  • Patent number: 10342587
    Abstract: A pedicle anchor device is equipped for being used like a pedicle screw, i.e. for being implanted in the vertebra from dorsal direction (but generally at an angle to the sagittal plane, slightly inward towards the sagittal plane) through the pedicle so that a distal portion of the device protrudes into the vertebral body. The pedicle anchor device includes a pedicle anchor device body with a head portion, a shaft portion and a longitudinal bore that extends from a proximal end of the pedicle anchor device body and has a hole or a plurality of holes from the longitudinal bore outward, for example radially outward.

  • Patent number: 10335219
    Abstract: In a human or animal patient, two bone portions separated by a cut or fracture are stabilized in a desired position relative to each other by bringing the two bone portions into this desired position, by pulling them against each other, by providing an opening having a mouth on a bone surface and reaching across the cut or fracture and walls in both bone portions, by inserting an implant into the opening and anchoring the implant in the walls of the opening with the aid of a material having thermoplastic properties and energy transmitted into the implant for in situ liquefaction of at least part of the material having thermoplastic properties. One exemplary application of the stabilizing procedure concerns the two tibial bone portions separated by tibial plateau leveling osteotomy in a canine patient suffering from cranial cruciate ligament damage or rupture in a stifle joint.

  • Patent number: 10271943
    Abstract: A soft tissue graft suitable for replacing a tendon or ligament is fastened in a bone opening provided in a human or animal patient by press-fitting an end portion of the graft and a fastener into the bone opening such that the graft end portion is pressed against a first portion of the bone wall inside the bone opening. The fastener is anchored in a second portion of the bone wall by liquefying a material having thermoplastic properties by the fastener and making the fastener penetrate into the bone wall. An end portion of the graft is tied to the fastener with the aid of at least one suture extending from the graft end portion. Tying is carried out after anchoring, during anchoring or between anchoring and press-fitting. The tied connection between the fastener and the graft end portion successfully counteracts potential graft slipping.

  • Patent number: 10271884
    Abstract: 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 includes 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 contact 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.

  • Publication number: 20180304543
    Abstract: A method of mechanically securing a first object including a thermoplastic material in a solid state to a second object with a generally flat sheet portion, with a perforation of the sheet portion, and with the sheet portion having an edge along the perforation is provided, wherein the first object is positioned relative to the second object so that the edge is in contact with the thermoplastic material and wherein mechanical vibration energy is coupled into the assembly including the first and second objects until a flow portion of the thermoplastic material due to friction heat generated between the edge and the thermoplastic material becomes flowable and flows around the edge to at least partially embed the edge in the thermoplastic material. After the mechanical vibration stops, the thermoplastic material is caused to re-solidify, whereby the re-solidified thermoplastic material at least partially embedding the edge anchors the first object in the second object.

  • Publication number: 20180215105
    Abstract: A method of bonding a second object to a first object includes: providing the first object, which includes a thermoplastic liquefiable material in a solid state; providing the second object, which includes a surface portion that has a coupling structure with an undercut such that the second object can make a positive-fit connection with the first object; and pressing the second object against the first object with a tool that is in physical contact with a coupling-in structure of the second object while mechanical vibrations are coupled into the tool. The step of pressing and coupling vibrations into the tool continues until a flow portion of the thermoplastic material of the first object is liquefied and flows into the coupling structures of the second object. Thereafter, the thermoplastic material of the first object is permitted to re-solidify to yield a positive-fit connection between the first and second objects.
