COMPRESSION CONTROL LEAD ANCHORING DEVICE
First Claim
1. An implanted 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 substantially more rigid than the elastomeric sleeve coaxially secured to the elastomeric sleeve, the compression governor defining an inner bore having an effective diameter, the compression governor being adapted to limit compression at a pre-selected minimum effective diameter to limit compressive forces exerted on the medical lead by the anchoring device; and
at least one fastener secured circumferentially about the anchoring device to cause compression of the anchoring device on the medical lead.

Abstract
An implanted medical system includes a medical lead, an anchoring device and at least one suture secured circumferentially about the anchoring device to cause compression of the anchoring device on the medical lead. In particular, the anchoring device is received coaxially over the medical lead and includes an elastomeric sleeve and a compression governor. The elastomeric sleeve has a substantially elongate, hollow, and tubular body. The compression governor is substantially more rigid than the elastomeric sleeve and is coaxially secured to the elastomeric sleeve. The compression governor defines an inner bore having an effective diameter and is adapted to limit compression at a pre-selected minimum effective diameter to limit compressive forces exerted on the lead by the anchoring device.

13. An anchoring device for a medical lead, the anchoring device comprising:
-
a sleeve having an elongate, tubular shape, the sleeve having an outer surface with at least one circumferential groove formed therein and a central bore adapted to slidably receive the medical lead; and a compression governor coaxially fitted within the sleeve and substantially less compliant than the sleeve, the compression governor being substantially C-shaped in transverse cross-section with a slit formed in a longitudinal direction along the compression governor to define first and second opposing edges; wherein the compression governor is adapted to compress from an open state the first and second edges being substantially separated from one another and a closed state with the first and second edges in at least partial contact. - View Dependent Claims (14, 15, 16, 17)

18. A method of securing a medical lead in a body, the method comprising:
-
providing an anchoring device having an inner bore and including a tubular sleeve formed of a substantially compressible material and a compression governor having a substantially C-shaped cross section and adapted to limit radial compression of the anchoring device; coaxially receiving the medical lead in the inner bore of the anchoring device; tying a suture about the anchoring device to compress the anchoring device onto the medical lead; and tightening the suture until applied a compression force applied to the medical lead is restricted by the compression governor of the anchoring device. - View Dependent Claims (19, 20)
