Abstract
Abstract A surgical method and tools for anchoring a suture to bone is disclosed. The method includes forming an opening through a top surface of the bone, positioning a suture within the opening and crimping a region of the top surface of the bone surrounding the opening to anchor the suture within the opening. The tools used with the disclosed surgical method include a punch, a broach, a guide and a swage. The punch and the broach are used to create a uniform diameter opening in the bone by compressing bone material. The guide is used to position a suture, preferably having a shoulder, in the opening. Finally, the suture is used to crimp the region of the top surface of the bone surrounding the opening.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
81 words
A surgical method for anchoring a suture, having a first end and second end, to a bone having a top surface, the method including: forming an opening in the bone through the top surface; positioning the first end of the suture within the opening such that the second end of the suture extends from the opening; and crimping a region of the top surface of the bone surrounding the opening to secure the first end of the suture within the opening.
Claim 2
Dependent Claim
81 words
A surgical method for anchoring a suture, having a first end and second end, to a bone having a top surface, the method including: forming an opening in the bone through the top surface; positioning the first end of the suture within the opening such that the second end of the suture extends from the opening; and crimping a region of the top surface of the bone surrounding the opening to secure the first end of the suture within the opening.
Claim 3
Dependent Claim
47 words
The surgical method of claim 1 wherein the suture has a first diameter, the method further including: forming a shoulder on the first end of the suture, wherein the shoulder has a second diameter which is greater than the first diameter and is positioned within the opening.
Claim 4
Dependent Claim
21 words
The surgical method of claim 2 wherein forming a shoulder includes creating a knot on the first end of the suture.
Claim 5
Dependent Claim
18 words
The surgical method of claim 2 wherein forming a shoulder includes melting the first end of the suture.
Claim 6
Dependent Claim
21 words
The surgical method of claim 2 wherein forming a shoulder includes attaching a peg to the first end of the suture.
Claim 7
Dependent Claim
43 words
The surgical method of claim 2 wherein the opening is defined by an upper portion and a lower portion, and further wherein positioning the first end of the suture within the opening includes positioning the shoulder below the upper portion of the opening.
Claim 8
Dependent Claim
31 words
The surgical method of claim 6 wherein crimping the region surrounding the opening includes crimping the upper portion of the opening to a diameter which is less than the second diameter.
Claim 9
Dependent Claim
24 words
The surgical method of 2 wherein positioning the first end of the suture within the opening includes positioning the shoulder below the top surface.
Claim 10
Dependent Claim
24 words
The surgical method of 2 wherein positioning the first end of the suture within the opening includes positioning the shoulder below the top surface.
Claim 11
Dependent Claim
16 words
The surgical method of claim 1 wherein the top surface of the bone is cortical tissue.
Claim 12
Dependent Claim
14 words
The surgical method of claim 1 wherein forming an opening includes compressing bone tissue.
Claim 13
Dependent Claim
28 words
The surgical method of claim 1 wherein forming an opening includes: creating a notch in the top surface of the bone; and expanding the notch to uniform diameter.
Claim 14
Dependent Claim
