  • Patent number: 8776479
    Abstract: An anchoring device including an anchoring element suitable for being anchored an object of construction material with the aid of mechanical vibrations. The anchoring element includes a thermoplastic material and a tool. The thermoplastic material forms at least a part of a radially outer surface of the anchoring element, and the tool has a proximal portion and a broadening portion distally of the proximal portion. The broadening portion has an outer second cross-section, the second cross section being larger than the first cross section but being adapted to the first cross section so that the tool can be moved with respect to the anchoring element while the broadening portion is in the axially-extending opening and locally expands the anchoring element while thermoplastic material of the anchoring element that surrounds the broadening portion is in a solid state.

  • Patent number: 8756790
    Abstract: A first and a second object are joined with the aid of a joining element including at least in the region of its distal and proximal ends a thermoplastic material. Two blind holes facing each other are provided in the two objects and the joining element is positioned in the blind holes such that its distal and proximal ends are in contact with the bottom faces of the blind holes and such that there is a gap between the two objects. This assembly is then positioned between a support and a sonotrode. The sonotrode and the support are forced towards each other, while the sonotrode is vibrated, thereby liquefying at least part of the material having thermoplastic properties, there, where the joining element ends are pressed against the bottom faces of the holes and allowing the liquefied material to infiltrate into pores.

    Abstract: A device for the anchoring of a suture in tissue includes a guide sleeve, a sonotrode, an anchor and the suture. The guide sleeve has a distal part with a smaller cross section and a proximal part with a larger cross section. The sonotrode extends through the lumen of the guide sleeve and has a distal end and a proximal end, the proximal end being designed for coupling the sonotrode to a vibration source (e.g. an ultrasonic device). The anchor is arranged at the distal end of the device and includes an anchor foot and an anchoring sleeve sitting on a shoulder of the anchor foot. The anchoring sleeve consists of a material which is liquefiable through mechanical vibrations. A middle portion of the suture runs through the anchor foot and two end portions of the suture are attached to the guide sleeve.

  • Publication number: 20140057067
    Abstract: A lightweight component is equipped with two cover layers, which are made of a wood material, and a filling disposed in between the layers after cutting everything to size, having an edge support including thermoplastic material. The edge support is anchored in both the first and second cover layers starting from the narrow side. Anchoring is achieved by bringing the edge support into contact with the respective cover layer and coupling mechanical vibrations into the edge support by a sonotrode engaging from the narrow side. The edge support at the same time is pressed against the cover layer such that, in the region of a transition between the thermoplastic material and the wood material of the cover layer, part of the thermoplastic material is liquefied and pushed into the cover layer material, thereby producing a positively engaged anchoring after hardening.

  • Publication number: 20140039474
    Abstract: A light diffuser, which is particularly suitable for introducing diffuse light into a tissue, is produced by interpenetration of a diffuser material in a liquid state into a boundary layer of a porous shaping material, by which process a diffuser surface is formed having a surface structure which represents essentially a negative of the pore structure of the shaping material and includes undercut structures induced by a surface tension. The light diffuser is e.g. produced by introducing a diffuser blank including material that is liquefiable through mechanical vibration into the shaping material and simultaneously stimulating it with mechanical vibrations, such that the liquefiable material liquefies at least there where it is in contact with the shaping material and is pressed into the shaping material. An in situ production of the diffuser is particularly advantageous for photodynamic therapy in bone tissue.
