An insertion instrument for inserting an implant includes an elongated main body having a proximal handle and a distal portion that selectively couples to the implant. A plunger is slidably engaged in a central passage of the elongated main body to fix the implant to the elongated main body. A hex nut driver is concentrically located about the plunger and elongated main body to deploy an actuation plunger of the implant. The proximal handle portion of the main body includes a staggered path therethrough for accepting a tab of the plunger therein. Advancement and retraction of the plunger tab within the staggered path alternates the insertion instrument between an unlocked position to mount the implant on the distal portion, a locked position to lock the implant on the distal portion, and a deployed position configured to secure the implant in position.

An implant includes a first support, a second support rotatably coupled to the first support along a distal end of the implant, and a control assembly configured to move the implant between at least a first, collapsed orientation and a second, expanded orientation, the control assembly includes a control driver coupled to the first support and comprising a head and a shaft, the control driver configured to control relative movement between the first support and the second support, a control member configured to move along the shaft of the control driver, and a first linkage hingedly coupled to the control member and the second support, wherein movement of the control member causes the first support to move relative to the second support.

An expandable intervertebral fusion implant, including an inferior component, including a first top surface, a first bottom surface, a first end including a first worm rotatably arranged therein, the first worm including a through-hole operatively arranged to allow material to be injected therethrough and into a central hole of expandable intervertebral fusion implant, and a second end including a second worm rotatably arranged therein, a superior component, including a second top surface, a second bottom surface, a third end, and a fourth end, and a first expansion mechanism including a first screw, the first screw including a first bottom end connected to the inferior component and a first top end connected to the superior component, wherein as the first worm is rotated in a first circumferential direction, the first screw rotates in a second circumferential direction and the superior component is displaced relative to the inferior component.

The present disclosure provides for spinal implants and plates including, for example, expandable plates deployable between a contracted position and an expanded position. The expandable plate may include an expandable body including a first portion and a second portion. The first portion may include a receiving cavity facing the proximal end, and a first through aperture extending in the proximal-to-distal direction. The second portion may include a lower end having a size and shape that corresponds to the receiving cavity, and a second through aperture extending in the proximal-to-distal direction. The expandable plate may include a locking screw and a nut. In at least some embodiments, in a locked position, the locking screw extends through the first through aperture and second through aperture, and is secured to the nut. In various embodiments, in an expanded position the first portion and second portion are farther away from one another relative to a contracted position.

A surgical implant system includes a surgical implant for securing adjacent vertebrae of a spine to each other. The surgical implant includes a spacer having at least one implant eyelet. The surgical implant system also includes at least one vertebral anchor configured for insertion through the at least one implant eyelet to fasten the surgical implant to the spine. The vertebral anchor has a tip portion, a head portion, an elongate shank extending from the head portion, and an elongate fin extending from the head portion and along a surface of the elongate shank. The elongate shank and the elongate fin form a generally t-shaped cross-section.

An implantable prosthesis that includes a biased coiling member and a conforming coiling member. The biased coiling member may be biased to curve from a substantially linear configuration to a nonlinear configuration. The conforming coiling member may be engaged with and curved by the biased coiling member from the substantially linear configuration to the nonlinear configuration. The biased coiling member may define a longitudinal axis when in the substantially linear configuration. The biased coiling member and the conforming coiling member may move relative to each other along the longitudinal axis. The prosthesis may be implanted in a surgical procedure that minimizes incision sizes and may be considered less invasive than typical implant procedures, especially spinal implant procedures.

A device and methods for intervertebral spinal fusion of adjacent intervertebral bodies. An intervertebral spacer is positioned within a narrow disc space between adjacent intervertebral bodies of a patient. The spacer is arranged with upper and lower guides. The guides are adapted to simultaneously guide the deployment of upper and lower anchors of an anchoring device into their respective intervertebral bodies. The spacer is also adapted to lock the upper and lower anchors to the spacer in the deployed position.

A central inflatable distractor and a perimeter balloon are inserted into the disc space in uninflated configurations. The central inflatable distractor is then expanded, thereby distracting the vertebral endplates to the controlled height of the central inflatable distractor. The perimeter balloon is then inflated with a curable substance. The perimeter balloon expands as it is filled with the curable substance and conforms to the void remaining in the disc space around the central inflatable distractor, thereby creating a horseshoe shape. Once the flowable material in the perimeter balloon has cured, the central inflated distractor can be deflated and removed. The remaining void (or inner space) is then packed with graft for fusion.

An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (˜16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (˜5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, “ultra-MIS” techniques.

A distraction device includes a cage distractor, two distractor blades, an inserter positioner, and a clip inserter. The cage distractor is selectively securable to the two distractor blades and includes two distractor housings moveable relative to one another. The inserter positioner is selectively securable to the two distractor blades and include a center member that is centered between the distractor blades when the inserter positioner is secured to the two distractor blades. The clip inserter is configured to secure a clip to a distal end thereof and is slidable through the center member to secure the clip to a cage distracted by the movement of the two distractor housings away from one another. The clip maintaining the distraction of the cage.
