20120078300 | SUTURE ANCHOR AND METHOD FOR FIXATING A SUTURE RELATIVE TO HARD TISSUE - A suture anchor includes a material having thermoplastic properties and is fixated in a hard tissue opening by liquefying at least part of this material and letting it penetrate into walls of the hard tissue opening. During the named fixation and preferably towards the end of it, the suture being held in a distal suture conduit is locked relative to the hard tissue by being clamped between the suture anchor and the wall of the hard tissue opening or by being clamped or braked through collapse of the suture conduit. | 03-29-2012 |
20120095506 | DEVICE AND METHOD FOR FIXATING A SUTURE ANCHOR IN HARD TISSUE - A tool for fixating a suture anchor in 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, includes a distal face, an axial channel and a substantially tube-shaped interface piece fitting into the axial channel of the tool, wherein the axial channel and a proximal end of the interface piece are equipped with catch elements cooperating for catching the interface piece in the axial channel when the interface piece is moved in a proximal direction in the axial channel. | 04-19-2012 |
20120159751 | ANCHORING IN A CONSTRUCTION MODEL - A method suitable for anchoring an anchoring element in an object, which anchoring element is compressible in the direction of a compression axis under local enlargement of a distance between a peripheral anchoring element surface and the compression axis. The anchoring element has a coupling-in face which serves for coupling the mechanical vibrations into the anchoring element, which coupling-in face is not parallel to the compression axis. The anchoring element further includes a thermoplastic material which in areas of the peripheral surface enlargement forms at least a part of the surface of the anchoring element, the method includes the steps of: providing a bore in the object; positioning the anchoring element in the bore; and coupling the compressing force and the mechanical vibrations through the coupling-in face into the positioned anchoring element. | 06-28-2012 |
20120197296 | METHOD AND DEVICE FOR FIXATING A SUTURE ANCHOR WITH A SUTURE IN HARD TISSUE - A suture anchor retaining a suture is fixated in hard tissue, in particular in bone tissue, using any per se known method and is then secured using a securing element including a material having thermoplastic properties, which is liquefied in situ and made to penetrate the hard tissue in which the suture anchor is fixated. The securing element is e.g. a thermoplastic plug or thermoplastic sleeve which is anchored above the suture anchor in a mouth area of the same hard tissue opening. Alternatively the securing element is a thermoplastic pin which is introduced into an inner cavity of the suture anchor, wherein the material having thermoplastic properties is liquefied in this cavity and, in a liquid state is pressed through passages connecting the cavity with outer surfaces of the anchor. | 08-02-2012 |
