Surgical barrier
First Claim
1. A woven structure for use in a surgical operation comprising an elongate, tubular knit fabric having opposite ends, means closing said ends so that said fabric will be flattened and malleable and conformable to internal body cavities, said structure including means for reducing absorption of liquids by the fabric, said fabric having a selected width and length and said means for reducing absorption of liquids comprising a thin sheet of liquid impervious material disposed within said tubular fabric, said sheet having substantially the same width and length as said fabric, means securing said sheet in place within said fabric.

Abstract
A knitted tubular fabric is made from a synthetic yarn having a low capacity for liquid absorption; the ends of the tubular fabric are stitched closely so that the fabric will lie flat; the fabric is elongated in shape compared to its width and is used to provide a barrier around the edge of a surgical site, particularly in the abdomen, to be held in place by hand or by mechanical retractors to hold back away from the site other internal organs; the interior of the tubular fabric may be provided with a thin flexible liquid impervious sheet and which is held in place by parallel stitching along the length of the fabric.
