Low profile, high stretch, low dilation knit prosthetic device

An implantable tubular graft comprising:

• a tubular knitted tubular graft comprising a layer of yarns to define a wall, said yarns being interlaced into stitches in a knit pattern capable of resilient longitudinal elongation and resilient radial contraction of said graft from a quiescent state to an elongated;
• wherein said knit pattern is a warp knitted pattern of yarns forming a textile layer having an interior surface and an exterior surface, wherein interior yarns comprise the interior surface and form loops in the longitudinal direction of said graft, and exterior yarns comprise the exterior surface and are diagonally shifted over two or more of the interior yarns in an alternating pattern along a width of said graft before engaging an the interior yarn.

An implantable device comprising:

• a textile structure having a single layer of yarns to define a tubular wall having a first surface and a second opposed surface, wherein a first yarn comprises the first surface and forms loops in the longitudinal direction of said structure, and a second yarn comprises the second surface and is diagonally shifted over two or more of the first yarns in an alternating pattern along a width of said structure before engaging the first yarn to permit longitudinal expansion of at least about 50 percent by length of the length of said structure.

An implantable device comprising:

• a textile structure having a single layer of yarns interlaced into stitches in a knit pattern capable of resilient longitudinal expansion from a quiescent state and having at least about 400 stitches per square centimeter and further having no more than about 1,000 stitches per square centimeter to provide compliancy for the structure;
• wherein said knit pattern is a warp knitted pattern of yarns forming a textile layer having a first surface and a second opposed surface, wherein a first yarn comprises the first surface and forms loops in the longitudinal direction of said fabric, and a second yarn comprises the second surface and is diagonally shifted over two or more of the first yarns in an alternating pattern along a width of said fabric before engaging the first yarn, and further wherein said textile structure is a tubular graft structure or a medical fabric structure.

A knitted medical fabric comprising:

• a knitted structure having a single layer of yarns interlaced into stitches in a knit pattern capable of resilient longitudinal expansion from a quiescent state and having at least about 400 stitches per square centimeter and further having no more than about 1,000 stitches per square centimeter to provide compliancy for the structure;
• wherein said knit pattern is a warp knitted pattern of yarns forming a textile layer having a first surface and a second opposed surface, wherein a first yarn comprises the first surface and forms loops in the longitudinal direction of said fabric, and a second yarn comprises the second surface and is diagonally shifted over two or more of the first yarns in an alternating pattern along a width of said fabric before engaging a the first yarn.
