Protective, visible suture sleeve for anchoring transvenous lead bodies
First Claim
1. A suture sleeve for anchoring a lead body of an implantable stimulation lead, the implantable stimulation lead have at least one conductor insulated within the lead body, comprising:
- a tubular body having an interior and an exterior surface, the interior surface defining a longitudinal bore dimensioned to receive the lead body of the implantable stimulation lead, the exterior surface having at least one annular, suture-receiving groove, the tubular body being formed of biocompatible polymeric material with a predetermined amount of radiologically dense powder dispersed therein so as to present a clear fluoroscopic image, whereby the sleeve can be fluoroscopically located on the lead body.

Abstract
A suture sleeve for anchoring the lead body of an implantable medical device is fabricated of a biocompatible, polymeric material to which has been added color pigment in clear contrast with the bodily tissue adjacent the sleeve. The sleeve is therefore readily visible to the naked eye to aid the physician in locating the sleeve during lead implant or lead revision. Furthermore, the tubular body may be radiopaque and, therefore, easily seen on a fluoroscope through the addition of a radiologically dense material, such as tantalum powder, to the plastic from which the sleeve is molded.

8. A suture sleeve for anchoring a implantable stimulation lead, the implantable stimulation lead having a conductor coil therein, the suture sleeve comprising:
-
a tubular body having an interior and an exterior surface, the interior surface defining a longitudinal bore dimensioned to receive the lead body of the implantable stimulation lead, the exterior surface having at least one annular, suture-receiving groove, the tubular body being formed of a radiopaque, biocompatible polymeric material so as to present a clear fluoroscopic image without being so dark that it occludes the conductor coil within the sleeve; whereby the sleeve can be fluoroscopically located on the lead body and the integrity of the conductor coil received within the suture sleeve can be verified after the lead body is tied down.

9. A suture sleeve for anchoring a lead body of an implantable stimulation lead to body tissue, the implantable stimulation lead having a conductor coil insulated within the lead body, comprising:
-
a tubular body having an interior and an exterior surface, the interior surface having means for receiving the lead body of the implantable stimulation lead; and securing means, on the exterior surface of the tubular body, for securing the tubular body to selected body tissue; wherein the tubular body is molded of a radiopaque, biocompatible polymeric material so as to present a clear fluoroscopic image for locating the tubular body on the stimulation lead in the body tissue. - View Dependent Claims (10)

11. A suture sleeve for anchoring a lead body of an implantable stimulation lead to body tissue, comprising:
-
a tubular body having an interior and an exterior surface, the interior surface having means for receiving the lead body of the implantable stimulation lead; and securing means, on the exterior surface of the tubular body, for securing the tubular body to selected body tissue; wherein the tubular body is molded of a pigmented, biocompatible polymeric material which contrasts with that of adjacent body tissue for locating the tubular body along the stimulation lead in the body tissue.
