  • Publication number: 20240245527
    Abstract: The present disclosure relates to an expandable intervertebral cage (1) comprising a base (2) with a circumferential side wall (7) extending in a first direction (z) and a first bone interaction surface (5) and a stage (3) comprising a second bone interaction surface (6) arranged essentially opposite to the first bone interaction surface (5) with respect to the expandable intervertebral cage (1). An expansion mechanism (4) serves for adjusting the position of the second bone interaction surface (6) of the stage (3) with respect to the first bone interaction surface (5) of the base (2) at least in the first direction (z).

  • Patent number: 11474171
    Abstract: The present invention is directed to a system and method for performing tissue, preferably bone tissue manipulation. The system and method may include implanting markers on opposite sides of a bone, fractured bone or tissue to facilitate bone or tissue manipulation, preferably in-situ closed fracture reduction. The markers are preferably configured to be detected by one or more devices, such as, for example, a detection device so that the detection device can determine the relative relationship of the markers. The markers may also be capable of transmitting and receiving signals. An image may be captured of the bone or tissue and the attached markers. From the captured image, the orientation of each marker relative to the bone fragment may be determined. Next, the captured image may be manipulated in a virtual or simulated environment until a desired restored orientation has been achieved. The orientation of the markers in the desired restored orientation may then be determined.

  • Patent number: 10842545
    Abstract: An implant assembly includes a first implant member, a second implant member, and a contractible element that is connected between the first and second implant members. The first implant member is configured to be placed against a first bone portion, and the second implant member is configured to be placed against a second bone portion. The contractible element is fixed at a first end to one of the first and second implant members, and movable at a second end with respect to one of the first and second implant members so as to induce tension in the suture, thereby providing a compressive force against the first and second bone portions. The second end can then be fixed with respect to the first and second implant members. The contractible element can contract in length in response to bodily fluids, thereby ensuring adequate post-operative compression. An instrument is also disclosed that is configured to implant the first and second implant members adjacent the first and second bone portions, respectively.

  • Patent number: 10646349
    Abstract: An expandable implant includes an implant body defining an internal void, the implant body including a plurality of interconnected linkages. A first plurality of the linkages has an expansion characteristic that is different from a second plurality of the linkages. An expandable bladder is sized to be disposed in the internal void. The bladder defines a bore configured to receive an expansion material, such that the expansion material applies an expansion force against the bladder, which thereby applies the expansion force against the implant body so as to cause the first linkage to expand greater than the second linkage. The expandable implant can be placed in a fracture location so as to restore height to a fractured target bone.
