An expandable spinal implant includes a distal projection extending from only one side of the implant, ending in an anterior tip, the anterior portion and anterior tip defining an elongated distal end hook, which is wider than the proximal end. The distal end hook rotates around the spinal cord, aligning the implant with a desired pathway, then inserts into place in the disc space between the vertebrae. The elongated widened distal end hook provides a TLIF approach, distributes loads, provides anterior rim engagement, and creates lordosis.

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.

A multi-chamber balloon for a nuclear implant has an elastomeric membrane defining inner and outer chambers integral with a valve body. The valve body includes a core portion and sealing membrane for sealing the inner and outer chambers. An assembly for manufacturing the multi-chamber balloon includes a balloon mandrel which may be dip coated in a silicone dispersion to create an elastomeric membrane for the inner and outer chambers integral with the valve body. The elastomeric membrane formed on the mandrel is partially inverted to form a coaxial elastomeric structure with the smaller inner chamber disposed within the larger outer chamber. The valve is incorporated into the inner and outer chambers to form a unitary structure.

A standalone anterior cervical interbody spacer (ACIF) that includes a spacer body and plate rigidly couple via flexible pins.

A spinal disc implant including a body defined by a plurality of interwoven or braided nitinol strands. The body includes a first end and a second end. The nitinol strands come together at the first end and are secured with a first fitting. The nitinol strands also come together at the second end and are secured with a second fitting. The second fitting can include a snare hook. The braided nitinol skeleton is internally assembled within the intervertebral disc. The implant is filled with liquid, gel or silicone when utilized as a motion preserving nucleus pulpous implant. The implant is filled with bone graft material when utilized as an inter-body fusion implant. An instrument and technique that provides a minimally invasive “needle based” solution to address degenerative disc disease with enhanced structural integrity of the spine compared to conventional surgical devices and techniques.

Provided herein are biomimetic osteochondral implants that are generally useful for the at least partial resurfacing of damaged cartilage within a joint. The implants are constructed to have a modular, layered structure in which the physical properties (e.g., stiffness and lubricity) or dimensions of each layer can be adjusted (e.g., by using the appropriate material and controlling the thickness thereof) based on the anatomy to be replaced. For example, the material and or thicknesses of the layers can be selected to approximate the physical properties and/or dimensions of cartilage (and, optionally, chondral and subchondral bone). Also provided herein are methods of treatment involving the use of said biomimetic osteochondral implants to repair an osteochondral defect in a joint.

Pedicle-based intradiscal fixation devices, systems, instruments, and methods thereof. A pedicle-based intradiscal implant for stabilizing an inferior vertebra and a superior vertebra may include a bendable rod configured to engage bone, a bone fastener defining a channel for receiving the bendable rod, and a locking cap for securing the bone fastener and the bendable rod. The implant may be positioned through a pedicle of an inferior vertebra and the bendable rod may be deployable into the vertebral body of the inferior vertebra, through the disc space, and into the vertebral body of the superior vertebra to stabilize the spine.

Orthopedic implants, systems, instruments, and methods. A bi-portal lumbar interbody fusion system may include an expandable interbody implant and minimally invasive pedicle-based intradiscal fixation implants. The interbody and intradiscal implants may be installed with intelligent instrumentation capable of repeatably providing precision placement of the implants. The bi-portal system may be robotically-enabled to guide the instruments and implants along desired access trajectories to the surgical area.

A spinal implant comprises an implant body extending between an anterior surface and a posterior surface and includes a first vertebral engaging surface and a second vertebral engaging surface. The implant body includes an inner surface that defines at least one cavity that is oriented to implant a fastener oblique relative to a lateral axis of a subject body and adjacent an intervertebral space of the subject body. At least one indicia is disposed with the implant body to facilitate orientation of the implant body with the subject body. Systems and methods are disclosed.

An orthopedic device for implanting between adjacent vertebrae comprising: an arcuate balloon and a hardenable material within said balloon. In some embodiments, the balloon has a footprint that substantially corresponds to a perimeter of a vertebral endplate. An inflatable device is inserted through a cannula into an intervertebral space and oriented so that, upon expansion, a natural angle between vertebrae will be at least partially restored. At least one component selected from the group consisting of a load-bearing component and an osteobiologic component is directed into the inflatable device through a fluid communication means.
