Systems for distracting a facet joint and positioning a permanent implant in the joint are disclosed. The implants serve to retain a distracted position of the facet joint which is achieved with positioning of the leading end of a distraction tool in the facet joint and then distracting or enlarging the joint a desired amount. The permanent implant could be part of the distraction mechanism which can be separated from the delivery tool once the joint has been distracted or an auxiliary implant may be positioned before the distraction mechanism is removed from the distracted joint. The permanent implants can be solid, mechanical devices that may have fixation means thereon to hold them in place or injected fluids such as hydrogels or fluids confined within balloons.

A steerable expandable implant including a base member, an adjustable member coupled to the base member, the adjustable member movable between a collapsed position and an expanded position, a pivot member rotatably received by the base member and configured to receive a tool such that the tool and the pivot member are rotatable relative to the base member between a first position and a second position, wherein the pivot member is translationally fixed relative to the base member, and a first control member received by the base member, wherein manipulation of the first control member causes the adjustable member to move between the collapsed position and the expanded position.

An interbody tool may include an upper portion with an upper contact surface and a plurality of upper legs; a lower portion with a lower contact surface and a plurality of lower legs, each of the lower legs moveably connected to one of the upper legs; a plurality of gauges, each gauge configured to measure a position of one of the plurality of upper legs relative to a corresponding one of the plurality of lower legs; at least one actuator configured to selectively push the upper portion away from the lower portion; and at least one sensor for measuring a force exerted by the at least one actuator.

Expandable fusion devices, systems, instruments, and methods thereof. The expandable fusion implant may include an upper endplate assembly and a lower endplate assembly. The upper and lower endplate assemblies may be configured to expand in width. A rotatable actuator may move one or more driving ramps, which mate with an upper ramp and a lower ramp, respectively. The actuator may cause independent movement of one or more of the driving ramps, thereby causing an expansion in height of the upper and lower endplate assemblies.

Expandable fusion devices, systems, and methods thereof. The expandable implant may include first and second lateral legs and link plates pivotably joined between them. The lateral legs may include upper and lower endplates configured to engage adjacent vertebrae, an actuator assembly including a rotatable actuator having a shaft and a rotatable nut, and driving ramps positioned along the shaft of the actuator. The actuator assembly may cause independent movement of one or more of the driving ramps, thereby causing an expansion in height of the upper and lower endplates of the lateral legs and passive expansion of the connected link plates.

An expandable intervertebral implant having an upper body portion, a lower body portion opposite the upper body portion, a wedge member connecting the upper body portion to the lower body portion, a nose member having a tapered distal end and a proximal end opposite the distal end, and an actuator disposed between the nose member and the wedge member, for translation of the wedge member along a longitudinal axis of the implant. A pin connects to the actuator for positioning the nose member relative to the actuator. Translation of the wedge member along the longitudinal axis of the implant displaces the upper body portion and the lower body portion away from each other, thereby expanding the intervertebral implant.

Embodiments herein are generally directed to spinal implants, systems, apparatuses, and components thereof that can be used in spinal fusion and/or stabilization procedures, as well as methods of installation. The spinal implants may include an intervertebral spacer and a plate member.

A surgical implant and a surgical kit. The surgical implant has a body portion comprising a first hole formed in an exterior surface of the body portion, a second hole adjacent the first hole, and at least one through-hole within the body portion and extending entirely thought a depth of the body portion extending entirely thought a depth of the body portion. The implant has a central opening abutting the body portion and extending through the body portion. The first hole has a first sidewall and a first cavity in the body portion, the second hole has a second sidewall and a second cavity in the body portion, and the first cavity and the second cavity have an interconnected opening there between. The surgical kit includes the surgical implant and an intervertebral insertion device.

A spinal implant includes a chassis extending along a first axis and including a first thread. A first member extends along a second axis and is pivotably coupled to the chassis. A second member extends along a third axis between and is pivotably coupled to the chassis. A rack includes opposite top and bottom surfaces. A first spur is coupled to the first member such that the first spur engages the top surface. A second spur is coupled to the second member such that the second spur engages the bottom surface. An actuator includes second thread that engages the first thread such that rotation of the actuator move the implant between a first orientation in which the second and third axes extend parallel to the first axis and a second orientation in which the second and third axes extends at an acute angle relative to the first axis.

A multi-section expandable device includes an expansion module, a first push member and a second push member disposed at front and rear ends of the expansion module, and a bolt screwedly connected to the first and second push members. When the bolt is tightened, the first push member and the second push member are pushed to approach each other so as to push the expansion module to generate a first-stage expansion and a second-stage expansion. The first-stage expansion enables the expansion module to expand laterally so as to adjust its width. The second-stage expansion is performed after the expansion module is laterally expanded to have a maximum width, so that the expansion module is longitudinally expanded to adjust its height. The multi-section expandable device not only has better support effect, but also avoids the wear of the contact surfaces of the vertebrae.
