Patent number: 8114137Abstract: Implants (7) for forming a positive connection with human or animal parts include a material, such as thermoplastics and thixotropic materials, that can be liquefied by means of mechanical energy. The implants (7) are brought into contact with the tissue part, are subjected to the action of ultrasonic energy while being pressed against the tissue part. The liquefiable material liquefies and is pressed into openings or surface asperities of the tissue part so that, once solidified, the implant is positively joined thereto. The implantation involves the use of an implantation device that includes a generator (2), an oscillating element, and a resonator (6). The generator (2) causes the oscillating element to mechanically oscillate, and the element transmits the oscillations to the resonator (6). The resonator (6) is used to press the implant (7) against the tissue part to transmit oscillations to the implant (7).Type: GrantFiled: June 8, 2007Date of Patent: February 14, 2012Assignee: Woodwelding AGInventors: Marcel Aeschlimann, Laurent Torriani, Antonino Lanci, Jorg Mayer

Publication number: 20090318912Abstract: A light diffuser (10), 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 (4) 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 (10) is e.g. produced by introducing a diffuser blank (1) including material which 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 (20).Type: ApplicationFiled: June 18, 2009Publication date: December 24, 2009Applicant: WOODWELDING AGInventors: Jörg Mayer, Marcel Aeschlimann, Laurent Torriani, Heinrich Walt

Publication number: 20090131947Abstract: An anchorage in tissue is produced by holding a vibrating element and a counter element against each other such that their contact faces are in contact with each other, wherein at least one of the contact faces comprises a thermoplastic material which is liquefiable by mechanical vibration. While holding and then moving the two elements against each other, the vibrating element is vibrated and due to the vibration the thermoplastic material is liquefied between the contract faces, and due to the relative movement is made to flow from between the contact faces and to penetrate tissue located adjacent to outer edges of the contact faces. For liquefaction of the thermoplastic material and for displacing it from between the contact faces no force needs to act on the tissue surface which is to be penetrated by the liquefied material. For this reason anchorage in tissue which has little mechanical stability is possible.Type: ApplicationFiled: October 29, 2008Publication date: May 21, 2009Applicant: WOODWELDING AGInventors: Marcel Aeschlimann, Laurent Torriani, Mario Lehmann, Jorg Mayer, Richard Lum, Kyle Craig Pilgeram, Michael Baycura, Lisa Ballou
