Soft tissue anchor
View Patent ↗A soft tissue anchor is provided for attaching soft tissue to bone. The anchor is useful generally throughout the body where soft tissue needs to be anchored to bone. It is particularly useful for reattaching separated tissues adjacent to an articular joint such as the hip, knee, or shoulder. For example it is well suited for reattaching labral tissue that has become separated from the glenoid rim adjacent a shoulder joint.
1. A soft tissue anchor for attaching soft tissue to a bone, the soft tissue anchor comprising:
an elongated shaft having an axis, a proximal end, and a distal end;
a bone engaging means affixed to the shaft for securing the distal end of the shaft in the bone; and
a transverse head engageable with the soft tissue to be attached to the bone, the transverse head extending in a first direction to a first point situated a first predetermined distance outwardly from the axis and extending in a second direction, generally opposed to the first direction, to a second point situated a second predetermined distance outwardly from the axis, the second predetermined distance being less than the first predetermined distance, the transverse head having a width equal to or greater than that of the proximal end of the shaft and the transverse head having a transverse bottom surface adjacent the shaft, a first projection extending a third predetermined distance distally from the first point, a second projection extending a fourth predetermined distance distally from the second point wherein the transverse head further comprises a circular member having a centerline offset a perdetermined distance laterally from the axis of the shaft, the circular member including a first flattened rim adjacent the second point.
2. A soft tissue anchor according to claim 1 further comprising a pair of diametrically opposed flattened rim portions orthogonally situated relative to the first flattened rim.
