Claims Analysis
Total Claims: 4
Claim 1
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 entangling the fibers of the first and second layers together and about said element to form a sheet of entangled fibers with the element embedded inside the sheet.
Claim 2
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 entangling the fibers of the first and second layers together and about said element to form a sheet of entangled fibers with the element embedded inside the sheet.
Claim 3
Dependent Claim
56 words
A surgical sponge including an integral X-ray detectable element, said sponge comprising a fibrous, nonwoven fabric consisting essentially of entangled fibers arranged in an interconnecting relationship, in the fabric, and at least one X-ray detectable element positioned interiorly of said fibrous nonwoven fabric, the fibers of said nonwoven fabric being intertwined about said X-ray detectable element.
Claim 4
Dependent Claim
