Patent number: 12208001Abstract: A system and a method of preventing or reducing stenosis in a subject is provided. The method includes implanting a passivated graft comprising vein into an artery. The implanting of the graft replaces and/or bypasses a diseased segment of the artery. The passivated graft including vein is prepared by exposing the exterior surface of the passivated graft comprising vein to a tissue structure stabilizing agent (“TSSA”) under conditions, including irradiation with light, sufficient to promote cross-linking of proteins within the vein.Type: GrantFiled: April 28, 2022Date of Patent: January 28, 2025Assignee: The General Hospital CorporationInventors: William G.
