at least one tissue securing suture having a suture length and supported by the rigid support, wherein the at least one tissue securing suture includes a first end and a second end that extend out of the opening located at the proximal end of the anchor body, and the rigid support is spaced axially away from the opening at the proximal end along the central longitudinal axis; and
a driver including a shaft having a shaft length, the shaft engaging the anchor body, and the suture length of the at least one tissue securing suture is greater than the shaft length of the shaft.

Abstract
A suture anchor assembly includes an anchor having a proximal end, a distal end, a longitudinal axis, a first length, and an internal passage within the anchor. The internal passage begins at an opening in the proximal end and has a second length shorter than the first length. A support structure fixed longitudinally relative to the anchor extends across the internal passage and has a third length shorter than the second length. A suture within the internal passage is received about a distal surface of the support structure. A suture extends out of the opening in the proximal end. A driver includes a cannula having a distal opening and a proximal opening, and the suture is received within the cannula. A first end and the second end of the suture extend outside of the proximal opening, the driver having a drive surface near the distal opening that engages the anchor.
