Patent ID: 8249719

Claim:
An anchoring device for anchoring a medical lead implanted in a patient, the anchoring device comprising: a substantially elongate, hollow, tubular, and elastically compressible body, the body having a longitudinal axis; a suture groove formed circumferentially about the tubular body for receiving a suture; and an inner bore extending through the tubular body and configured to accommodate a medical lead extending through the inner bore, the inner bore forming a recessed portion having an inner bore diameter, and a surrounding portion having an inner bore diameter adjacent the recessed portion, the recessed portion having an inner surface area having a friction enhancing characteristic relative to the surrounding portion; wherein the recessed portion has a relaxed configuration in which the inner bore diameter of the recessed portion is greater than the inner bore diameter of the surrounding portion and that permits the anchoring device to be slid onto the medical lead and a contact configuration in which the inner surface area of the recessed portion is configured to frictionally engage the medical lead so as to secure the medical lead relative to the anchoring device, the recessed portion moving from the relaxed configuration to the contact configuration in response to a compressive force applied via a suture disposed within the suture groove.
