Described are expanded collagenous materials and methods for their preparation and use. Certain expanded collagenous materials can be prepared by treating a first collagenous material with an alkaline substance under conditions effective to expand the first collagenous material, and recovering the expanded material. Expanded materials can exhibit beneficial persistence and tissue generation characteristics when implanted, and can be used in the formation of highly porous medical implant bodies which can be compressed to fractions of their original volume and will thereafter substantially recover their original volume.

Physically modified extracellular matrix materials and uses thereof

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 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 with increased resistance to enzymatic degradation

Described in certain aspects are composite extracellular matrix material products including expanded collagenous materials in combination with non-expanded collagenous materials. Methods for their preparation and use are also disclosed. Certain expanded collagenous materials can be prepared by treating a first collagenous material with an alkaline substance under conditions effective to expand the first collagenous material, and recovering the expanded material. Expanded materials can exhibit beneficial persistence and tissue generation characteristics when implanted, and can be used in the formation of highly porous medical implant bodies which can be compressed to fractions of their original volume and will thereafter substantially recover their original volume.

Composite extracellular matrix materials and medical products formed therefrom

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.
