Suture screw
First Claim
1. A suture screw comprising:
- a sleeve having a threaded outer surface and a longitudinal bore, the threads of the sleeve being interrupted at the distal end of sleeve; and
a pin having a tip and a shaft extending proximally from the tip, the tip of the pin having interrupted threads formed in an outer surface thereof, 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.

2. A suture screw for receipt of a length of suture to secure tissue to bone comprising:
-
a non-expandable outer sleeve having a longitudinal bore there through, the longitudinal bore having a predetermined cross-sectional shape; and
a pin having a distal tip, the distal tip of the pin having interrupted threads formed in an outer surface thereof, and a shaft extending proximally from the tin and has a cross-sectional shave 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, wherein the pin includes a transverse bore formed through the shaft for receipt of a length of suture. - View Dependent Claims (3)

4. A suture screw for receipt of a length of suture to secure tissue to bone comprising:
-
a non-expandable outer sleeve having a longitudinal bore there through, the longitudinal bore having a predetermined cross-sectional shape; and
a pin having a distal tip, the distal tip of the pin having interrupted threads formed in an outer surface thereof, 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, wherein a portion of the outer surface of the tip is smooth and conical.
