    Abstract: A surgical implant includes a deployable, retractable, or removable ramped nose. During insertion of the implant, the ramped nose is deployed such that the ramped nose can serve to distract a space into which the implant is inserted. At some point during or after insertion, the ramped nose can be collapsed and removed or retracted so that it does not extend beyond the space into which the implant is inserted, while the implant extends at full height throughout the space into which the implant is inserted. The implant includes an implant body having a deployable ramped nose adapted to selectively extend from the body and transition from a first height proximate the implant body to a second, shorter, height distal from the implant body. The deployable ramped nose is adapted to distract an implant site upon insertion of the implantable medical device.

The method includes combining undifferentiated cells, such as pluripotent or multipotent stem cells, with a biomaterial to make multiple undifferentiated or naïve subunits, exposing the undifferentiated or naïve subunits to different cell culture environments for induction of differentiation towards different lineages as required by that complex tissue, and combining the then functional subunits with or without the undifferentiated subunits. The differentiated subunits thus combined can be cultured under biological, chemical, and/or physical culture conditions suitable to fine-tune the structural and functional properties of the bioengineered complex tissue to form a bioengineered tissue graft that mimics the structural and functional characteristics of native complex tissue. The bioengineered tissue graft can then used to replace dysfunctional tissue.

    Abstract: The embodiments provide various interbody fusion spacers, or cages, for insertion between adjacent vertebrae. These intervertebral cages can restore and maintain intervertebral height of the spinal segment to be treated, and stabilize the spine by restoring sagittal balance and alignment. The cages may have a first, insertion configuration characterized by a reduced size at each of their insertion ends to facilitate insertion through a narrow access passage and into the intervertebral space. The cages may be expanded to a second, expanded size once implanted. In their second configuration, the cages are able to maintain the proper disc height and stabilize the spine by restoring sagittal balance and alignment. The intervertebral cages are configured to be able to adjust the angle of lordosis, and can accommodate larger lodortic angles in their second, expanded configuration. Further, these cages may promote fusion to further enhance spine stability by immobilizing the adjacent vertebral bodies.

  • Patent number: 11452607
    Abstract: An expandable interspinous spacer implant that is configured to be inserted into an interspinous space that is defined between a spinous process of a superior vertebral body and a spinous process of an inferior vertebral body is provided. The implant may include a superior housing, an inferior housing, and a distracting member. The superior housing may have an outer surface that is configured to engage the spinous process of the superior vertebral body and the inferior housing may have an outer surface that is configured to engage the spinous process of the inferior vertebral body. The distracting member may be disposed between the superior and inferior housings, such that activation of the distracting member distracts the superior and inferior housings apart from each other.

  • Patent number: 11452616
    Abstract: A bone fusion method, apparatus and device for insertion between bones that are to be fused together and/or in place of one or more of the bones, such as, for example, the vertebrae of a spinal column. The bone fusion device comprises one or more extendable plates having a central rib. The bone fusion device includes one or more support channels configured to receive an insertion instrument that is then secured to the bone fusion device via a coupling mechanism. As a result, the coupled device is able to be securely positioned between vertebrae using the insertion instrument with minimal risk of slippage.

  • Patent number: 11446155
    Abstract: An intervertebral implant that iterates between collapsed and expanded configurations includes first and second plates spaced from one another along a first direction and defining bone-contacting surfaces facing away from each other along the first direction. An expansion assembly is positioned between the plates with respect to the first direction and includes a first support wedge that supports the first plate and defines a first ramp and a second support wedge that supports the second plate and defines second and third ramps. The expansion assembly includes an expansion wedge defining a fourth ramp. The first, second, third, and fourth ramps are each inclined with respect to a second direction that is substantially perpendicular to the first direction. At least one of the first and second support wedges is slidable along the respective supported first or second plate.

  • Patent number: 11446156
    Abstract: An expandable intervertebral implant includes a first endplate and a endplate, a first wedge member and a second wedge member spaced from the first wedge member that couple the first and second plates together. The first and second wedge members configured to move between a first collapsed position and a second expansion position. The implant includes an actuation member coupled to the first wedge member and the second wedge member. The first and second wedge members can be coupled to the upper and lower endplates at guide members that are asymmetric. An instrument can be coupled to the implant so as to provide a force to the actuation member that causes the wedge members to move between the collapsed position and the expansion position.

  • Patent number: 11439517
    Abstract: A bone fusion device for insertion between bones that are to be fused together, such as, for example, the vertebrae of a spinal column. The bone fusion device comprises at least one extendable tab and one or more tab extension assemblies. Each tab extension assembly is able to be adjusted in order to individually control the extension or contraction of a side of the tab thereby enabling adjustment of the height and/or angle of the tab with respect to the body of the bone fusion device. Each tab extension assembly is able to be individually adjusted such that the side controlled by each assembly is raised or lowered until the desired tab angle is achieved. The tab is advantageously positioned and angled to correspond to the vertebrae to help brace the device until the bone has fused.

  • Patent number: 11426286
    Abstract: An intervertebral implant is configured to be implanted in an intervertebral space in a first initial configuration. Subsequently, an actuator is configured to be driven in an actuation direction such that the actuator urges the implant to expand along a first expansion direction. Once the implant has been fully expanded along the first expansion direction, the actuator is configured to be further driven in the actuation direction so as to expand the implant in a second expansion direction that is perpendicular to the first expansion direction.
