Abstract:
1. A method for holding soft tissue in apposition with a bone using a suture, comprising engaging the soft tissue with an engaging portion of a suture thread; engaging an end of the suture thread with a rotatable shaft of an anchor; implanting the rotatable shaft in the bone; and rotating the shaft in a first direction to wrap the engaged suture thread onto the shaft thereby increasing tension on the suture and on the soft tissue; the anchor further comprising an outer tubular member, substantially surrounding the rotatable shaft, wherein the step of rotating the shaft to wrap the engaged suture thread onto the shaft includes, as the suture thread is wrapped onto the shaft, contacting an inner surface of the outer tubular member with the wrapped suture thread to exert an outward force on a retaining portion of the outer tubular member to outwardly deform the retaining portion, wherein the outwardly deforming retaining portion contacts the bone.
