Abstract
A composite medical device includes a knitted structure having a single layer of yarns to define a single layered wall, where the yarns are interlaced into stitches in a knit pattern capable of resilient longitudinal elongation and resilient radial contraction of the knit from a quiescent state to an elongated state, and a layer of ePTFE securably attached to the knitted structure. The knit pattern is a warp knitted pattern of yarns forming a textile layer having an interior surface and an exterior surface, where interior yarns form the interior surface and form loops in the longitudinal direction of said knitted structure, and exterior yarns form the exterior surface and are diagonally shifted over two or more of the interior yarns in an alternating pattern along a width of the knitted structure before engaging an the interior yarn.
