Abstract
A suture anchor assembly includes an anchor body having a central longitudinal axis, a proximal end, a distal end, a passage extending along the central longitudinal axis from an opening at the proximal end through a portion of a length of the anchor body, and a helical thread that defines a perimeter the proximal end of the anchor body. The passage has a first wall portion and a second wall portion. A rigid support extends across the passage and has a first portion and a second portion spaced from the first portion. The first portion is attached to the first wall portion and the second portion is attached to the second wall portion. A suture strand having a suture length is threaded into the passage, supported by the rigid support, and threaded past the proximal end of the anchor body. The rigid support is spaced axially away from the opening, and the suture strand extends out of the opening of the anchor body. A driver includes a shaft having a shaft length that engages the anchor body, and the suture length of the at least one suture strand is greater than the shaft length of the shaft.
