Patent ID: 8244375

Claim:
An implantable medical lead comprising: a first helically wound conductor coil extending between a proximal end and a distal end of the implantable lead; a second helically wound conductor coil extending between the proximal and distal ends; a ring electrode near the distal end and electrically coupled to the first coil; a tip electrode near the distal end, distal of the ring electrode, and electrically coupled to the second coil, wherein the second helically wound coil extends about the first helically wound coil for a first portion of the medical lead between the proximal end of the implantable lead and the ring electrode; and a distal transition near the distal end of the lead wherein as the first and second helically wound coils extend distally, the first helically wound coil transitions from being inside the second helically wound coil to being outside the second helically wound coil.
