Bone anchor device having toggle member for attaching connective tissues to bone
First Claim
1. A bone anchor device for attaching connective tissue to bone, said bone anchor device being associated with a suturing material to secure said connective tissue thereto, said device having a proximal end, and a distal end, and a longitudinal axis extending from said proximal end to said distal end, and comprising:
- a toggle member, the toggle member having an aperture;
a tubular body member disposed distally of the toggle member, such that there is an axial space extending along said longitudinal axis between said toggle member and said body member, the body member having a lumen extending along said longitudinal axis and a lumen opening at the proximal end, the body member further having a suture return member disposed therein such that a length of suture may be introduced into the lumen from the proximal end through the aperture, looped around the suture return member, and passed out of the lumen through the proximal end and the aperture; 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 wherein the aperture is oriented coaxially to the longitudinal axis, said toggle member adapted to be deployed independent or separate from said suturing material; 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.
