Abstract

A wedge for an anchor system is disclosed. One embodiment of the wedge includes at least two circumferential wedge segments. Each segment defines an exterior tapered surface and an interior surface. The interior surface has gripping elements thereon. The gripping elements define a difference between a major diameter and a minor diameter of about 0.25 to 0.75 of an amount of a difference defined by a conventional thread having substantially a same axial spacing and major diameter as the gripping elements on the interior surface. Another embodiment of the wedge has an interior surface shaped to substantially conform to an exterior surface of a tendon.
