1. A vascular system, the vascular system comprising:
a vascular prosthesis comprising:
a textile tubular wall having a portion disposed between a first open end and an opposed second open end and having an inner surface and an opposed outer surface, the textile tubular wall comprising a textile construction of one or more yarns;
wherein the outer surface comprises a coating of a substantially water-insoluble, non-porous elastomeric sealant, disposed thereon;
wherein the one or more yarns are pre-treated with a removable composition, which removable composition is substantially removed prior to implantation, such that the water-insoluble elastomeric sealant encapsulates a portion of outer fibers of the one or more yarns at the outer surface of the textile tubular wall;
wherein the textile tubular wall is substantially impermeable to fluid; and
wherein the inner surface is at least 70% free of the substantially water-insoluble elastomeric sealant.
