PRE-SELECTED COMPRESSION LEAD ANCHORING DEVICE
First Claim
1. An implantable medical system comprising:
- a medical lead;
an anchoring device received coaxially over the medical lead, the anchoring device including;
an elastomeric sleeve having a substantially elongate, hollow, and tubular body; and
a compression governor coaxially secured about the elastomeric sleeve, the compression governor adapted to limit compressive forces exerted on the lead by the anchoring device at a predetermined limit and provide a visual indicator that the predetermined limit has been reached; and
at least one fastener secured circumferentially about the anchoring device to cause compression of the anchoring device on the medical lead.

Abstract
An implantable medical system for anchoring a medical lead implanted in a patient includes a medical lead, an anchoring device received coaxially over the medical lead, and at least one fastener secured circumferentially about the anchoring device to cause compression of the anchoring device on the medical lead. The anchoring device includes an elastomeric sleeve having a substantially elongate, hollow, and tubular body and a compression governor coaxially secured about the elastomeric sleeve. The compression governor is adapted to limit compressive forces exerted on the lead by the anchoring device at a predetermined limit and provides a visual indicator that the predetermined limit has been reached.

9. An anchoring device for anchoring a medical lead implanted in a patient, the anchoring device comprising:
-
a sleeve having an elongate, hollow, and tubular shape, the sleeve further having an outer surface with at least one circumferential recessed area formed therein and a central bore adapted to slidably receive the medical lead; a compression governor that is coaxially fitted about the sleeve in the recessed area and substantially less compliant than the sleeve, the compression governor having an outer surface, at least one circumferentially disposed groove formed partially into the outer surface, and at least one window in the compression governor positioned at least partially in the groove. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method of limiting compression of an anchoring device on a medical lead, the method comprising:
-
coaxially receiving a medical lead within the anchoring device, the anchoring device having a groove for receiving a fastener and comprising; a sleeve having an elongate, hollow, and tubular shape, and a bore for receiving the lead; a compression governor that is coaxially fitted about the sleeve in the recessed area and that is substantially less compliant than the sleeve, the compression governor having a window through the sleeve and being adapted to limit compressive force on the lead to a predetermined maximum compressive force; tying a fastener about the groove to compress the anchoring device onto the lead with the maximum compressive force; and providing a visual indicator that the maximum compressive force has been reached using the window of the compressive sleeve. - View Dependent Claims (16, 17, 18, 19, 20)
