Abstract
A warp-knitted fabric has pile loops on both faces thereof. The loops on both faces are continuous with each other so that when the fabric is used as a prosthesis, growth of tissue from one face to the other is facilitated. This feature is particularly significant when the fabric is fashioned into tubular form, whether straight or bifurcated. The structure of the fabric is such that a desired degree of rigidity is obtained with a thinner fabric than has hitherto been the case.
Claims19
A warp-knitted prosthesis, comprising a trellis, pile velour exterior to said trellis and pile velour interior to said trellis, said pile velour being in the form of loops protruding from said trellis, said trellis consisting of a flat thread of synthetic fiber warp-knitted in closed stitch, and said pile velour consisting of a texturized thread of synthetic fiber in open stitch passing through said trellis to form loops interior to and exterior to said trellis, said interior and exterior loops being continuous with each other for facilitating ingrowth of tissue from the exterior of said prosthesis to the interior thereof, the combination of a trellis warp-knitted of flat thread in closed stitch and a velour of texturized thread in open stitch providing minimum porosity, appropriate rigidity for functioning as a prosthesis and extremely fine hand.
