Abstract
Devices and methods for providing neurostimulation to a patient, particularly in trial systems assessing suitability of a permanently implanted neurostimulation, are provided herein. In one aspect, a trial neurostimulation lead includes a coiled conductor coupled to a proximal contact connector having a retention flange that withstands tensile force from tension in the lead so as to maintain the electrical connection during a trial period. In another aspect, a trial neurostimulation system includes a lead extension that includes a regression stopper between the implanted distal connector and proximal lead disposed outside the body to prevent regression of the lead through a secondary incision, thereby preventing infection and facilitating explant of the system. Methods of assembling and utilizing such leads and systems are detailed herein.
