Patent ID: 8332049

Claim:
A multi-lead system comprising: a first lead comprising a first lead body having a distal end, a proximal end, a longitudinal length, and an outer surface, a first plurality of electrodes disposed along the distal end of the first lead with the first plurality of electrodes arranged along a first electrode axis, a first plurality of terminals disposed along the proximal end of the first lead, a first stylet lumen extending along the longitudinal length of the first lead body from the proximal end to the distal end of the first lead body, a first outlet port defined distally from the first plurality of electrodes, the first outlet port providing an opening between the first stylet lumen and the outer surface of the first lead body, and a first plurality of conductor wires extending along the first lead and coupling the first plurality of electrodes electrically to the first plurality of terminals; a second lead comprising a second lead body having a distal end, a proximal end, and at least one bend formed between the distal end and the proximal end of the second lead body, a second plurality of electrodes disposed along the distal end of the second lead with the second plurality of electrodes arranged along a second electrode axis, a second plurality of terminals disposed along the proximal end of the second lead, and a second stylet lumen extending distally along the second lead body from a second inlet port defined in the at least one bend, a second plurality of conductor wires extending along the second lead and coupling the second plurality of electrodes electrically to the second plurality of terminals; and a stylet configured and arranged for concurrent insertion into both the first stylet lumen and the second stylet lumen with the stylet extending between the first stylet lumen and the second stylet lumen via the first outlet port and the second inlet port, wherein when the stylet is inserted into both the first stylet lumen and the second stylet lumen the first electrode axis is aligned linearly with the second electrode axis to form a combination electrode axis, the combination electrode axis comprising each electrode of the first plurality of electrodes and each electrode of the second plurality of electrodes aligned along a common axis.
