A method of making infused non-demineralized cartilage particles employs the following steps: cutting or shaving cartilage tissue into cartilage particles, washing the particles, and infusing the particles with a supernatant of biologic material or a polyampholyte cryoprotectant or a combination of both to create infused particles.

A cell or tissue embedding device having an aqueous gel serving as an immunoisolation layer, the aqueous gel containing, as components thereof, a denatured polyvinyl alcohol resin having an activated carbonyl group and a crosslinking agent is highly capable of supplying a physiologically active substance.

A tissue graft for soft tissue repair or reconstruction comprising a sheet of a biopolymer-based matrix having a plurality of small perforations and a plurality of large perforations. The small perforations are sized to facilitate clotting and granulation tissue development within the perforations which, in turn, facilitates revascularization and cell repopulation in the patient. The large perforations are sized to reduce the occurrence of clotting and granulation tissue development within the perforations so that extravascular tissue fluids accumulating at the implant site can drain through the tissue graft. The large perforations enhance mammal tissue anchoring by permitting mammal tissue to compress into the perforations increasing mammal tissue contact area.

Disclosed herein are compositions and methods to decellularize an isolated organ or portion thereof. Also disclosed herein are compositions and methods for treatment of disease utilizing a decellularized or recellularized organ. Also disclosed herein are methods of improving decellularization and/or recellularization of an isolated organ or portion thereof.

A method is provided for preparing an ECM material, including an ECM gel, from regenerative or regenerating tissue. ECM material prepared from regenerative or regenerating materials also is provided.

Systems, methods, and devices include techniques for generating and using a demineralized bone matrix (DBM)-gelatin matrix allograft material. The DBM-gelatin material can be used to form an implant (e.g., for sternal closure operations) and/or a gel (e.g., for wound/fracture treatment). A method for forming the implant or bone graft can include forming the DBM from an initial bone material; and mixing, in a solution, the DBM with a gelatin carrier to form a DBM-gelatin solution. The gelatin carrier can include an animal-based collagen, such as a porcine-based collagen or a bovine-based collagen. Additionally, the method of forming the bone graft can include performing a crosslinking reaction with the DBM-gelatin solution. The implant can be packaged in a sterile hydration container prior to use.

A biodegradable mesh implant for use in soft tissue repair, in particular surgical hernia, chronic wound healing or fistula repair, within the body of a patient is disclosed. The mesh implant includes a porous, hydrophilic biodegradable polymeric carrier mesh and fibroblasts on or within the polymeric carrier mesh. The carrier mesh includes a sponge-like structure with interconnected pores of different sizes, has a water contact angle of less than 75° and is made of at least a first polymer comprising polylactic acid as a main component.

A cell-free combination for use in the controlled, especially decelerated or retarded, release of active ingredient and/or in the production of a formulation in hydrogel form, especially depot formulation in hydrogel form, and/or as a formulation in hydrogel form, especially depot formulation in hydrogel form, and/or for the coating of a medical product, especially implant, preferably with a formulation in hydrogel form, especially depot formulation in hydrogel form, wherein the cell-free combination comprises a first component and a second component, the first component comprising crosslinkable albumin and the second component comprising a crosslinking agent for the albumin. Additionally, a hydrogel-forming material or hydrogel, to a kit or multicomponent system, to a medical product or a pharmaceutical formulation, to a discharge device, and to uses of the cell-free combination and of the hydrogel-forming material or hydrogel.

The present invention provides a method of penis enlargement. The method comprises administering to a site of penis of a subject a graft enriched with adipose derived regenerative cells.

In one aspect, methods are described herein employing particle compositions operable to form composite membrane for inhibition of post-surgical adhesions. Briefly, a method of treating a surgical site comprises contacting the surgical site with a particle formulation comprising targeting particles and scaffolding particles. The targeting particles and scaffolding particles are crosslinked to provide a composite membrane at the surgical site, wherein formation of post-surgical adhesions are inhibited by the composite membrane.
