A method and apparatus is provided for creating a modified tissue graft, wherein an anatomical site at which the modified tissue graft is to be placed is identified, desired characteristics for the modified tissue graft are identified based at least upon the anatomical site, one or more types of graft modifications and regions of the tissue graft to be modified are identified to achieve the desired characteristics; and at least a first area and a second area of the exterior surface of the tissue graft are modified by compressing, cutting and/or removing one or more portions thereof to create first designed surface features which cause the tissue graft to have first characteristics in the first area and second designed surface features which cause the tissue graft to have second characteristics in the second area.

A process and system provides for atraumatic preparation of morselized Tissue Particles (TP)s, such as Full Thickness Skin Graft Particles (FTSGPs), cartilage particles and other organ tissue particles, in a liquid medium. The resultant tissue product may be a suspension of Tissue Particles in an aqueous solution and containing highly viable cells and may be rapidly prepared at bedside or in the operating room and conveniently delivered to a patient through a syringe or similar applicator. The morselized Tissues Particles may be used for surgical applications including wound healing, cosmetic surgery, and orthopedic cartilage repairs.

Aspects of the disclosure relate methods and a synthetic cell delivery device for treating trauma present relative to the inner surface of a hollow organ such as an esophagus.

Provided herein are tissue grafts, and in particular human placenta-derived tissue grafts and methods and articles for the manufacture and use thereof.

This disclosure describes decellularized, biologically-engineered tubular grafts and methods of making and using such decellularized, biologically-engineered tubular grafts.

A composition and methods of making or use thereof include a plurality of fibers forming a shape for augmenting fixation of a bone screw, or the plurality of fibers form a shape having a peg portion and a sheet portion to augment tendon to bone repair. The physical presence of the plurality of fibers provides initial fixation, while the use of an osteoinductive material provides long term enhancement of bone formation around the site of the bone screw or the tendon to bone repair.

Disclosed is a method for controlling the Young’s modulus of a three-dimensional tissue containing cells and an extracellular matrix by adjusting the average diameter of an extracellular matrix in production of the three-dimensional tissue.

A mechanoactive material includes a composite textile that includes a textile substrate formed from a plurality of fibers assembled in a fiber assembly pattern and a material deposited via an additive manufacturing technique onto and/or between the fibers of the textile substrate based on an additive manufacturing pattern. The composite textile includes at least one prestress and/or residual stress and/or exhibits a change in at least one mechanical property, material property, or structure in response to at least one endogenous and/or exogenous stimulus.

The present disclosure relates to cartilage repair compositions and methods for modifying the proteoglycan content of the compositions. Specifically, the methods relate to serum free, collagen free neocartilage made from chondrocytes that can be used for implants. Proteoglycans, such as aggrecan and sulfated glycosaminoglycan are used and the content modified using temperature changes.

Thin-film mesh for medical devices, including stent and scaffold devices, and related methods are provided. Micropatterned thin-film mesh, such as thin-film Nitinol (TFN) mesh, may be fabricated via sputter deposition on a micropatterned wafer. The thin-film mesh may include slits to be expanded into pores, and the expanded thin-film mesh used as a cover for a stent device. The stent device may include two stent modules that may be implanted at a bifurcated aneurysm such that one module passes through a medial surface of the other module. The thin-film mesh may include pores with complex, fractal, or fractal-like shapes. The thin-film mesh may be used as a scaffold for a scaffold device. The thin-film scaffold may be placed in a solution including structural protein such as fibrin, seeded with cells, and placed in the body to replace or repair tissue.
