Disclosed are products and methods for treating soft tissue injuries. The provided methods include the production of processed or cryopreserved microvascular tissue. Also provided are products and methods of using processed or cryopreserved microvascular tissue for the treatment of soft tissue injuries.

A composition that includes (a) a prepolymer having at least one free isocyanate group that is capable of bonding to tissue and that cures in vivo upon exposure to water to form a polymer having a compressive modulus between 1.9 and 14.4 MPa and a tensile modulus between 5.0 and 30, and (b) an oil that is miscible in the prepolymer, the oil being selected from the group consisting of silicone oils, mineral oil, vegetable oils, and combinations thereof. The composition retains its integrity when delivered in an aqueous medium.

The current invention relates to a method for the preparation of a gel-forming composition for parenteral administration, said method comprises the steps of admixing a mixture of mammalian derived plasma and hyaluronic acid or a salt or ester thereof with a source of calcium, and wherein said calcium source is added to said mixture such that the calcium concentration is between 0.2 and 1.4 mg/ml. The invention also relates to a composition obtained by the method.

In a connective-tissue body according to an embodiment of the present disclosure, comprising a biological tissue including collagen, a fine surface layer formed more finely than the inside thereof is provided on the surface of the connective-tissue body.

Provided herein is an electrodeposition apparatus for producing long polymeric threads, yarns, or ropes. A method of preparing long polymeric threads, yarns or ropes also is provided.

Disclosed are products and methods for treating soft tissue injuries. The provided methods include the production of processed or cryopreserved microvascular tissue. Also provided are products and methods of using processed or cryopreserved microvascular tissue for the treatment of soft tissue injuries.

Felt material (1) comprising a multitude of fibers (2) for use in a method of repairing or augmenting human or animal soft tissues (3), wherein the felt material (1) is in the form of a matting or felted patch (9) comprising a first surface (5) and oppositely arranged a second surface (6) for contacting a surface of soft tissue (3), and wherein some of the fibers (2) of the felted patch (9) are pushed or pulled through the second surface (6) into the soft tissue (3) by means of a needle (10) producing a connection between the felt material (1) and the soft tissue (3). Further, a set of instruments is provided which comprises a needle (10), a stitching device (30) and a clamping device (20) comprising a first jaw (21a) which is frame-like configured permitting the tip portion of the needle (10) to penetrate the first jaw (21a) and a second jaw (21b) with a cavity (29) configured to receive the tip portion of the needle (10).

Described herein is a device for an intervention of reconstruction of a cruciate ligament that includes a penetrator defining a first passage lumen, and sleeve member coupled to the penetrator and defining a second passage lumen that is in communication with the first passage lumen. The penetrator is configured for being introduced into a tibial plate and for receiving a replacement cruciate ligament through the first passage lumen. The sleeve member is configured for receiving the replacement cruciate ligament through the second passage lumen.

Disclosed herein are various bioreactor devices that mimic the mammalian joint. The bioreactor device can include a series of bioreactor chambers that contain different components of the joint, such as bone, cartilage, synovium, nerve and ligament. At least two different nutrient fluid circulation systems connect subsets of the bioreactor chambers to differentially supply nutrient fluids at concentrations optimized for the tissue that the fluid nourishes. For example, relatively hypoxic fluid can be supplied to synovium and cartilage to mimic oxygenation in the joint compartment, but normoxic fluid can be supplied to the bone and other components that have an arterial supply that provides higher oxygen concentrations. One or more or all of the bioreactor chambers can be supplied with separate inlets through which perturbation agents (such as drugs or other agents) can be introduced to model the effect of the perturbations on different components of the system. In some cases, the system can include a well plate having a plurality of wells and a bioreactor situated in each well of the well plate.

Disclosed herein are embodiments of orthopedic devices. In several embodiments, orthopedic device comprises a biocompatible covering. In several embodiments the biocompatible covering is a collagen-based material. In several embodiments, the collagen-based material is crosslinked using an epoxide-based crosslinking agent (e.g., a diepoxide, triepoxide, etc.). In several embodiments, after a precursor crosslinked collagen-based material is prepared (e.g., by subjecting it to crosslinking conditions), residual crosslinking agent in the precursor material is quenched. In several embodiments, it has been surprisingly found that, by subjecting the precursor crosslinked collagen based material to a quenching reaction (to provide the crosslinked collagen-based material), improved properties are obtained (e.g., lower toxicity lower cytotoxicity, etc.). In several embodiments, the crosslinked collagen-based material is fabricated into an orthopedic device or used to prepare an orthopedic device (e.g., implant).
