First Claim
Patent Images
1. A bone anchor for anchoring tissue to bone, comprising:
- an elongate body defined by a longitudinal axis, a first leading end and a second trailing end, the elongate body having an asymmetrical profile with respect to the longitudinal axis; and
at least one suture channel formed in the elongate body and having opposed first and second openings, the first and second openings being laterally offset from each other, and the first opening being positioned closer to the first leading end than the second opening such that the at least one suture channel is obliquely angled with respect to the longitudinal axis such that applying tension to a suture strand extending through the channel is effective to toggle the bone anchor in two planes.

Abstract
A bone anchor is provided that can toggle in two planes for secure anchorage within a bone cavity. The bone anchor includes an oblique suture channel configured such that a suture strand extending through the bone anchor can be tensioned to toggle the bone anchor inside the bone cavity. The suture strand can be located on the same side of the anchor body to maximize the area of the anchor surface which engages bone, resulting in increased engagement into bone and resistance to tensile forces.
