Patent ID: 7182744

Claim:
A method for treating an aneurysm comprising: drawing a portion of blood from a patient; centrifuging said portion of blood to obtain a platelet-rich serum fraction; adding recombinant TGF-beta protein to said platelet-rich serum fraction; adding collagen to said platelet-rich serum fraction; adding contrast to said platelet-rich serum fraction; adding a gelling agent to said platelet-rich serum fraction, thereby creating an irritant serum; dispensing said irritant serum, as a fluid, from a micro-catheter into said aneurysm to cover at least a portion of said original aneurysm surface area with said irritant serum wherein said irritant serum covering said portion of said original aneurysm surface area is in contact with and remains in contact with said portion of said original aneurysm surface area; and said irritant serum remains in contact with said portion of said original aneurysm surface area and, said irritant serum gels on said original aneurysm inner surface area and said TGF-beta protein causes patient fibroblasts to exert a contractile force on said collagen causing a contractile force to be exerted on said original aneurysm surface area such that said original aneurysm surface area contracts to a contracted aneurysm surface area, smaller than said original aneurysm surface area, said contracted aneurysm surface area enclosing a contracted aneurysm volume that is smaller than said original aneurysm volume.
