COMPLIANT ELECTRICAL STIMULATION LEADS AND METHODS OF FABRICATION

摘要

In one embodiment, a neurostimulation lead (100) for stimulating neural tissue of a patient, comprises: a lead body (106) of insulative material; a plurality of electrodes (110); a plurality of terminals (114); a plurality of conductors (201), wherein the plurality of electrodes are electrically coupled to the plurality of terminals through the plurality of conductors; wherein the plurality of conductors are disposed in a helical manner in a repeating pattern of groups of conductors separated by gaps (204) along a substantial length of the lead body, each gap being larger than an inter-conductor pitch within the groups of conductors; wherein the insulative material is a compliant material permitting elongation of the lead at low stretching forces and the insulative material of the lead body is fused through a substantial volume of the lead body and along a substantial length of the lead body.
