Abstract

An electrical stimulation lead includes a lead body with electrodes disposed along the distal end portion of the lead body and terminals disposed along the proximal end portion of the lead body. Conductors electrically couple the terminals to the electrodes. A contact assembly is disposed at one of the proximal end portion or the distal end portion of the lead body. The contact assembly is formed from a shaped mesh and includes annular grooves defined along an outer surface of the shaped mesh; and a stylet tube disposed in a contact assembly lumen. Each of the conductors extends along at least a portion of the shaped mesh within the contact assembly lumen and external to the stylet tube. For each of the annular grooves, one of the electrodes or one of the terminals is disposed in the annular groove.
