Abstract
A method of manufacturing a tubular graft may include the steps of: providing a textile including a tubular wall disposed between a first open end and an opposed second open end, an inner surface and an opposed outer surface defining an interior wall portion therein between, the tubular wall including a textile construction of one or more filaments or yarns, the textile construction by itself being permeable to liquid; applying a substantially water-soluble material to at least a portion of the tubular wall; and applying a substantially water-insoluble sealant to at least a part of the outer surface of the tubular wall, the substantially water-insoluble sealant being configured to mitigate movement of fluid through the wall of the conduit; where the water-soluble material is configured to mitigate penetration of the sealant to the inner surface of the conduit.
