependent Claim
