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. |

1. A suture anchor assembly, comprising:
an anchor body including a distal end, a proximal end, an exterior surface, a length extending along a central longitudinal axis of the anchor body, a passage, and a helical thread extending at least partially around the passage, wherein the passage extends about the central longitudinal axis, the passage extends at least partially along the length of the anchor body, and the passage extends from an opening located at the proximal end of the anchor body; a rigid support fixed by the anchor body against relative movement along the central longitudinal axis of the anchor body, wherein the passage is defined by a first interior surface spaced opposite to a second interior surface, and the rigid support is attached to the first interior surface and to the second interior surface, wherein the rigid support has a first dimension that is generally parallel to the central longitudinal axis of the anchor body and a second dimension that is generally perpendicular to the central longitudinal axis of the anchor body, the second dimension is longer than the first dimension, the rigid support extends across the passage and to the exterior surface, the exterior surface having a first exterior surface and a second exterior surface, the first exterior surface spaced from the second exterior surface, wherein the second dimension is defined between the first exterior surface and the second exterior surface; 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. |
