Comprehensive tissue attachment system
First Claim
1. A bone anchor operative to selectively control the tension of a suture held thereby comprising:
- a. an anchor portion operative to be seated within a bone mass;
b. an attachment portion coupled to said anchor portion, said attachment portion defining an attachment point to which said suture is affixed to said bone anchor; and
c. an adjustment mechanism operatively coupled to said attachment portion, said adjustment mechanism being operative to selectively adjust said attachment portion such that the tension of said suture affixed thereto is correspondingly altered.

Abstract
Bone anchors, methods for deploying anchors, and systems for attaching ligaments and tendons to bone are disclosed. The bone anchors of the present invention are operative to remain firmly positioned within a target site of bone and provide means for selectively adjusting the degree of tension to one or more sutures secured thereto. The bone anchors are further operative to be utilized to connect tendons and ligaments directly to bone, as well as may be selectively utilized to adjustably position an implant or other anatomical structure held thereby. There is further disclosed methods for deploying a bone anchor utilizing a blind procedure that is expeditious, accurate and substantially less traumatic than prior art bone deployment techniques.

13. A bone anchor operative to selectively control the tension of a suture held thereby comprising:
-
a. an anchor portion operative to be seated across a bone mass, said anchor portion defining a channel extending through said bone mass;
b. an attachment portion defining an attachment point to which said suture is affixed to said bone anchor; and
c. an adjustment mechanism operatively coupled to said anchor portion and said attachment portion, said adjustment mechanism being operative to selectively adjust said attachment portion such that the tension of said suture affixed thereto is correspondingly altered. - View Dependent Claims (14, 15, 16)

17. A system for selectively attaching a tendon or ligament to a bone comprising:
-
a. an anchor portion operative to be seated across a bone mass, said anchor portion defining a channel extending through said bone mass;
b. an attachment portion defining an attachment point to which said suture is affixed to said bone anchor; and
c. an adjustment mechanism operatively coupled to said anchor portion and said attachment portion, said adjustment mechanism being operative to selectively adjust said attachment portion such that the tension of said suture affixed thereto is correspondingly altered;
d. a saddle member operatively positionable upon a respective open end of said channel formed through said bone mass, said saddle member being operative to receive and hold a free end of a tendon or a ligament thereupon, said saddle member having a bore formed therethrough in fluid communication with said channel formed through said bone mass, said bore forming a passageway through which a suture coupled to said tendon may extend to said bone anchor.

18. A method of securing a bone anchor to bone comprising the steps:
-
a. forming a channel extending from said target site of bone and through a section of soft tissue such that said channel extends externally from the body of said patient;
b. identifying a site through said channel formed in step (a) to where said bone anchor will be positioned;
c. forming a bore within said bone at said site identified in step (b); and
d. depositing said bone anchor within said bore formed in step (c). - View Dependent Claims (19, 20, 21, 22)
