  • Publication number: 20200367948
    Abstract: A modular implant system, such as a spinal implant system, having an implant part, for example a (spinal) plate, and at least one fastener, wherein the implant part has a fastener receiving opening. The system also includes thermoplastic material, the thermoplastic material being equipped for being liquefied by mechanical vibration, especially ultrasonic vibration energy. The fastener receiving opening and the fastener can be shaped so that the fastener can be inserted relative to the implant part at a variable angle. The fastener, the plate and the thermoplastic material are equipped for the thermoplastic material, after re-solidification, to secure the fastener against at least one of an axial (back-out) movement of the fastener, a rotation of the fastener relative to the implant part, a variation of the angle of the fastener relative to the implant part.

  • Publication number: 20200353695
    Abstract: Methods of bonding a first object to a second object, including the steps of: providing the second object having a protrusion; providing the first object having a thermoplastic material; positioning the first object relative to the second object such that an assembly of the first and the second object is formed; applying a relative force between the second and first objects and applying mechanical vibration to the assembly of the first and the second object until at least a flow portion of the thermoplastic material becomes flowable and flows around the protrusion; and causing the thermoplastic material to re-solidify. The first object may be a connecting element including a feedthrough, wherein the second object has a corresponding opening. The protrusion may be deformed such that the protrusion has an undercut relative to an axis along which the first and second objects are pressed against each other.

  • Patent number: 10807313
    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.

  • Patent number: 10780644
    Abstract: A method for joining two objects by anchoring an insert portion provided on a first object in an opening provided on a second object. The anchorage is achieved by liquefaction of a thermoplastic material and interpenetration of the liquefied material and a penetrable material, the two materials being arranged on opposite surfaces of the insert portion and the wall of the opening. During the step of inserting the insert portion in the opening and/or during anchorage a clamping force is applied to opposing surfaces of the second object to prevent the second object from cracking or bulging.

  • Patent number: 10758372
    Abstract: A method of implanting a contact implant includes providing the contact implant, providing a plurality of anchoring implants having a plurality of through openings, placing the contact implant at an implantation location, and introducing a first one of the anchoring implants through a first of the plurality of through openings. Mechanical oscillations are applied, along a first axis, to the first one of the anchoring implants, thereby causing thermoplastic material of the implant to liquefy and interpenetrate portions of the tissue. A second one of the anchoring implants is introduced through a second one of the through openings to bring it in contact with the live tissue. Mechanical oscillations are applied, along a second axis, to the second one of the anchoring implants to cause thermoplastic material to be liquefied. The first and first and second axes are at a nonzero angle to each other.

  • Patent number: 10722369
    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.
