Abstract
A textile graft includes a tubular wall disposed between a first open end and an opposed second open end and having an inner surface and an opposed outer surface. The tubular wall includes a textile construction of one or more filaments or yarns, the textile construction by itself being permeable to liquid. A portion of the inner surface of the tubular wall includes a coating of a substantially water-soluble material thereon. The outer surface includes a coating of a substantially water-insoluble elastomeric sealant disposed thereon. The tubular wall having the coating of the substantially water-insoluble elastomeric sealant is, after curing thereof, substantially impermeable to liquid.
