DEVICE AND METHOD FOR FIXATING A SUTURE ANCHOR WITH A SUTURE OR A HEADED ANCHOR IN HARD TISSUE

摘要

Device and method are suitable for fixating soft tissue to hard tissue withthe aid of asuture anchor and a suture or with the aid of a headed anchor, the anchorbeingforced into the hard tissue and then anchored therein by in situ liquefactionof amaterial having thermoplastic properties. The device comprises a vibrationtool andthe anchor and possibly a support element, wherein the anchor comprises ananchorfoot and a thermoplastic sleeve. The thermoplastic sleeve comprises thematerialhaving thermoplastic properties. The anchor foot has a distal end suitable forbeingforced into hard tissue and it is connected to the distal end of the vibrationtool andthe thermoplastic sleeve sits on a proximal face of the anchor foot, thevibration tooland/or a proximal portion of the anchor foot extending into or through thethermoplastic sleeve.
