Abstract

A surgical assembly includes a first guidewire and a second guidewire, in which each of the first guidewire and the second guidewire are configured to be received by a bone block, a first suture loop, a second suture loop, a first locking component, and a second locking component, in which the first locking component is coupled to the first suture loop and the second locking component is coupled to the second suture loop. The locking component has a hole formed therethrough, in which the hole of the locking component is configured to receive the suture, and may be tethered to a suture by knots engaging a counterbore at opposed ends of a bore defined by the hole.

First claim

What is claimed is:

1. A surgical delivery apparatus comprising:
a suture; and
a locking component having a hole formed therethrough,
wherein the hole of the locking component is configured to receive the suture,
wherein the suture is disposed through the hole formed through the locking component and formed into a closed loop which extends a distance away from and loops back to the locking component, and
wherein an end of the closed loop distal from the locking component is threaded through a receiving guidewire loop and then back through itself to join the surgical delivery device with the receiving guidewire loop, whereby the locking component is positioned at an intersection point between the receiving guidewire loop and the closed loop of the surgical delivery apparatus.

2. The apparatus of claim 1 , wherein a first knot and a second knot are formed on the suture to form the suture into the closed loop.

3. The apparatus of claim 2 , wherein movement of the locking component along the suture is restricted by both the first knot and the second knot formed on the suture.

4. The apparatus of claim 3 , wherein at least a portion of each of the first knot and the second knot formed on the suture are seated within the hole formed through the locking component.

5. The apparatus of claim 1 , wherein the locking component is substantially spherical in shape and comprises a biocompatible material.

6. The apparatus of claim 1 , wherein the closed loop is formed by threading a first end of the suture through the hole in the locking component in a first direction and a second end of the suture through the hole in the locking component in a second opposite direction and knotting the first and second threaded ends to the closed loop on respective sides of the locking component.

7. The apparatus of claim 6 , wherein the forming of the closed loop further includes trimming the ends of the suture after the knotting thereof.

8. The apparatus of claim 6 , wherein the forming of the closed loop further includes pulling the loop taut such that the knots are seated or disposed, within the hole.

9. The apparatus of claim 8 , wherein movement of the locking component along the suture is restricted by the knots.

10. The apparatus of claim 1 , wherein the closed loop extends away from a first end of the hole in the locking component and loops back around to a second opposite end of the hole in the locking component.

11. A method of forming a closed loop for a surgical delivery apparatus, the method comprising:
providing a suture and a locking component, the locking component having a hole formed therethrough and is configured to receive the suture;
disposing a first end of the suture through the hole formed through the locking component in a first direction;
disposing a second end of the suture through the hole formed through the locking component in a second direction that is opposite to the first direction;
forming a first knot on the suture with the first end of the suture; and
forming a second knot on the suture with the second end of the suture.

12. The method of claim 11 , further comprising:
tightening the suture such that at least a portion of both the first knot and the second knot are seated within the hole formed through the locking computer.

13. The method of claim 11 , further comprising:
trimming the first end of the suture on a region of the suture near the first knot; and
trimming the second end of the suture on a region of the suture near the second knot.

14. The method of claim 13 , wherein a trimming tool is used to trim each of the first end and the second end of the suture such that fraying of the suture does not occur as a result of the trimming.

15. The method of claim 11 , wherein the locking component is substantially spherical in shape and comprises a biocompatible material.
