CRAFTING OF CARTILAGE

A shaped cartilage matrix isolated from a human or animal where the cartilage has been crafted to facilitate disinfection, cleaning, devitalization, recellularization, and/or integration after implantation. Also, a process for repairing a cartilage defect with the cartilage matrix. The matrix is in the form of an osteochondral plug including a cartilage cap ad subchondral bone, wherein one or more gaps, slats, bores, or channels extend through the tidemark at the interface between the cartilage cap and the subchondral bone.

Crafting of cartilage

A shaped cartilage matrix isolated from a human or animal where the cartilage has been crafted to facilitate disinfection, cleaning, devitalization, recellularization, and/or integration after implantation. Also, a process for repairing a cartilage defect with the cartilage matrix. The matrix is in the form of an osteochondral plug including a cartilage cap ad subchondral bone, wherein one or more gaps, slats, bores, or channels extend through the tidemark at the interface between the cartilage cap and the subchondral bone.

IMPLANTATION OF CARTILAGE

The invention is directed towards a process for implanting a cartilage graft into a cartilage defect and sealing the implanted cartilage graft with recipient tissue by creating a first bore down to the bone portion of the cartilage defect, creating a second shaped bore that is concentric to and on top of the first bore to match the shape and size of the cartilage graft, treating the first bore and the second shaped bore at the defect site with a bonding agent, treating the circumferential area of the cartilage graft with a bonding agent, inserting the cartilage graft into the defect site and wherein the superficial surface of the cartilage graft is at the same height as the surrounding cartilage surface. The first and second bonding agents may be activated by applying a stimulation agent to induce sealing, integration, and restoration of the hydrodynamic environments of the recipient tissue. The invention is also directed towards a process for repairing a cartilage defect and implanting a cartilage graft into a human or animal by crafting a cartilage matrix into individual grafts, cleaning and disinfecting the cartilage graft, applying a pretreatment solution to the cartilage graft, removing cellular debris using an extracting solution to produce a devitalized cartilage graft, implanting the cartilage graft into the cartilage defect with or without an insertion device, and sealing the implanted cartilage graft with recipient tissue. The devitalized cartilage graft is optionally recellularized in vitro, in vivo, or in situ with viable cells to render the tissue vital before or after the implantation. The devitalized cartilage graft is also optionally stored between the removing cellular debris and the recellularizing steps. The invention is further directed toward a repaired cartilage defect.

SPINAL IMPLANT AND ASSEMBLY
20210290406 · 2021-09-23 · ·

An implant assembly is shown and described. The implant has at least one or a plurality of elastic, resilient or flexible arms that each have a detent adapted to retain at least one screw in a locked position in the implant. At least one of the arms has a portion that extends into a screw aperture such that an arm axis is generally parallel to the axis of the screw after the screw is received in the implant. In another embodiment, means or a system for locking the multi-component implant members together is shown.

Medical implant for fixation and integration with hard tissue

The invention relates to medical implants, including spinal implants and bone grafts, for fixation and integration with hard tissue. The bone medical implants include at least one rotational fixation mechanism that further includes or is attached to one or more sharp protrusions configured to penetrate and become lodged into hard tissue to provide support and positional stability. Such support is useful to ensure that the spinal bone graft may be used without additional stabilizing or anchoring structures, such as supporting plates or screws.

SPINAL INTERBODY WITH COMPRESSIVE FUSION FEATURES

A glenoid implant system may include a main body formed of a polymer, a base, and an anchor formed of metal. The main body may define an articulating surface and an opposite bone-contacting surface. The base may be formed in the bone-contacting surface of the main body, the base including a hole formed therein. The anchor may have a main section and a threaded post extending from the main section. The anchor may include a plurality of ribs extending in a longitudinal direction of the main section, the plurality of ribs being spaced apart from one another in a circumferential direction of the main section. The anchor may further include a plurality of wedges disposed on a base of the anchor, the plurality of wedges adapted to contact the base formed in the bone-contacting surface of the main body when the threaded post is received within the threaded hole.
