Suture sleeve assembly
First Claim
1. A suture sleeve assembly for placement around an elongated lead body, to anchor said lead body in position relative to the adjacent tissue, which comprises:
- a tubular sleeve having a bore;
a collet member, said collet member defining a plurality of axially extending legs residing in the bore of the tubular sleeve, said legs having inner surfaces, the inner surfaces of said legs defining frictional gripping members to engage a lead body positioned within said sleeve assembly; and
means for retaining said collet member in a position with said legs occupying the bore of the tubular sleeve;
said retaining means including outwardly extending hook members defined on the collet member adjacent the free ends of said legs, and a retention flange on the end of said collet member opposed to said free ends, said tubular sleeve being proportioned to that the legs pass through said sleeve to permit the hook members to engage one end thereof, while the retention flange engages the other end of said sleeve.

Abstract
A suture sleeve assembly is provided for placement around an elongated lead body, for example a cardiac pacing lead. The assembly anchors the lead body in position relative to the adjacent tissue, and comprises a tubular sleeve and a collet member. The collet member defines a plurality of axially extending legs residing in the bore of the tubular sleeve. The inner surfaces of the legs define frictional gripping members to engage a lead body positioned within the sleeve assembly. Structure is also provided for retaining the collet member in a position with the legs occupying the bore of the tubular sleeve.

1. A suture sleeve assembly for placement around an elongated lead body, to anchor said lead body in position relative to the adjacent tissue, which comprises:
-
a tubular sleeve having a bore; a collet member, said collet member defining a plurality of axially extending legs residing in the bore of the tubular sleeve, said legs having inner surfaces, the inner surfaces of said legs defining frictional gripping members to engage a lead body positioned within said sleeve assembly; and
means for retaining said collet member in a position with said legs occupying the bore of the tubular sleeve;
said retaining means including outwardly extending hook members defined on the collet member adjacent the free ends of said legs, and a retention flange on the end of said collet member opposed to said free ends, said tubular sleeve being proportioned to that the legs pass through said sleeve to permit the hook members to engage one end thereof, while the retention flange engages the other end of said sleeve. - View Dependent Claims (2, 3)

4. A suture sleeve assembly for placement around an elongated lead body to anchor said lead body in position relative to the adjacent tissue, which comprises:
-
a tubular sleeve having a bore, said tubular sleeve having an outer surface and defining suture-receiving channel means on its outer surface to facilitate its retention in position by suture; a collet member, said collet member defining a plurality of axially extending legs residing in the bore of the tubular sleeve, said legs having inner surfaces, the inner surfaces of said legs defining frictional gripping members to engage a lead body positioned within said sleeve assembly, said collet member defining outwardly extending hook members adjacent the free ends of said legs, and a retention flange on the end of said collet member opposed to said free ends, said tubular sleeve being proportioned whereby the legs pass through said sleeve to permit the hook members to engage one end thereof while the retention flange engages the other end of said sleeve, to retain the collet member precisely positioned with respect to said sleeve. - View Dependent Claims (5, 6)
