Patent number: 11432812Abstract: A knotless anchor assembly method and device comprising an anchor and a compression member, wherein the anchor further comprises a pilot tip and anchor body. During procedures to tension the knotless anchor assembly, the anchor is driven into bone or other surface or component, and the tension member is urged into the anchor body recess. The compression member is secured in the anchor body to lock the tension member in place. The knotless anchor assembly gives the surgeon or user the ability to optimize tensioning by having the ability to change tension in the tension member by adjusting the compression member during or after the repair.Type: GrantFiled: May 13, 2019Date of Patent: September 6, 2022Assignee: Dunamis Medical Technologies, LLCInventors: Prithviraj Chavan, Eugene Shoshtaev

Patent number: 11285018Abstract: Expandable spinal fusion devices, systems, and methods of using them are provided, and they can be inserted in a subject in a collapsed state through a small surgical corridor, and the expand cephalocaudal only, transverse only, or in both directions, in which direction of expansion can also be obtained independently, if desired, after the insertion. These inventions are valuable in reducing risk and surgical complexity, allowing for an on-the-fly selection of a desirable width footprint, a desired control of height expansion through a gradual cephalocaudal expansion, and a desired control of the alignment of the adjacent vertebral bodies. Devices, systems, and methods are also offered to provide a desired control of the contact area desired between the device and the upper and lower vertebral endplates achieved, for example, using an interdigitated endplate system.Type: GrantFiled: March 1, 2019Date of Patent: March 29, 2022Assignee: INTEGRITY IMPLANTS INC.Inventor: Eugene Shoshtaev

Publication number: 20220015923Abstract: A variety of expandable cage improvements are provided. The cages can have a width expansion assembly that operates independently of a height expansion assembly and the wedges and ramps do not need to make contact with each other. Wedges, or movable spacers with pivotal link connections, can be used, and any portion of the cage can be expanded in width or in height in an amount that differs from other portions of the cage to provide any of a multitude of desired cage shapes. Interdigitating fingers, slidable and/or pivoting, are provided to distribute stresses over a vertebral endplate as desired.Type: ApplicationFiled: July 20, 2021Publication date: January 20, 2022Inventor: Eugene Shoshtaev

Publication number: 20210401588Abstract: A spine implant for a TLIF surgical procedure is configured to be guided into place during implantation in conjunction with a complementary insertion instrument. The cage of the implant is constrained to a limited range of rotation about a pivoting post carried by the cage. The insertion instrument is configured to hold the post while controllably rotating the cage relative to the post in order to angularly position the implant during implantation. Range of rotational motion is controlled by the configuration of an opening in and end of the cage and a groove in the pivot post. A retaining pin of the implant extends from the cage into the groove of the post to rotationally connect the cage to the post.Type: ApplicationFiled: September 3, 2021Publication date: December 30, 2021Applicant: Life Spine, Inc.Inventors: Gregory PALAGI, Eugene SHOSHTAEV, Madeline C. WOLTERS, David T. MEHL, Daniel P. PREDICK, Casey RICE
