Multiple lead suture sleeve
First Claim
1. A suture sleeve for anchoring the leads adapted to be used with an implantable medical device, the sleeve including flexible side walls and transversely spaced apart, longitudinally extending lead receiving channels, at least a portion of the length of said walls having confronting, spaced apart edges defining a longitudinally extending opening, the exterior surface of said portion of said wall having at least one groove extending about the outer surface in a generally transverse plane, the sleeve being adapted to receive the leads through the longitudinal opening defined by the spaced apart edges of the side walls, whereby a suture placed and tied in each of said at least one groove compresses said sleeve about said leads in gripping relationship therewith, thereby bringing said confronting edges into engagement thereby preventing further compression of said sleeve to prevent damage to the leads.

Abstract
A suture sleeve for securing the leads of a multiple lead implantable medical device includes lead gripping and anchoring portions. The sleeve has a pair of flexible side walls and longitudinally extending channels for receiving the leads. The side walls of at least the gripping portion have longitudinally extending, confronting, spaced apart edges and comprises two layers one of which is formed of a soft plastic such as silicone and the other of which is formed of a harder but flexible material such as polysulfone. Sutures placed and tied about the gripping portion compress the sleeve about the leads. Tightening of the sutures brings the confronting edges of the gripping portion of the sleeve into engagement thereby precluding further compression of the sleeve and preventing damage to the leads.

- 1. A suture sleeve for anchoring the leads adapted to be used with an implantable medical device, the sleeve including flexible side walls and transversely spaced apart, longitudinally extending lead receiving channels, at least a portion of the length of said walls having confronting, spaced apart edges defining a longitudinally extending opening, the exterior surface of said portion of said wall having at least one groove extending about the outer surface in a generally transverse plane, the sleeve being adapted to receive the leads through the longitudinal opening defined by the spaced apart edges of the side walls, whereby a suture placed and tied in each of said at least one groove compresses said sleeve about said leads in gripping relationship therewith, thereby bringing said confronting edges into engagement thereby preventing further compression of said sleeve to prevent damage to the leads.
- 6. A suture sleeve for securing the leads of a dual lead implantable medical device, the sleeve having a generally double C-shaped cross section including a pair of curved side walls and a pair of transversely spaced apart, lead receiving arcuate channels, a portion of the length of said walls having confronting, spaced apart edges defining a longitudinally extending opening, the exterior surface of said portion having a plurality of grooves, each groove extending about the outer surface in a generally transverse plane, the sleeve being adapted to receive the leads through the longitudinal opening defined by the edges of the side walls, whereby sutures placed and tied in said grooves compress said sleeve about said leads in gripping relationship therewith, thereby bringing said confronting edges into engagement thereby preventing further compression of said sleeve to prevent damage to the leads.
- 11. An elongated suture sleeve for securing the lead means of a cardiac pacemaker, the lead means comprising at least two leads, the sleeve including a longitudinally extending channel for receiving each lead, the channels being spaced apart transvenously, the sleeve having a side wall with an interior surface for gripping the lead means and suture receiving means extending about the sleeve, at least the portion of the length of the sleeve having the suture receiving means comprising two layers, one of the layers being of flexible material harder than the material of the other layer and having confronting, spaced apart edges, said confronting edges being so spaced as to be brought into engagement in response to placement and tying of suture means in said suture receiving means to thereby limit compression of the sleeve to prevent damage to the lead means.
-
15. An elastomeric suture sleeve for securing the leads of a multiple lead implantable medical device, the sleeve defining longitudinally extending lead receiving channels, the exterior surface of said wall having at least one groove extending about the outer surface in a generally transverse plane, whereby a suture placed and tied in said at least one groove compresses said sleeve about said leads in gripping relationship therewith, said sleeve including means for anchoring the sleeve to surrounding tissue.
