Claim 7
Independent Claim
73 words
A method of making a surgical sponge, comprising the steps of: passing a first layer of a mass of fibers; passing a second layer of a mass of fibers adjacent the first layer; placing an elongated radiopaque element intermediate the first and second layers; and fluidentangling the fibers of the first and second layers together and about said element to form a sheet of entangled fibers with the element embedded in the sheet.
