Paddle leads having asymmetric electrode configurations

摘要

Various embodiments concern an implantable lead. The lead can comprise a lead body. At least two conductors can extend within the lead body, such as in respective lumens of the lead body. The lead can comprise at least two electrodes. Each electrode can be connected to a respective one of the at least two conductors. A paddle body can be connected to the lead body. The paddle body can comprise a longitudinal axis that divides the paddle body into left and right sides. The at least two electrodes can be partially embedded within the paddle body. The at least two electrodes can be arrayed along the longitudinal axis. Each electrode can be asymmetric about the longitudinal axis.

1. An implantable lead comprising:
a lead body; at least two conductors extending within the lead body; at least two electrodes, each electrode comprising a main body and a stem portion that is offset from a center of the main body, a first electrode of the at least two electrodes located distally of a second electrode of the at least two electrodes, each stem portion of each electrode connected to a respective one of the at least two conductors; and a paddle body formed by a polymeric material, each of the at least two electrodes mounted on the paddle body, wherein the center of each of the main bodies is centered on a longitudinal axis of the paddle body, the longitudinal axis dividing the paddle body laterally into left and right halves, the stem portion of the first electrode located mostly or entirely on one of the right half or the left half of the paddle body, and the stem portion of the second electrode is located mostly or entirely on another of the right half or the left half of the paddle body, and the at least two conductors do not bend or curve within the paddle body, wherein the at least two conductors extend in a parallel, non-coaxial arrangement within the lead body and from the lead body to a proximal one of the at least two electrodes.
