ABSTRACT:
A wedge for a tendon retaining anchor includes at least two circumferential wedge segments adapted to be placed on an exterior of a tendon. The wedge segments have an exterior surface adapted to cooperate with a receiving bore of a load transfer device and an interior surface having gripping elements thereon. A circumferential dimension of the wedge segments is selected so that a total uncompressed gap between circumferential ends of the wedge segments when the segments are applied to an exterior surface of the tendon is at most about 2.4 times a height of the gripping elements. In another aspect, a tendon retaining system includes an anchor having a wedge receiving bore and wedge segments adapted to cooperate with the wedge receiving bore. The wedge segments include gripping elements on an interior surface thereof. The system includes a device adapted to limit lateral compression of the wedge segments.
