摘要

Various bone anchor assemblies and methods are provided for anchoring tissue to bone. In one embodiment, an anchor assembly for anchoring a tendon to bone is provided and includes a substantially cylindrical sheath having bone-engaging surface features formed on an external surface thereof, and having an inner lumen formed therein and extending from an open proximal end to a substantially closed distal. The substantially closed distal end includes at least one tendon anchoring feature extending distally therefrom and configured to facilitate anchoring of a tendon to bone. The anchor assembly further includes an expander having a generally elongate cylindrical configuration and being sized and shaped to be received within the inner lumen of the sheath.
