Patent number: 8623050Abstract: 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.Type: GrantFiled: March 2, 2009Date of Patent: January 7, 2014Assignee: Woodwelding AGInventors: Mario Lehmann, Laurent Torriani, Stephanie Mehl, Jörg Mayer

Patent number: 8597446Abstract: The lightweight component is equipped with two cover layers, which are made of a wood material, for example, and a filling disposed in between said layers after cutting everything to size, having an edge support comprising thermoplastic material. This is done in that the edge support is anchored both in the first cover layer and in the second cover layer starting from the narrow side, wherein the anchoring is achieved in that the edge support is brought into contact with the respective cover layer and mechanical vibrations are coupled into the edge support by a sonotrode engaging from the narrow side, wherein 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.Type: GrantFiled: October 27, 2009Date of Patent: December 3, 2013Assignee: Woodwelding AGInventors: Laurent Torriani, Mario Lehmann, Marcel Aeschlimann

Patent number: 8403938Abstract: 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: GrantFiled: October 29, 2008Date of Patent: March 26, 2013Assignees: Woodwelding AG, Stryker Trauma GmbHInventors: Marcel Aeschlimann, Laurent Torriani, Mario Lehmann, Jörg Mayer, Richard Lum, Kyle Craig Pilgeram, Michael Baycura, Lisa Ballou
