SYSTEMS AND METHODS FOR MAKING AND USING ANCHORING ARRANGEMENTS FOR LEADS OF ELECTRICAL STIMULATION SYSTEMS

摘要

A lead assembly includes an electrical stimulation lead with a lead body having a distal portion, a proximal portion, a longitudinal length, and an outer surface. At least one electrode is disposed along the distal portion of the lead body. At least one terminal is disposed along the proximal portion of the lead body. At least one lead conductor electrically couples the at least one electrode to the at least one terminal. An anchoring arrangement is configured and arranged to reduce undesired movement of the lead relative to a patient when the lead is inserted into the patient. The anchoring arrangement includes at least one helical member attached to, and projecting outwardly from, the outer surface of the lead. The at least one helical member extends along at least 30% of the longitudinal length of the lead and makes at least one full coil around the lead.
