Suture passer and subcortical knot placment

A suture passer and method of using for the exchange of sutures between sections of a device used for attachment of tissue to bone or delivering suture to a separate device with the purpose of pushing then pulling suture through a plane of bone and/or tissue. In one embodiment a U-shaped or teardrop-shaped ridged material (solid wire, braided wire, monofilament extruded polymer) stiffer than the intended suture material is used to pass the suture. Suture material or passing loops may be further contained in a preloaded tube or slotted tube that provides additional stiffening and the elimination of surgical steps. In another embodiment, a method of subcortical-transosseous knot placement is described which increases the load bearing and eliminates post surgical impingement with the acromion.
