Abstract:
1. An implantable medical system comprising: a medical lead including an insulating sheath and a conductor; and an anchoring device defining an inner lumen adapted to coaxially receive the medical lead, the inner lumen having an effective diameter, the anchoring device including: a sleeve including a substantially elongate, elastomeric body defining an outer surface, the inner lumen extending through the sleeve; and a compression member including a first end, a second end, and an intermediate portion between the first and second ends, the compression member being at least partially embedded in the sleeve such that compression of the first and second ends of the compression member toward one another causes the effective diameter of at least a portion of the inner lumen extending through the sleeve of the anchoring device to reversibly increase in order to permit the anchoring device to slide relative to the lead, wherein the compression member includes a first collar, a second collar, and a plurality of substantially arcuate bands extending between the first and second collars, and each of the first and second collars project radially outward from the outer surface of the sleeve.
