Method and apparatus for attaching connective tissues to bone using a knotless suture anchoring device
First Claim
1. A bone anchor device for attaching connective tissue to bone, said device having a longitudinal axis and comprising:
- a toggle member comprising a ring;
a body member disposed distally of the toggle member, such that there is an axial space between said toggle member and said body member; and
a connecting portion disposed in said axial space and joining said toggle member to said body member;
said toggle member being movable between an undeployed position wherein said toggle member has a smaller profile in a direction transverse to said axis and a deployed position wherein said toggle member has a larger profile in said direction transverse to said axis; and
said connecting portion deforming when said toggle member is moved from said undeployed position to said deployed position such that said axial space is reduced in length.

Abstract
A device for attaching connective tissue to bone has a longitudinal axis and comprises an annular toggle member and a body member disposed distally of the toggle member, such that there is an axial space between the toggle member and the body member. The toggle member is movable between an undeployed position wherein the toggle member has a smaller profile in a direction transverse to the axis and a deployed position wherein the toggle member has a larger profile in the direction transverse to the axis. When installed in a desired procedural site, in suitable bone, suturing material extends axially through a center aperture in the annular toggle member, without being secured to or contacting the toggle member. This approach permits a suture attachment which lies entirely beneath the cortical bone surface, and which further permit the attachment of suture to the bone anchor without the necessity for tying knots, which is particularly arduous and technically demanding in the case of arthroscopic procedures.

31. Apparatus for attaching connective tissue to bone, comprising:
-
an anchor body having a longitudinal axis and having an anchoring structure for fixing the anchor body within a body cavity, the 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 member disposed therein such that a length of suture may be introduced into the lumen from the proximal end, looped around the suture return member, and passed out of the lumen through the proximal end;
a suture locking plug movable within the lumen from a first position to a second position; and
a bone anchoring member attached to said anchor body and movable between an undeployed position and a deployed position. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)
