ANCHORING UNITS FOR IMPLANTABLE ELECTRICAL STIMULATION SYSTEMS AND METHODS OF MAKING AND USING

摘要

An anchoring unit for an implantable lead includes a body, a plurality of anchoring members, and at least one connecting element coupling together at least two of the anchoring members that are positioned adjacent to one another. The body is configured and arranged for positioning along a portion of an outer surface of a lead. The body has a first end, a second end, and a longitudinal axis extending therebetween. The first end is configured and arranged for placement on the lead so that the first end is positioned more distally on the lead than the second end. Each anchoring member has a proximal end and a distal end. The proximal end of each anchoring member extends from the body and the distal end of each anchoring member anchors to patient tissue upon implantation of the anchoring unit into the patient.

主权项

1. An implantable lead, comprising:
a lead body having a proximal end portion, a distal end portion, and an outer surface; 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; a plurality of conductors electrically coupling the electrodes to the terminals; and at least one anchoring unit disposed along the lead body, each of the at least one anchoring unit comprising
a body configured and arranged for positioning along a portion of the outer surface of the lead body, the body having a first end and a second end and a longitudinal axis extending therebetween, the first end being configured and arranged for placement on the lead body so that the first end is positioned more distally on the lead than the second end; anda plurality of anchoring members extending from the body of the anchoring unit and away from the lead body, each anchoring member having a proximal end and a distal end, the proximal end of each anchoring member coupled to the body and the distal end of each anchoring member configured and arranged for extending into tissue of a patient to anchor the anchoring unit to the tissue of the patient upon implantation of the implantable lead into the patient;wherein each of the plurality of anchoring members is configured and arranged to fold flat when the lead is inserted into a cannula.
