  • Patent number: 10912653
    Abstract: An intervertebral scaffolding system is provided having a laterovertically-expanding frame operable for a reversible collapse from an expanded state into a collapsed state, the laterovertically-expanding frame having a stabilizer, one or more tensioners, or a combination of the stabilizer with one or more tensioners. The stabilizer slidably engages with the distal region of the laterovertically-expanding frame and both the stabilizer and the one or more tensioners are configured for retaining the laterovertically-expanding frame from a lateral movement that exceeds the expanded state, and the stabilizer can include a locking element that engages with the expansion member to lock the expansion member to the stabilizer when the expansion member is fully inserted into the frame. The expanded state, for example, can be configured to have an open graft distribution window that at least substantially closes upon the reversible collapse.

  • Patent number: 10898344
    Abstract: An expandable implant is disclosed in which the implant includes top and bottom plates having angled inner surfaces that interact with expansion members. The expansion members may be situated on an actuator, and may include at least one vertical projection. In some instances, rotation of the actuator in opposing directions about a longitudinal axis may cause the expansion members to move toward or away from one another, thereby resulting in separation of the top and bottom plates. During such expansion of the implant, the at least one vertical projection of the expansion members may be guided at least partially within a recess formed in the first or second plate. Pins may also be included with the expansion members that ride along respective slots in the plates during expansion. An insertion instrument for implanting the aforementioned implant, and methods of using the same, are also disclosed.

  • Patent number: 10842641
    Abstract: An implant (100, 200, 300, 400) includes a base (10), and a sequence of at least two segments including a first segment (12) and a last segment (14). The first segment (12) is pivotally linked to base (10). Adjacent segments are interconnected at pivotal connections (18). A bolt (20) has a threaded shaft (22) and a head (24). The threaded shaft (22) is engaged in a threaded channel (26) of the base (10) so that rotation of the bolt (20) about a central axis of the threaded shaft (22) varies a degree of overlap between the base (10) and the bolt (20). The last segment (14) and the head (24) define therebetween a spherical bearing (28). Rotation of bolt (20) thus varies a distance between spherical bearing (28) and hinge pin (16), thereby causing deflection of the sequence of segments.

  • Patent number: 10813773
    Abstract: A secondary cover plate that contacts a stand-alone fusion cage without rigidly connecting to the cage, and instead only docks against the cage (or passes through a fixation cage) and is secured into the adjacent bone. The secondary cover plate is the last item that would be added to the fixation cage construct and would at least partially cover the head of one or more angled screws. The secondary cover plate could slidably engage the fixation cage without permanently snapping into any features of the cage itself. The secondary cover plate would then be final positioned by advancing into one or more adjacent vertebral bodies. The secondary cover plate advancing step could be achieved by tapping it into place (into bone) so that it is finally secured into the bone.

  • Patent number: 10758369
    Abstract: An expandable housing for an interbody fusion system has movable tapered external helical threaded members that travel along tracking to operably engage against the top and bottom shell members, urging them apart to cause expansion in the height of the housing. In an embodiment, the tapered members are disposed in a dual arrangement such that independent engagement of the tapered members along lateral portions of the top and bottom shells cause an angular tilt to the exterior surface of the housing when the tapered members are moved to different degrees. This function permits adjustment in the angular relationship between adjacent vertebrae and assists the lordotic adjustment of the patient's spine. When the functions of the device are used in combination by the surgeon, the device provides an effective tool for in situ adjustment when performing lateral lumbar interbody fusion.

  • Patent number: 10413420
    Abstract: An intervertebral prosthesis for insertion between adjacent vertebrae includes upper and lower prosthesis plates locatable against respective vertebrae and having opposing, concavely curved recesses therein, and a core located between the plates. The core has opposed, convexly curved surfaces received in the recesses of the plates to allow the plates to slide in articulated manner over the core. The opposed surfaces of the core and the recesses of the plates have cooperating spherical curvatures. The recess of each plate surrounds a locating peg projecting centrally from the base of the recess and is bounded by an annular rim, such that the annular rims of the plates are arranged to contact one another at a predetermined limit of sliding movement of the plates over the core. The peg locates loosely in an opening located centrally in a curved surface of the core, whereby the plates can slide over the core in all directions while the peg holds the core captive.

  • Patent number: 10398567
    Abstract: An expandable, adjustable inter-body fusion device is presented. The inter-body fusion device can have a first plate, a second plate, and an insert positioned substantially therebetween the first plate and the second plate. The first plate, the second plate, and the insert define an interior cavity. Rotation of the insert relative to the first and second plates increases or decreases the distance of the first plate with respect to the second plate, effectively expanding the inter-body fusion device and increasing the volume of the interior cavity. The angle between the first plate and the second plate is selectively adjustable.

  • Patent number: 10398566
    Abstract: An adjustable spinal fusion intervertebral implant is provided that can comprise upper and lower body portions that can each have proximal and distal wedge surf aces disposed at proximal and distal ends thereof. An actuator shaft disposed intermediate the upper and lower body portions can be actuated to cause proximal and distal protrusions to converge towards each other and contact the respective ones of the proximal and distal wedge surfaces. Such contact can thereby transfer the longitudinal movement of the proximal and distal protrusions against the proximal and distal wedge surfaces to cause the separation of the upper and lower body portions, thereby expanding the intervertebral implant. The upper and lower body portions can have side portions that help facilitate linear translational movement of the upper body portion relative to the lower body portion.

  • Patent number: 10398451
    Abstract: An endoscopic pedicle probe for use during spinal surgery to form a hole in a pedicle for reception of a pedicle screw has an enlarged proximal end for cooperation with the hand of the surgeon and an elongate shaft terminating in a distal tip that may be pushed through the pedicle to form the hole. The tip may be detachable for replacement. An endoscope extends through the shaft and is connected with a monitor to enable the surgeon to visually observe the area being treated. In a preferred form a light means extends through the shaft to illuminate the area being treated, and in a further preferred form a conduit extends through the shaft to convey a fluid to flush the area being treated. In a further embodiment, two endoscopes are associated with the probe.

  • Patent number: 10350081
    Abstract: A joint spacer therapeutically maintains separation of bones of a joint. A carriage is slideably retained within the frame and has at least one ramped surface. An actuator screw is threadably engaged with the frame, and rotatably connected to the carriage, to cause the carriage to slideably move within the frame when the actuator screw is rotated. First and second endplates engage the bones of the joint, and each has at least one ramped surface that is mateable with the ramped surface of the carriage, whereby when the carriage is slideably moved by rotation of the actuator screw, the endplates ramped surface slides against the carriage ramped surface to cause the endplates to move along an axis transverse to the longitudinal axis of the frame, to increase the height of the spacer. Piercing elements are connected to the carriage to pierce bone of the joint when the carriage is moved.
