  • Patent number: 10709487
    Abstract: A graft or prosthetic element suitable e.g. for replacing a tendon or ligament is fastened in a bone tunnel or blind opening with the aid of a fastener. In a first step, the graft or prosthetic element is press-fitted in the tunnel or opening by forcing the fastener into the opening or by positioning the fastener in the opening and then expanding it, wherein the fastener is in contact with the graft or prosthetic element and with the bone wall of the tunnel or blind opening. In a second step, the fastener is anchored in the bone wall of the tunnel or blind opening with the aid of a liquefiable material which is liquefied in the vicinity of the bone wall where it is in contact with the fastener and by making the liquefied material penetrate into the bone wall.

  • Patent number: 10546767
    Abstract: In various embodiments, a wafer box is provided. The wafer box may include a housing with a receiving space for receiving a stack comprising a plurality of wafers, each arranged above a housing base. The wafers are to be arranged with their main surfaces parallel to the housing base. The receiving space is delimited by the housing base and side walls arranged thereon. The wafer box may further include at least one base opening, arranged in the housing base, for receiving a guide structure of a wafer stacking aid. The guide structure is to be arranged in such a way that, on a side of the housing base on which the side walls are arranged, it extends out of the housing base in order to limit tilting of a wafer raised or lowered in the receiving space in a manner guided by the guide structure.

  • Patent number: 10390957
    Abstract: A human or animal joint is treated by introduction of a device between the suitably prepared articulating surfaces of the joint, and the device is anchored in both these articular surfaces with a material having thermoplastic properties. For allowing at least limited articulation of the joint after implantation, the device includes two articulating portions, wherein one of the articulating portions is anchored in each articulating surfaces of the joint. On implantation a proximal face of the device is contacted with a vibrating tool and the vibration is transmitted through parts of the device to locations in which the material having thermoplastic properties is near the bone tissue of the articulating surfaces of the joint and in which liquefaction is desired. The liquefied material penetrates the bone tissue and, on re-solidification forms a positive fit connection between the device and the bone tissue.

  • Publication number: 20190133777
    Abstract: A spine stabilization device having an interbody spacer shaped to be inserted between a vertebral body of an upper vertebra and a vertebral body of a lower vertebra. The device further includes a fixation device to be inserted after placement of the interbody spacer, the fixation device having a support portion securing the interbody spacer against escaping from between the vertebral bodies into a ventral direction. The support portion rests against a portion of an anterior surface of the interbody spacer, and includes an anchor.

  • 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.
