Abstract
A device for fixating a suture anchor beyond a hard tissue opening with the aid of a material having thermoplastic properties and energy transmitted to the suture anchor for in situ liquefaction of at least part of the material having thermoplastic properties. The device includes a tool and a suture anchor. The tool has a proximal end suitable for being coupled to an energy source and a distal end suitable for arrangement of the suture anchor including the suture. The distal end includes a distal tool face and an axial channel with a distal mouth located in the distal tool face. The suture anchor has an anchor foot and a thermoplastic sleeve including the material having thermoplastic properties. The anchor foot holds a loop of a suture such that end sections of the suture reach through the thermoplastic sleeve and a portion of the distal tool face.
