Abstract
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.
