Abstract
A substantially fluid impermeable textile graft may be produced by selective application of a substantially water-soluble material or masking agent, and optionally selective removal of excess substantially water-soluble material, followed by the application of a substantially water-insoluble sealant. 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. The substantially water-soluble material is removed from the graft after the application of the substantially water-insoluble sealant.
