Suture screw
First Claim
1. A suture screw comprising:
- a sleeve having a threaded outer surface and a longitudinal bore; and
a pin having a tip and a shaft extending proximally from the tip, the shaft having at least one transverse bore extending from a first side of the shaft to a second side of the shaft, wherein the shaft is positioned within the longitudinal bore of the sleeve.

Abstract
A two part suture screw for anchoring tissue and bone is disclosed. The suture screw includes a threaded outer sleeve having a longitudinal bore extending therethrough. A pin having a conical insertion tip is provided and includes a proximally extending shaft configured for insertion in the longitudinal bore of the outer sleeve. The shaft includes a transverse bore through the pin for slidingly receiving a length of suture. A pair of channels extend from the transverse bore proximally along the outer surfaces of the shaft. The sleeve is provided with corresponding channels which extend proximally from a point adjacent the throughbore to form a complete bore for free sliding receipt of the suture within the suture screw. The suture contemplated for use with the disclosed suture screw has a diameter smaller than that of the transverse bore and the bores formed by the channels of the pin and sleeve to allow the suture to freely slide therein. A method of using the suture anchor to anchor tissue to bone is also disclosed.

10. A suture screw for receipt of a length of suture to secure tissue to bone comprising:
-
an outer sleeve having a longitudinal bore there through, the longitudinal bore having a predetermined cross-sectional shape; and
a pin having a distal tip and a shaft extending proximally from the tip and has a cross-sectional shape similar to the cross-sectional shape of the throughbore such that when the shaft is inserted into the throughbore, there is a minimal rotation between the pin and the sleeve. - View Dependent Claims (11, 12, 13, 14, 15, 17)

16. A method of anchoring tissue to bone comprising:
-
providing a two part suture screw having a threaded outer sleeve and a longitudinal bore and a pin, having a distal insertion tip and a proximal shaft having a transverse bore, attached to the sleeve such that the shaft is positionable within the longitudinal bore and at least one length of suture extending through the transverse bore and freely slidable therein;
threading the suture screw into bore;
attaching one end of the suture to tissue;
tensioning the suture to draw the tissue adjacent the bone; and
tying the suture to secure the tissue to bone.
