Abstract:
1. An implantable medical device operable to provide a therapy comprising: a lead having a proximal end, a distal end, a body that includes at least one outer conductive member and a multilumen member that extends from the proximal end to the distal end; a first electrode fixedly coupled between the proximal end and the distal end of the lead, the first electrode in electrical communication with a first inner conductor disposed within the multilumen member to deliver a therapy, the first electrode in electrical communication with and directly coupled to the at least one outer conductive member and having a first surface area; a second electrode coupled to the distal end of the lead, the second electrode in electrical communication with a second inner conductor disposed within the multilumen member to deliver a therapy, the second electrode having a second surface area; and wherein the first surface area being greater than the second surface area and the first electrode dissipates a current induced in the at least one outer conductive member.
