Suture sleeve assembly

Claim 2

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.

Claim 3

The suture sleeve assembly of claim 1 in which said tubular sleeve is made of elastomeric material, and said collet member is made of generally rigid material having sufficient flexibility whereby said legs can be forced by bending into frictionally engaging relation with a lead passing through said collet member.

Claim 4

The suture sleeve assembly of claim 1 in which the bore of said tubular sleeve is proportioned to bias said axially extending legs inwardly when the legs occupy the bore of said tubular sleeve, whereby an elongated lead body may be threaded through said collet member, and said axially extending legs may be forced inwardly by the bore of said tubular sleeve to engage said lead body by assembling the tubular sleeve and collet member after said tubular sleeve has been positioned at a predetermined position on said lead body.

Claim 5

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.

Claim 6

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.

Claim 7

The suture sleeve assembly of claim 4 in which said tubular sleeve is made of elastomeric material, and said collet member is made of generally rigid material having sufficient flexibility whereby said legs can be forced by bending into frictionally engaging relation with a lead passing through said collet member.

Claim 8

The suture sleeve assembly of claim 4 in which the bore of said tubular sleeve is proportioned to bias said axially extending legs inwardly when the legs occupy the bore of said tubular sleeve, whereby an elongated lead body may be threaded through said collet member, and said axially extending legs may be forced inwardly by the bore of said tubular sleeve to engage said lead body by assembling the tubular sleeve and collet member after said tubular sleeve has been positioned at a predetermined position on said lead body.
