ELECTRICAL STIMULATION LEADS AND SYSTEMS WITH ANCHORING UNITS HAVING STRUTS AND METHODS OF MAKING AND USING

摘要

An anchoring unit is disposed on a lead body of an electrical stimulation lead. The anchoring unit has a first end and a second end and includes a first attachment ring disposed at the first end, a second attachment ring disposed at the second end, and longitudinal struts extending linearly between, and coupled to, the first and second attachment rings. At least a portion of each longitudinal strut rests against the lead body in a retracted position, and each anchoring unit has a deployed position in which the first and second attachment rings are positioned closer together with the longitudinal struts extending away from the lead body to contact patient tissue and anchor the lead within the patient tissue.

主权项

1. An electrical stimulation lead, comprising:
a lead body having a distal end portion and a proximal end portion; a plurality of electrodes disposed along the distal end portion of the lead body; a plurality of terminals disposed along the proximal end portion of the lead body; a plurality of conductors disposed within the lead body, each conductor of the plurality of conductors electrically coupling each of the plurality of terminals to at least one of the plurality of electrodes; and an anchoring unit disposed along the distal end portion of the lead body, the anchoring unit having a first end and a second end and comprising
a first attachment ring disposed at the first end,a second attachment ring disposed at the second end, anda plurality of longitudinal struts extending linearly between, and coupled to, the first and second attachment rings, wherein at least a portion of each longitudinal strut rests against the lead body in a retracted position, and each anchoring unit is configured and arranged to have a deployed position in which the first and second attachment rings are positioned closer together with the longitudinal struts extending away from the lead body to contact patient tissue and anchor the lead within the patient tissue.
