Abstract
A medical textile product includes a textile substrate having opposed first and second surfaces with the textile substrate including a textile construction of one or more yarns. The second surface includes a coating of a substantially water-insoluble, non-porous elastomeric sealant. The one or more yarns at the first surface are pre-treated with a removable composition, such that the water-insoluble elastomeric sealant encapsulates a portion of fibers of the one or more yarns at the second surface of the textile substrate. The textile substrate is substantially impermeable to fluid. The first surface is substantially free of the substantially water-insoluble elastomeric sealant. The textile substrate may be a non-tubular substrate, such as a planar sheet, a shaped sheet, and a tape, or a tubular substrate, such as a cylindrical conduit, a tubular conduit, a Y-shaped, a T-shaped conduit, a multi-channel conduit, and a bulbous shaped conduit.
