Surgical anchor

摘要

The anchor includes a body (14) and a plurality of barbs (44) located in axially aligned, circumferentially spaced relation to each other about the body. The barbs have a normal configuration wherein they extend rearwardly and radially outwardly from the anchor body to outer ends which are normally located outside a longitudinal projection of the largest geometric cross-section of the body transverse to its longitudinal axis. The barbs may be elastically deformed to a configuration wherein they are located substantially within the longitudinal projection. A transverse bore (26) extends through the front portion of the anchor for engagement by a length of cord-like material. Also, an opening (30) oriented perpendicularly to the bore extends through a flattened rear portion of the anchor. Further, a longitudinal slot (31) aligned with the opening connects the front end of the anchor body to the opening. This slot minimizes the force necessary to pull the anchor into its desired position relative to the bone and allows the anchor to be disconnected from the object and removed after deployment.
