A lumbar interbody fusion device includes a first wing, a second wing, and a bridge. The bridge has an arcuate resting shape and include a first end connected to the first wing, a second end connected to the second wing, and at least one aperture extending through the bridge in a radial direction relative to the arcuate resting shape of the bridge. The bridge is elastically deformable such that a distance between the first wing and the second wing may vary according to elastic deformation of the bridge.

The present disclosure relates to an interspinous omnidirectional dynamic stabilization device, including a first fixing part, a second fixing part, a connecting structure and an elastic structure, wherein the first fixing part and the second fixing part are fixedly connected to each other through the connecting structure and elastic structure, the bottoms of the first fixing part and the second fixing part are provided with one or more barbs, the elastic structure is made up of one or more U-shaped structures connected to each other, and the first fixing part and the second fixing part are provided with fixing holes respectively. The device is able to provide the maximum matching for the mobility in all directions, according to the requirements on the physiological activities of the human body, without causing stabilizing structures to be relatively displaced, or loosen and fall off. In addition, the device has a reasonably designed structure, with a small size. The device can be firmly fixed, and have a strong ability of elasticity attenuation resistance. In the device, the prosthesis has strong vertical support force at the bottom of the spinous process after implantation. Moreover, the device is fixed to the spinous processes and lamina, with the elastic structure attached to the spinous processes on either side of an interspinous space, and the bottom of the prosthesis is not forced to be close to the spinal dura mater, to reduce the risk of damaging the spinal dura mate during or after surgery.

The invention relates to a fastening device for an implant that is elastically deformable by stress, the length of the device in the unstressed state being less than that of the device in the stressed state, and the diameter of the device in the unstressed state being greater than that of the device in the stressed state, and to a kit comprising it.

Methods and apparatus for delivering a sheet-like implant to a target site including a means of deploying and orienting the sheet-like implant within the body.

An implant may include a body having a first portion and a second portion and a structural member having a central member curve. In addition, the structural member may be exposed on an outer surface of the implant. Further, the central member curve may include a winding segment, and the winding segment of the central member curve may wind around a fixed path extending from the first portion of the body to the second portion of the body. Also, the central member curve may make one or more full turns around the fixed path. And, the structural member may have a member diameter at the winding segment, wherein the winding segment has a winding diameter corresponding with the full turn around the fixed path and the member diameter is greater than the winding diameter.

Augmentation material having a wire and, in axial alignment along the wire, a plurality of groups of axially adjacent connecting elements that extend radially from the wire, wherein the connecting elements are designed such that, when a first group from the plurality of groups is pressed together with a further group from the plurality of groups, the connecting element of the two groups can be connected to one another in a positive-locking and/or friction-locking manner.

Various embodiments provide systems and methods for repairing or replacing intervertebral discs as a treatment for derangements. Systems and methods may comprise an inter vertebral disc implant for deployment into an intervertebral disc space wherein the nucleus has been at least partially evacuated from the deranged intervertebral disc. The intervertebral disc implant may be intraoperatively and postoperatively filled and/or re-filled with a growth matrix. The intervertebral disc implant may be differentially permeable to the growth matrix to provide directional growth and/or diffusion of the growth matrix to restore height to the intervertebral disc space. Systems and methods may further comprise an implant delivery device for deploying the intervertebral disc implant into the intervertebral disc space.
