Described are packaged, sterile medical graft products containing controlled levels of a growth factor such as Fibroblast Growth Factor-2 (FGF-2). Also described are methods of manufacturing medical graft products wherein processing, including sterilization, is controlled and monitored to provide medical graft products having modulated, known levels of a extracellular matrix factor, such as a growth factor, e.g. FGF-2. Preferred graft materials are extracellular matrix materials isolated from human or animal donors, particularly submucosa-containing extracellular matrix materials. Further described are ECM compositions that are or are useful for preparing gels, and related methods for preparation and use.

Graft materials containing bioactive substances, and methods for their manufacture

Described are medical grafting materials that include a base substrate material and an adherent fibrous mass of extracellular matrix components received upon the substrate material. Also described are methods of preparing and using such materials.

Medical graft materials with adherent extracellular matrix fibrous mass

Described are devices, methods, and systems for grafting tissues or organs that are exposed to bacterial or mammalian enzymes that degrade collagenous materials. Illustrative medical grafts are processed by contacting a collagenous extracellular matrix (ECM) material with a mono-carboxylic acid having from four to about twelve carbon atoms, or mixtures of two or more such acids.

Graft materials containing ECM components, and methods for their manufacture

Described are packaged, sterile medical graft products containing controlled levels of a growth factor such as Fibrob-last Growth Factor-2 (FGF-2). Also described are methods of manufacturing medical graft products wherein processing, including sterilization, is controlled and monitored to provide medical graft products having modulated, known levels of a extracellular matrix factor, such as a growth factor, e.g. FGF-2. Preferred graft materials are extracellular matrix materials isolated from human or animal donors, particularly submucosa containing extracellular matrix materials. Further described are ECM compositions that are or are useful for preparing gels, and related methods for preparation and use.

Described are methods and systems for drying remodelable materials, such that selective regions of the remodelable materials have differing properties. Also described are medical graft products having selective regions of differing material properties. Advantageous remodelable materials include collagenous extracellular matrix material, such as small intestine submucosa.

Medical graft products with differing regions and methods and systems for producing the same

The invention provides tissue graft compositions comprising collagen-based extracellular matrices derived from renal capsules of warm-blooded vertebrates. The invention further provides a process of harvesting and purifying a renal capsule to provide an extracellular matrix material having beneficial use as a tissue graft and/or cell growth material.

Graft prosthesis devices containing renal capsule collagen

A method for preparing a bioactive extract from warm-blooded vertebrate submucosal tissue is described. The submucosal tissue is extracted using an aqueous solution of extraction excipients, and the extracted bioactive components are then separated from the extraction excipients to provide an isolated extract enriched in bioactive components. The isolated extract is useful, inter alia, as additive for cell growth media to promote cell growth and proliferation in vitro.
