The inner surface of the graft includes a coating of the substantially water-soluble material thereon. The outer surface includes a coating of the substantially water-insoluble sealant disposed thereon. The tubular wall having the coating of the substantially water-insoluble sealant is, after curing thereof, substantially impermeable to liquid.
