Systems and methods for making and using a trial stimulation system having an electrical connector disposed on a trial stimulation lead

A trial stimulation lead assembly for providing electrical stimulation of patient tissue during a trial stimulation, the trial stimulation lead assembly comprising:

• a trial stimulation lead configured and arranged for insertion into a patient, the trial stimulation lead comprising
• an elongated lead body having a length, a circumference, and a longitudinal axis defined by a proximal end and a distal end,
• a plurality of electrodes disposed at the distal end of the lead body,
• an electrical connector disposed at the proximal end of the lead body, the electrical connector comprising an outer case and a contact array disposed along the outer case, wherein the contact array extends transversely to the longitudinal axis of the lead body,
• a plurality of electrical conductors extending along the length of the lead body and coupling each of the plurality of electrodes to at least one of the plurality of contacts, and
• a lumen extending along at least a portion of the length of the lead body.
