Knotless suture anchoring device having deforming section to accommodate sutures of various diameters
First Claim
1. A knotless suture anchor apparatus for anchoring a length of suture with respect thereto, comprising:
- an anchor body having a proximal end, a distal end, and a lumen opening at the proximal end, the anchor body further including a suture return path such that a length of suture may be introduced into a lumen from the proximal end, and passed out of the lumen through the proximal end; and
a suture locking plug movable within the lumen from a first position which does not interfere with axial movement of the length of suture to a second position that compresses the length of suture against the anchor body and interferes with axial movement of the length of suture, wherein the lumen is sized to be larger than the locking plug and wherein at least one of said plug or the anchor body comprises a selectively deformable section, and wherein the deformable section is sized to deform only by the presence of both the length of suture and the suture locking plug within the lumen to accommodate and secure said suture as it is compressed.

Abstract
An innovative bone anchor and methods for securing soft tissue, such as tendons, to bone, which permit a suture attachment that lies entirely beneath the cortical bone surface. The suturing material between the soft tissue and the bone anchor may be secured without the need for tying a knot. The suture attachment to the bone anchor involves the looping of a length of suture around a suture return member or path within the bone anchor, tightening the suture and attached soft tissue, and compressing the suture against the bone anchor. The bone anchor may be a tubular body having a lumen with a locking plug that compresses the suture therein. One of the components of the locking structure may include a deformable or flexible section, member, or surface. The locking plug may include a shaft and an enlarged head that interferes with the tubular body to provide a positive stop. An actuation rod attached at a frangible section to the shaft may be manipulated by an external handle during locking of the suture within the bone anchor. The bone anchor further may include locking structure for securing itself within a bone cavity.

16. A knotless suture anchor apparatus for anchoring a length of suture with respect to a body cavity, comprising:
-
an anchor body having an anchoring structure for fixing the anchor body within a body cavity, the anchor body having a proximal end, a distal end, a lumen and a lumen opening at both the proximal and distal ends, the lumen having a diameter that permits a length of suture to be passed therethrough; and a suture locking plug comprising a shaft axially displaceable within the lumen, wherein the suture locking plug is movable within the lumen from a first position which does not interfere with axial movement of the length of suture to a second position that interferes with axial movement of the length of suture, wherein the plug is sized to be smaller than the lumen and wherein said plug and said body are adapted to have a difference in rigidity such that at least one of the plug or the body shall selectively deform, and wherein the at least one of the plug or the body is sized to deform only by the presence of both the length of suture and the suture locking plug within the lumen to accommodate and secure the suture. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)

27. A suture-locking apparatus for anchoring a suture within a body cavity, comprising:
-
a body member having a proximal end, a distal end, and an axial lumen in between said proximal and distal ends, said proximal end adapted for passing a portion of a suture into said lumen; and a plug member movable from a first position to a second position in said lumen, wherein said lumen is sized to be larger than said plug member, said plug member comprising a radial protrusion adapted for compressing said suture against said body member on moving to said second position; and wherein at least one of said plug member or the body member comprises a selectively deformable section, and wherein the deformable section is sized to deform only by the presence of both the suture and the plug member within the lumen to accommodate and secure said suture as it is compressed. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)

45. A knotless suture-locking apparatus for anchoring a suture within a body cavity, comprising:
-
a body member for fixing said suture-locking apparatus within a body cavity, said body member having a proximal end, a distal end, and a lumen, the lumen comprising an opening at said proximal end to receive a length of suture therein; and a suture-locking plug member comprising a radial protrusion for positively interfering with proximal movement of said suture-locking plug with respect to said body member, wherein said suture-locking plug member is movable within said lumen from a first position that does not interfere with axial movement of said length of suture, to a second position that interferes with axial movement of said length of suture; and wherein at least one of the suture-locking plug or the body member comprises a selectively deformable section, and wherein the deformable section is sized to deform only by the presence of both the suture and the suture-locking plug within the lumen to accommodate and secure the suture as it is compressed. - View Dependent Claims (46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61)
