Abstract
Abstract A suture lumen for securing sutures in surgical procedures which includes a lumen with a head portion at one end of said lumen having a side projection about which suture ends may be wound to secure the ends. A notch or notches in the head portion adjacent the projection are provided to receive the free ends of the suture to prevent release until surgery is completed.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
75 words
A suture lumen for securing sutures in a surgical procedure which comprises: (a) a lumen open at both ends and having a proximal end and a distal end, (b) a projection at one portion of said lumen adjacent the proximal end independent of the lumen passage having an annular recess to receive sutures wound into said recess, and (c) means forming a notch adjacent said projection to frictionally engage suture ends drawn into the notch.
Claim 2
Dependent Claim
75 words
A suture lumen for securing sutures in a surgical procedure which comprises: (a) a lumen open at both ends and having a proximal end and a distal end, (b) a projection at one portion of said lumen adjacent the proximal end independent of the lumen passage having an annular recess to receive sutures wound into said recess, and (c) means forming a notch adjacent said projection to frictionally engage suture ends drawn into the notch.
Claim 3
Dependent Claim
43 words
A suture lumen as defined in claim 1 in which a head portion is formed at the proximal end of said lumen and said projection is mounted on said head portion and comprises a shank portion and a button on said shank portion.
Claim 4
Dependent Claim
34 words
A suture lumen as defined in claim 2 in which a transverse slit is formed in said shank behind said head portion to retain sutures wound around said shank and pulled into said slit.
Claim 5
Dependent Claim
39 words
A suture lumen as defined in claim 2 in which two transverse chordal slits are formed on said shank behind said head portion to retain sutures wound around said shank and pulled into one or more of said slits.
Claim 6
Dependent Claim
37 words
A suture lumen as defined in claim 1 in which a head portion is formed at the proximal end of said lumen having an annular rim provided with one or more notches to frictionally engage suture ends.
Claim 7
Dependent Claim
51 words
A suture lumen as defined in claim 1 in which a head portion is formed at the proximal end of said lumen having an annular rim coaxial with said lumen, said rim having one or more axial slits dimensioned to frictionally engage suture ends when drawn into a slit or slits.
Claim 8
Dependent Claim
67 words
A suture lumen as defined in claim 1 in which a head end is formed at the proximal end of the lumen having an open end surrounded by an annular rim having one or more slits to lock suture ends in frictional engagement, and a button on one side of said head portion adjacent a slit providing an annular recess to receive wound portions of said suture.
