Spinal interbody devices with density gradients and associated methods
An interbody device configured for insertion between adjacent vertebrae includes a body comprising and exterior surface and an interior surface defining a cavity. The body comprises a visualization window extending between the exterior surface and the interior surface, where the visualization window comprises a lattice of radiopaque structures. A density of the lattice in a central region of the visualization window is less than in the density of the lattice in an outer region of the visualization window such that the visualization window is radiolucent through the central region.
POROUS SPINAL IMPLANT
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.
Intervertebral implant
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.
Systems and methods for spinal fusion
A system and method for spinal fusion comprising a spinal fusion implant of non-bone construction releasably coupled to an insertion instrument dimensioned to introduce the spinal fusion implant into any of a variety of spinal target sites, in particular into the thoracic region of the spine.
MATING INSERTER AND CANNULA FOR FUSING A SACROILIAC JOINT
An instrument set for installing a fusion implant into the sacroiliac joint. The apparatus comprises a working channel having an alignment means, an implant inserter having an inserter keying means for mating with the alignment means when the implant inserter is inserted into the working channel. The implant inserter has an insertion end with a pair of tines for releasably receiving a joint fusion implant.
Standalone anterior cervical interbody spacer
A standalone anterior cervical interbody spacer (ACIF) that includes a spacer body and plate rigidly couple via flexible pins.
Standalone anterior lumber interbody spacer
Disclosed is a standalone anterior lumbar interbody spacer that includes a lumbar spacer body and lumbar plate with a unique locking system to rigidly couple the spacer body and plate via a spring loaded lock tab.
Decorticating device for fusing a sacroiliac joint
A decorticating device for preparing a sacroiliac joint (“SI Joint”) to receive a graft implant. The decorticating device comprises an abrading head having abrading surfaces on a first pair of opposing sides, the abrading surfaces configured for decorticating the cortical bone of the SI Joint. The abrading head further comprises a second pair of opposing sides, each side of the second pair of opposing sides comprising a curved distal portion having a curved cutting edge.
Expandable inter-body device, system and method
Expandable spinal implants, systems and methods are disclosed. An expandable spinal implant may include a first endplate, a second endplate, and a moving mechanism that is operably coupled to the first and second endplates. The moving mechanism may include a wedge, a first sliding frame and a second sliding frame disposed on opposite sides of the wedge, a screw guide housing a rotatable first set screw and a rotatable second set screw opposite the first set screw. The first set screw may be operably coupled to the second sliding frame and the second set screw may be operably coupled to the wedge. The moving mechanism may operably adjust a spacing between the first and second endplates upon simultaneous rotation of the first and second set screws and operably adjust an angle of inclination between the first and second endplates upon translating the first set screw or second set screw.
VERTEBRAL BODY REPLACEMENT
The present invention involves a system and methods for assembling and implanting a vertebral body implant. The vertebral body implant includes, but is not necessarily limited to, an expandable core body and endplates that can be attached at both ends. End plates of various shapes, sizes and angles are attachable to the expandable core in a plurality of positions so that a suitable vertebral body implant can be implanted between vertebrae from an anterior, anterior-lateral, lateral, posterior or posterior-lateral approach.
