Abstract
A knotless suture anchor and method for its insertion into tissue are provided. The suture anchor includes an inner member including a proximal shaft and a distal securing member shaped to secure the inner member to the tissue, the proximal shaft including a first locking part and at least one hole extending therethrough for receiving the suture thread; and a collar member including an axial bore shaped to receive the proximal shaft of the inner member, a second locking part, and at least one hole extending therethrough and assigned to the hole of the proximal shaft of the inner member, the collar member being axially slidable into unlocked and locked positions relative to the proximal shaft of the inner member, the collar member being relatively axially slidable into the locked position only to secure the suture thread. The hole of the collar member is aligned with the hole of the proximal shaft of the inner member when the collar member is placed into the unlocked position, the hole of the collar member is misaligned with the hole of the proximal shaft of the inner member when the collar member is placed into the locked position, and the first locking part of the proximal shaft e…
