  • Patent number: 11813168
    Abstract: Embodiments of an artificial meniscus are disclosed herein. An artificial meniscus includes at least one circumferential fiber bundle and the at least one non-circumferential fiber bundle embedded in a polymer material. The non-circumferential fiber bundles are fully encapsulated within the polymer material, and the circumferential fiber bundles extend out of anterior and posterior horns of the artificial meniscus to terminate in ends that are configured for fixation to bone. Methods of making and implanting artificial menisci are also disclosed herein. The methods of making include, but are not limited to, stepwise molding, layering, and curing of polymer material around the circumferential and non-circumferential fiber bundles. The methods of implanting include threading ends of the circumferential fiber bundles through first and second bone tunnels, then immobilizing the ends of the circumferential fiber bundles with respect to the bone of the subject.

In one aspect, the anti-migration feature is an enlarged anterior structure or a posterior meniscus remnant engaging channel while in another aspect, the anti-migration feature includes a tethering member. Still further, removable radiopaque features are provided to enhance trialing of the implant prior to final implantation within the joint.

  • Patent number: 10085848
    Abstract: A dynamic intervertebral spacer includes a ring which is split on an anterior portion. A posterior portion of the ring acts as a torsion spring. After implantation, the ring is able to act as a spring between superior and inferior vertebral bodies, thus allowing dynamic bone growth in fusion procedures.

  • Patent number: 10045852
    Abstract: Methods of selecting and implanting prosthetic devices for use as a replacement meniscus are disclosed. The selection methods include a pre-implantation selection method and a during-implantation selection method. The pre-implantation selection method includes a direct geometrical matching process, a correlation parameters-based matching process, and a finite element-based matching process. The implant identified by the pre-implantation selection method is then confirmed to be a suitable implant in the during-implantation selection method. In some instances, the during-implantation selection method includes monitoring loads and/or pressures applied to the prosthetic device and/or the adjacent anatomy. In some instances, the loads and/or pressures are monitored by a trial prosthetic device comprising one or more sensors. Methods of implanting meniscus prosthetic devices are also disclosed.

  • Patent number: 10045851
    Abstract: This disclosure is directed to restoring joints by deploying a resilient interpositional arthroplasty implant. Such implants function to pad cartilage defects, cushion, and replace or restore the articular surface, which may preserve joint integrity, reduce pain and improve function. The implant may endure variable joint compressive and shear forces and cyclic loads. The implant may repair, reconstruct, and regenerate joint anatomy, and thereby improve upon joint replacement alternatives. The walls of this invention may capture, distribute and hold living cells until aggregation and hyaline cartilage regrowth occurs. The implant may be deployed into debrided joint spaces, molding and conforming to surrounding structures with sufficient stability so as to enable immediate limb use after outpatient surgery. Appendages of the implant may repair or reconstruct tendons or ligaments, and menisci by interpositional inflatable or compliant polymer arthroplasties that promote anatomic joint motion.

  • Patent number: 10034755
    Abstract: An implant device used to replace and restore the function of the knee meniscus in a human. The compliant, yet resilient device is comprised of a biocompatible, non-degradable three-dimensional body comprised of at least a central body, a second structure, a third structure, and a coating. The device is concentrically aligned wherein the second structure is adjoined to the central body wherein the third structure is adjoined on the central body opposite of the second structure. The third structure further features a first and a second pulling element which is coupled to the central body and forms the outer periphery and major circumference of the device. The device is comprised of multiple components which provide tensile strength, compressive resilience, and attachment mechanisms for replacing the meniscus. Each structure is comprised of multiple surfaces which are further reinforced, separated, and connected by an individual plurality of vertical elements.

  • Patent number: 10034778
    Abstract: A workstation having a pair of posts on either side of a clamping plate where a donor bone may be placed on sequentially cut in three separate cutting paths. Cutting gates are attached to the posts and used to provide cutting paths that can be precisely oriented with respect to the meniscus of the donor bone part using visual alignment without any manual measurements. The graft is affixed to a machining clamp and shaved to appropriately shape the sides and form a radius on the bottom of the graft. A tibia is then prepared by using a drill guide to form a pilot hole and then to drill out a large hole for the graft. The drilled hole is expanded and shaped using a rod guide and chisel and then a rasp. The shaped graft may then be implanted into the shaped hole and sutured in place.
