  • Publication number: 20250143890
    Abstract: 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.

  • Publication number: 20250114128
    Abstract: A transverse connector for interconnecting first and second spine rods. The connector has a first connecting member connectable with the first spine rod, a second connecting member connectable with the second spine rod and fixed a set distance from the first connecting member, and a coupler integrally attached to only one of the first and second connecting members, and configured to angularly couple the first and second connecting members together such that an angle of deployment between the first connecting rod and the second connecting rod is adjustable. The connector has a fastener of the coupler which is configured to fix the angle of deployment in any one of a plurality of angular positions.

  • Publication number: 20250049487
    Abstract: A bone cement mixing and dispensing system and method for mixing and delivering bone cement therefrom. The system has a mixing container for holding a bone cement mixture, the mixing container extending along an axial length and having opposed first and second ends, the first end comprising a downstream opening for dispensing the bone cement downstream from the mixing container; a mixing element movably disposed within the mixing container; and a plunger comprising a piston movably disposed within the mixing container. In this system, with a first coupling, the mixing element moves by assistance of a motor along the axial length of the mixing container without translation of the plunger to mix the bone cement. In this system, with a second coupling, the mixing element and plunger are driven together along the axial length of the mixing container.

  • Publication number: 20240330562
    Abstract: A plurality of design iterations are executed for a flow to design a circuit. The design flow includes a sequence of at least two stages. Each stage produces an output design of the circuit from an input design of the circuit, in accordance with parameters for that stage. The design iterations select parameter values for slices of one or more stages of the design flow. In the design iterations for at least one of the slices, parameter values for a non-final stage of the design flow are selected based on a final quality of result (QoR) of the design flow. The design iterations for this slice are adapted based on final QoRs produced by the design iterations.

  • Patent number: 12036130
    Abstract: A surgical implant and a surgical kit. The surgical implant has a body having at least one interior surface, the body forming a peripheral support for the implant. The surgical implant has a porous insert comprised of a porous material, having at least one axially-extending hole, and attached to the body along the at least one interior surface such that the porous material extends across a height of the body. The porous insert has a locking mechanism formed in the porous insert or extending from the porous insert, the locking mechanism minimizing movement of the porous insert from within the body. The surgical kit includes the surgical implant and an intervertebral insertion device.

    Abstract: 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 disposed in a center of the nose member connects to the actuator for centering the nose member with 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.

  • Patent number: 11911289
    Abstract: An expandable screw for orthopedic insertion and expansion between a collapsed state and an expanded state. The screw has an upper externally-threaded body segment, a lower externally-threaded body segment opposite the upper external thread segments, and an expansion member extending along a longitudinal axis thereof. The expansion member connecting the upper externally-threaded body segment to the lower externally-threaded body segment, and configured during the expansion between the collapsed state and the expanded state to separate the upper externally-threaded body segment from the lower externally-threaded body segment.

  • Publication number: 20240058039
    Abstract: A modular screw assembly for use in stabilizing a spinal column. The assembly has a fastener which couples to a screw head of a bone anchor, a screw head coupler, a retaining ring, and a friction ring. The fastener houses the screw head coupler, the retaining ring, and the friction ring. Translation of the fastener by the screw head results in the retaining ring elastically deforming and then snapping around the screw head.
