  • Patent number: 11090043
    Abstract: 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.

  • Patent number: 11083597
    Abstract: A system for implanting an expandable interbody implant into an intervertebral space includes an elongated tool, the distal end of which is removably securable to the implant. The proximal end of the tool has an attachment interface for detachable securement to a plurality of different modules, each of which is adapted to effectuate a different function of the delivery system. The different functions include: grasping the implant delivery tool, providing an impaction surface for driving the advancement of the implant, supplying a graft material into the implant, and actuating the expansion of the implant. One of the modules may include a fluid delivery system for supplying hydraulic fluid to expand the implant. A fluid reservoir of the fluid delivery system may be oriented transverse to the cannula that delivers the fluid to the implant. A grafting block can be used to help pre-pack the implant with graft material.

  • Patent number: 10987143
    Abstract: A flexible screw and method for non-rigid fixation between two bones. The flexible screw includes a head, and a body including a thread portion with a flexible shaft portion extending therebetween. The head has a diameter greater than that of the flexible shaft portion. The thread portion has a plurality of rigid threads while the flexible shaft portion has plurality of openings arranged in a pattern configuration. The openings extend at least partially through the flexible shaft portion. The flexible screw can be used for non-rigid fixation by inserting the thread portion in a first bone while the head is positioned on a distal side of an adjacent second bone. The flexible screw is tightened such that the flexible shaft portion extends in the joint between the first bone and the second bone. The flexible shaft portion provides stability while also adding back motility lost by the reduction in the size of the joint.
