Suture sleeve with structure for enhancing pacing lead gripping
First Claim
1. A suture sleeve assembly comprising a suture sleeve made of soft elastomeric material and means associated with the suture sleeve for enhancing gripping of a lead body by the suture sleeve, said suture sleeve comprising a tubular sleeve having a throughbore adapted to receive a pacing lead body and two spaced apart outer annular suture receiving grooves each adapted to receive a suture therein to fix said assembly to a pacing lead, said gripping enhancing means being made of a material which is different than the material of the suture sleeve and which is stiff but flexible, and said gripping enhancing means being positioned to extend within and longitudinally of an elongate axis of said suture sleeve in the area of and between said annular grooves thereby to disperse any stress placed upon said suture sleeve when sutures are tied in said annular grooves, and said suture sleeve assembly being radially compressible upon the placement and tying of a suture around said suture sleeve assembly in each annular groove to facilitate generally uniform gripping of the lead body by said suture sleeve assembly along the length of said gripping enhancing means.

Abstract
A suture sleeve and associated gripping enhancing structure which extend longitudinally of an elongate axis of the suture sleeve which has a lumen therein and received over a lead body of a pacing lead. The gripping enhancing structure is radially compressible with the suture sleeve upon the tying of sutures around the suture sleeve to facilitate gripping of the lead body by the suture sleeve and/or gripping enhancing means. The gripping enhancing structure can be formed within and integral with the suture sleeve, or can be a separate thermoplastic part which is insert molded into the suture or which is received on and around the suture sleeve.

22. A suture sleeve assembly comprising a suture sleeve made of soft elastomeric material and means associated with the suture sleeve for enhancing gripping of a lead body by the suture sleeve, said suture sleeve comprising a tubular sleeve having a throughbore adapted to receive a pacing lead body and two spaced apart outer annular suture receiving grooves each adapted to receive a suture therein to fix said assembly to a pacing lead, said gripping enhancing means being made of a material which is identical to the material of the suture sleeve, said gripping enhancing means being located in the area beneath said annular grooves and said suture sleeve assembly being radially compressible upon the placement and tying of a suture around said suture sleeve assembly in each annular groove to facilitate generally uniform gripping of the lead body by said gripping enhancing means of said suture sleeve assembly.
- 23. A suture sleeve assembly comprising a suture sleeve made of soft elastomeric material and means associated with the suture sleeve for enhancing gripping of a lead body by the suture sleeve, said suture sleeve having a throughbore which is adapted to receive a pacing lead body, said gripping enhancing means comprising a C-shaped sleeve that is made of a material which is different than the material of the suture sleeve and which is stiff but flexible, said C-shaped sleeve being received around the outer surface of said suture sleeve and having two spaced apart outer, partially annular, suture receiving grooves each adapted to receive a suture therein to fix said assembly to a pacing lead, said C-shaped sleeve being positioned to extend longitudinally of an elongate axis of said suture sleeve thereby to disperse any stress placed upon said suture sleeve when sutures are tied in said partially annular grooves, and said suture sleeve assembly being radially compressible upon the placement and tying of a suture around said suture sleeve assembly in each annular groove to facilitate generally uniform gripping of the lead body by said suture sleeve assembly alon the length of said C-shaped sleeve.
