Patent ID: 7166124

Claim:
A method for manufacturing a sutureless bioprosthetic stent graft suitable for physiological implantation, comprising: wrapping a sheet of biomaterial on a mandrel to form a biomaterial roll having a first end, a second end, a lumen-facing first surface, an outward-facing second surface and an at least partial overlap of the biomaterial, the biomaterial first and second surfaces consisting essentially of an optically-transmissive collagen-rich matrix suitable for cell repopulation; positioning a stent frame over the second surface of the biomaterial roll and intermediate the first and second ends of the biomaterial roll; everting the first end of the biomaterial roll over the stent frame to encase the stent frame within apposed second surfaces of the biomaterial; suturelessly bonding the biomaterial; and removing the biomaterial roll from the mandrel; wherein suturelessly bonding the biomaterial consists of photo-chemically cross-linking the collagen-rich matrix of the apposed second surfaces of the biomaterial by applying a photo-active crosslinking agent to the second surface to provide a photo-activable light absorptive surface on the optically-transmissive collagen rich matrix and irradiating at least the first end of the biomaterial roll with visible or UV light.
