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.

APPARATUS FOR TRANSFORMING TEETH INTO BONE GRAFT MATERIAL
20210236303 · 2021-08-05 · ·

An apparatus for transforming teeth into bone material, which is suitable to treat the teeth by immersion in liquids and includes a reactor device including a contactor, a reaction chamber, an ejection chamber, a cartridge including a plurality of containers for the processing and washing liquids, separated liquid-tight from each other, a fragmentation device suitable to fragment teeth, a guide suitable to detachably connect the cartridge and the fragmentation device to the apparatus, and a movement device suitable to detachably connect at least partially the reactor device and allow it to sequentially withdraw the teeth from the fragmentation device and the liquids from the cartridge.

SYSTEM AND METHOD OF BONE PROCESSING

A system and method of processing bone is disclosed. A tissue separator is utilized to separate tissue comprising at least one of muscle, periosteum and connective tissue from bone in a safe, sterile and efficient manner. In one aspect, the particle reducer can include an impeller positioned with respect to a cutting surface on a drum. At least one of the impeller and the drum is rotated by a power source such that harvested tissue frictionally engages the cutting surface. In another aspect, a source of pressurized fluid can be directed at tissue to separate bone from non-bone tissue.

Method Of Converting Bone Stock Into Bone Chips

A mill head for replaceable attachment to a base so as to collectively form a bone mill. The mill head includes shell with: a first opening in which bone stock is introduced into the head; and a second opening through which the bone chips are discharged. A cutting device is mounted in the shell to both rotate and move laterally. Attached to the cutting device are coupling features for engaging a drive spindle able to rotate the cutting device. Also attached to the housing is an alignment feature. The alignment feature engages a complementary alignment feature associated with the drive spindle so as a result of the engagement of the alignment features, the cutting device moves within the shell so that the cutting device coupling features are positioned to engage the drive spindle.

Bone Cleaning Assembly

A cleaning module for cleaning bone stock used in surgical procedures. The cleaning module includes a shell. The shell defines a void space to receive the bone stock. A cutter is rotating mounted in the void space. A shaving tube, also able to rotate, is coaxially disposed about the cutter. The cutter and shaving tube have complementary edges. A drive assembly rotates the cutter and shaving tube at different speeds, at different times or in different directions relative to the cutter. As a result of the rotation of the cutter and shaving tube soft tissue adhering to the bone stock is cut away from the bone stock by the relative rotating of the cutting edges of the cutter and shaving tube.

Bone Cleaner That Removes Soft Tissue By Pressing Bone Stock Against A Cleaning Element And Clearing The Bone Stock From The Cleaning Element

A bone cleaning assembly (102, 602) with cleaning elements (690, 724, 1230, 1264) that remove soft tissue from bone stock. The module also includes a clearing element (778) that is periodically urged against the cleaning elements to remove bone stock trapped by the cleaning elements from the cleaning elements.

BONE MATERIAL HYDRATION DEVICES AND METHODS

A device for hydrating particulate bone material is provided. The device comprises a tubular member having an interior surface and an exterior surface. The interior surface is configured to receive the particulate bone material and a hydration fluid. The exterior surface has a plurality of pores configured to allow the hydration fluid to flow into the interior surface of the tubular member and hydrate the particulate bone material. The plurality of pores are smaller in size than the particulate bone material. Methods of dispensing particulate the bone material are also provided.
