EXPANDABLE INTERBODY FUSION DEVICE
20220280309 · 2022-09-08 · ·

An expandable intervertebral implant for an intervertebral fusion is provided. The implant includes a first endplate, a second endplate, a translation member and an auger mounted to the translation member and extending through the second endplate. The first endplate includes a sloped anterior face and a sloped posterior face. The second endplate includes a posteriorly facing sloped surface for matingly engaging the sloped anterior face of the first endplate. The translation member includes an anteriorly facing sloped surface for matingly engaging the sloped posterior face of the first endplate.

Implant with freely moveable endplates
11439516 · 2022-09-13 · ·

An interbody fusion device including pivoting endplates is disclosed. The endplates define grooves between the endplates to house sliding pins. A threaded shaft extends through the implant to connect the endplates and the sliding pins. The implant is fit to be inserted into an intervertebral disc space to pivot according to the natural angles of the adjacent vertebrae. The shaft can be rotated to adjust the sliding pins into a position to provide support to the endplates at the angle they take between the vertebrae.

Anchoring device and system for an intervertebral implant, intervertebral implant and implantation instrument

Various embodiments of intervertebral implants, anchoring devices for intervertebral implants, and implantation instrumentation are provided, along with various embodiments of methods for using one or more of the devices. Some embodiments of an anchoring device have a body comprising at least one curve and a rigid plate elongated along a longitudinal axis so that its front end enters at least one vertebra while its rear end remains in the passage of an implant. In some embodiments, the plate comprises at least one longitudinal slot separating at least one posterior portion of the plate into two branches, with at least one branch comprising at least one withdrawal stop configured to retain the device in the implant.

Anti-microbial and osteointegration nanotextured surfaces

Disclosed is a medical device having a substrate having an exposed surface and a texture over at least part of the exposed surface. The texture includes a plurality of nanofeatures that inhibit bacterial adhesion on the surface and that also inhibit bacterial growth on the surface and have a size range between about 0.01 nanometers and about 1,000 nanometers. The texture can include a plurality of nanofeatures applied thereto such that the texture has a first particle size at a first location, a second particle size at a second location, and a gradient of particle size from the first particle size to the second particle size between the first location and the second location.

System and method for spine fusion using an expandable cage
11278425 · 2022-03-22 ·

An expandable cage system for use in spinal surgery includes a top portion having an outwardly extending top arm, and a bottom portion having an outwardly extending bottom arm. The bottom arm is configured to engage with the top arm such that upon engagement, the top portion and the bottom portion are substantially restricted from movement relative to each other in an anterior-posterior direction, and in a medial-lateral direction. The expandable cage system further includes a removable shim configured to be positioned between the top portion and the bottom portion to hold the expandable cage in an expanded position within a spinal cavity.

Expandable spinal implant system and method

An expandable spinal implant is provided having a frame with a distal wall for retaining an expansion plug such that bone growth promoting material may be introduced to a proximal portion of the implant after expansion. Various implants, systems and methods are disclosed.

Expandable spinal implants

A spinal implant has proximal and distal regions, and includes upper and lower bodies. A proximal adjustment assembly is disposed between the upper and lower bodies in the proximal region of the spinal implant and is adjustably coupled to the upper and lower bodies, and a distal adjustment assembly is disposed between the upper and lower bodies in the distal region of the spinal implant and is adjustably coupled to the upper and lower bodies. The proximal and distal adjustment assemblies are independently movable with respect to each other, both concurrently and alternately, to change a vertical height of at least one of the proximal or distal regions of the spinal implant. A set screw is removably disposed within the proximal region of the spinal implant to lock the vertical height of the proximal and distal regions of the spinal implant.

Dual expandable spinal implant
11304821 · 2022-04-19 ·

Apparatus and associated methods relate to a spinal implant configured to expand both vertically and laterally at the same time when wedges coupled by a threaded post drive movable spinal implant endplates radially outward from the longitudinal axis of the threaded post, displacing the wedges and expanding the implant as the threaded post turns. In an illustrative example, the wedges may be a pair of wedges configured with dual inclined planes. The inclined planes may be, for example, disposed both vertically and laterally with respect to the threaded post longitudinal axis, permitting implant expansion both vertically and laterally simultaneously. In some examples, the wedges may be cones. Some embodiments may include an aligning support. In some samples, the aligning support is a pair of rails adapted to prevent rotation of the wedges. Various examples may advantageously provide improved stability and reduced subsidence, based on increased vertebral body contact area with an implant expanded in place to the desired height and width.
