  • Publication number: 20180125482
    Abstract: A device for fixing a first and a second tissue part or a tissue part and an implant part to each other is provided, providing a fastener including a thermoplastic material and a fastening instrument. The fastening instrument includes a first instrument component with a first contact surface facing toward a distal side and a second instrument component has a foot with a second contact surface distally of the first contact surface and facing toward a proximal side. The first instrument component and the second instrument component are displaceable with respect to each other, so that the fastener is compressible between the first and second contact surfaces by application of a relative force between the components. The instrument also includes an energy source for coupling mechanical energy into one of the instrument components to soften and/or melt an end portion of the fastener.

  • Publication number: 20180111325
    Abstract: A profile body of a not liquefiable material is used as a connecting element between a first object and a second object. The profile body may especially be metallic and/or may be bendable. The profile body, in contrast to a conventional wire, however, has a shape defining a first and a second undercut. The method includes embedding the profile body in the second object so that the second undercut is within material of the second object, and embedding the profile body within material of the first object so that the first undercut is within the first object, and wherein at least embedding of the profile body in the first object is caused by mechanical energy impinging on the first object and/or on the second object while the first object and the second object are pressed against each other.

  • Publication number: 20180000592
    Abstract: The fusion device for fusing a synovial joint of a human or animal patient, in particular a human facet joint, finger joint or toe joint, includes two pin-shaped anchorage portions and arranged therebetween a stabilization portion. The anchorage portions include a thermoplastic material which is liquefiable by mechanical vibration. The stabilization portion preferably has a surface which is equipped for enhancing osseointegration. The anchorage portions have a greater thickness and a greater depth than the stabilization portion. Then the fusion device is pushed between the articular surfaces and mechanical vibration, in particular ultrasonic vibration, is applied to the proximal face of the fusion device. Thereby the liquefiable material is liquefied where in contact with the bone tissue and penetrates into the bone tissue, where after re-solidification it constitutes a positive fit connection between the fusion device and the bone tissue.

  • Publication number: 20170297271
    Abstract: A joining element has an anchoring portion for in-depth anchoring in the object and a head portion arranged proximally of the anchoring portion with respect to an insertion axis. The head portion has a lateral outer surface that has a structure that is well-defined, especially within tight tolerances. The joining element is positioned relative to an object of a non-liquefiable material such that the anchoring portion reaches into an opening of the object or is placed adjacent a mouth thereof. Then, the joining element is pressed towards a distal direction, to press the anchoring portion into the opening, while mechanical vibration energy is coupled into the joining element by a tool, in an amount and for a time sufficient for liquefaction of a portion of the thermoplastic material to cause interpenetration of the thermoplastic material into structures of the object.
