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.
Claims7
A method for preparing a medical graft product, comprising:
- contacting an extracellular matrix material retaining growth factors or other bioactive components native to a source tissue for the extracellular matrix material with a mono-carboxylic acid having from four to twelve carbon atoms in an amount effective to increase resistance of the extracellular matrix material to degradation caused by enzymes relative to an untreated extracellular matrix material.
The method claim of 4, wherein said small intestinal submucosa is bioremodelable.
The method claim of 5, wherein said mono-carboxylic acid comprises octanoic acid.
Dependencies are inferred from the claim text.
