Abstract
Abstract A pacing lead for a cardiac stimulator that includes an elongated flexible insulating lead body. An electrode is attached to the lead body at its distal end. An elongated conductor extends through a lumen of the elongated lead body for connecting the electrode to the terminal pin. The conductor is in the form of a coiled wire until it reaches approximate the electrode. It is then crimped to a cable conductor which in turn is crimped or welded to the electrode. The electrode is supported at the distal end by a molded support body which includes a lumen for a guide wire.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
136 words
A pacing lead for a cardiac stimulator, said pacing lead comprising: a) an elongated flexible insulating lead body having a proximal end, a distal end and a lumen extending therebetween; b) an electrode attached to the lead body at its distal end; c) coupling means attached to the proximal end for coupling said electrode to said cardiac stimulator; d) an elongated, helically wound conductor having a proximal end and distal end, and a flexible conductor cable disposed in the lumen for connecting the electrode to the coupling means, the helically wound conductor defining a removable stylet receiving lumen, the distal end of the helically wound conductor being joined to the flexible conductor cable; and e) a guide wire lumen positioned approximate said distal end of said lead body and adapted to receive a guide wire therethrough.
Claim 2
Dependent Claim
136 words
A pacing lead for a cardiac stimulator, said pacing lead comprising: a) an elongated flexible insulating lead body having a proximal end, a distal end and a lumen extending therebetween; b) an electrode attached to the lead body at its distal end; c) coupling means attached to the proximal end for coupling said electrode to said cardiac stimulator; d) an elongated, helically wound conductor having a proximal end and distal end, and a flexible conductor cable disposed in the lumen for connecting the electrode to the coupling means, the helically wound conductor defining a removable stylet receiving lumen, the distal end of the helically wound conductor being joined to the flexible conductor cable; and e) a guide wire lumen positioned approximate said distal end of said lead body and adapted to receive a guide wire therethrough.
Claim 3
Dependent Claim
16 words
A pacing lead of claim 1 wherein said conductor cable is operatively coupled to said electrode.
Claim 4
Dependent Claim
46 words
A pacing lead of claim 1 and further including an electrode support at said distal end of said elongated lead body, said electrode support including said guide wire lumen with an insulating layer isolating said electrode from said guide wire extending through the guide wire lumen.
Claim 5
Dependent Claim
14 words
A pacing lead of claim 1 wherein said coupling means is a terminal pin.
Claim 6
Dependent Claim
132 words
A pacing lead for a cardiac stimulator, said pacing lead comprising: a) an elongated flexible insulating lead body having a proximal end, a distal end and a lumen extending therebetween, said lead body dimension to be passed through the great coronary vein; b) an electrode attached to the lead body at its distal end; c) a terminal pin attached to the lead body at its proximal end; d) an elongated spiral wound conductor and a flexible conductor cable disposed in the lumen and connected in series relation for coupling the electrode to the terminal pin, the spiral wound conductor being proximal of the flexible conductor cable and defining a further lumen for receiving a removable stylet therein; and e) a guide wire lumen positioned approximate said distal end of said lead body.
