Abstract A surgical sponge comprising, a sheet of absorbent material comprising a plurality of layers of an open mesh gauze fabric having generally parallel woven spaced warp and filling yarns. The sheet has one or more spaced generally parallel tie-in yarns interwoven between the layers in at least one direction of the sheet, with a substantial number of the yarns in one layer generally parallel to the tie-in yarns being located intermediate the corresponding yarns in another layer of the sheet to define a staggered configuration of the sheet yarns, with the tie-in yarns limiting freedom of movement of the staggered woven yarns to retain them in place, and with the sheet being folded into a multiple ply configuration.
A surgical sponge, comprising: a sheet of absorbent material comprising only two layers of an open mesh gauze fabric having generally parallel woven spaced warp and filling yarns, with a first layer in the sheet comprising totally hydrophobic yarns and defining a first outer surface of the sheet, with a second layer of the sheet comprising substantially hydrophilic yarns and defining a second opposed outer surface of the sheet, with said sheet being folded into a multiple ply configuration, and with the first layer of hydrophobic yarns solely facing outwardly from the folded sheet, wherein the sheet has one or more spaced generally parallel tie-in yarns interwoven between the layers in at least one direction of the sheet.
