sleeve both as described above or it may comprise a body of biocompatable metal or plastic material having the bendable pointed legs embedded therein or otherwise secured at the distal end of the body and with a loop or other anchor engagement structure at the proximal end of the body the configuration of the anchor body is not of itself critical to the invention although certain configurations such as those described herein are more advantageous than others the key features again are the fact that the legs are deformable to effect deployment while the anchor is in the bone tunnel to permit the anchor to be removed after insertion but prior to bending for deployment a passage for engaging a suture looped about or through the anchor and a mechanism for engaging the anchor with a removable insertion tool capable of selectively deploying the anchor in the tunnel by causing the legs to deformably bend outwardly without hammering or impacting the anchor the specific insertion tool configurations described herein although particularly advantageous can also be varied within the scope of the invention the key features of the tool are the capability of engaging the anchor for selective insertion into and removal from the bone tunnel and.
