Abstract

Abstract An anchor for attaching soft tissue to a bone comprising a head having a central dome with a suture bore extending therethrough. The dome includes a pair of substantially flat, oppositely disposed lands configured for engagement to a driving tool for inserting the anchor into the bone. A shaft extend from the head, and includes a first series of helical threads having a first diameter, and second series of helical threads interleaved with the first series of threads. The second series of threads has a diameter substantially different than the first diameter. The anchor employs a guide wire bore extending along the length of the anchor shaft.
