Patent number: 12133667Abstract: The self-contouring plate system for bone fractures allows a surgeon to bridge a bone fracture, primarily in bones of complex shape where the use of plates or screws is difficult. The self-contouring plate is formed from a series of similar or identical rigid elements, the elements able to bend and rotate with respect to each other. This flexibility is initially helpful as the surgeon contours the device to the shape of the bone. When the desired shape is reached, the elements are locked into place. The length of device is adjusted by adding or removing elements, much like a necklace. Each element of the self-contouring plate includes a ball that extends away from a body, a cavity for receiving the ball of the neighboring plate, and a screw to compress the ball within the cavity.Type: GrantFiled: June 6, 2022Date of Patent: November 5, 2024Inventors: Yasser Nadim, Lance Fagan

Patent number: 12102314Abstract: The system includes a frame composed of materials and geometry allowing selective deformation in a plane perpendicular to a patient's anatomy at the surgical site but resisting deformation in a plane parallel to the anatomy. The frame is connected to stabilizing features and sheets, which are attached to adhesive to secure the frame to the patient. The features, sheets, and adhesive layers extend both into and beyond the frame. An integrated sheet covers the prospective incision site on the patient. When positioned at the site, the frame conforms to the patient. Anchor points are distributed along the frame to reversibly secure and provide a stable base for surgical retractors, even when unilaterally applied. By adaptable positioning and design of the stabilizing members and adhesive layers on the frame, the system is able to provide optimal tractional stability when experiencing tensile loads in myriad surgical environments including ophthalmic and spinal surgery.Type: GrantFiled: September 25, 2023Date of Patent: October 1, 2024Assignee: Biophyx Surgical, Inc.Inventors: Robert Richards, Stephen Maguire

Patent number: 12089837Abstract: A surgical staple insertion system for compressing bone fragments includes a staple and an insertion tool. The staple has first and second legs and an elastically deformable bridge monolithically formed with the first and second legs. In a relaxed configuration, the free ends of the first and second legs are positioned closer to one another than are portions of the first and second legs connected to the bridge. The insertion tool retains the bridge in an elastically deformed configuration with the legs positioned relatively farther apart from one another during at least portion of the step of implantation of the staple. Then, the insertion tool is released from the staple so that the bone fragments between the legs are subject to compression.Type: GrantFiled: May 8, 2023Date of Patent: September 17, 2024Assignee: Biedermann Technologies GmbH & Co.
