Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
53 words
A surgical sponge, comprising an absorbent fabric; and an elongated radiopaque filament integrally bonded to fibers in said fabric to prevent dislodgment of said filament during use of said sponge, said filament having a varying dimensional configuration along the length of filament to provide a distinctive pattern of the filament on an X-ray.
Claim 2
Dependent Claim
53 words
A surgical sponge, comprising an absorbent fabric; and an elongated radiopaque filament integrally bonded to fibers in said fabric to prevent dislodgment of said filament during use of said sponge, said filament having a varying dimensional configuration along the length of filament to provide a distinctive pattern of the filament on an X-ray.
Claim 3
Dependent Claim
20 words
The sponge of claim 1 wherein said filament is elongated and extends substantially between opposed marginal edges of said fabric.
Claim 4
Dependent Claim
28 words
The sponge of claim 2 wherein said fabric includes a pair of edges connecting said opposed edges, and the elongated filament is spaced from said pair of edges.
Claim 5
Dependent Claim
20 words
The sponge of claim 1 wherein said filament comprises a thermoplastic material compressed in a molten condition into said fabric.
Claim 6
Dependent Claim
37 words
A surgical sponge, comprising: an absorbent fabric; and an elongated radiopaque filament positioned on said fabric and having a varying width along the length of filament to provide a distinctive pattern of the filament on an X-ray.
Claim 7
Dependent Claim
37 words
A surgical sponge, comprising: an absorbent fabric; and an elongated radiopaque filament positioned on said fabric and having a varying width along the length of filament to provide a distinctive pattern of the filament on an X-ray.
Claim 8
Dependent Claim
34 words
The sponge of claim 5 wherein said filament has a plurality of zones of increased width spaced along the length of the filament and a plurality of regions of reduced width intermediate said zones.
Claim 9
Dependent Claim
23 words
The sponge of claim 6 wherein said zones are spaced from each other approximately an equal distance along the length of said filament.
Claim 10
Dependent Claim
16 words
The sponge of claim 5 wherein said filament is integrally bonded to fibers in said fabric.
Claim 11
Dependent Claim
37 words
A surgical sponge, comprising: an absorbent fabric; and an elongated radiopaque element positioned on said fabric and having a varying thickness along the length of element to provide a distinctive pattern of the element on an X-ray.
Claim 12
Dependent Claim
37 words
A surgical sponge, comprising: an absorbent fabric; and an elongated radiopaque element positioned on said fabric and having a varying thickness along the length of element to provide a distinctive pattern of the element on an X-ray.
Claim 13
Dependent Claim
34 words
The sponge of claim 9 wherein said element has a plurality of zones of reduced thickness spaced along the length of said element, and a plurality of regions of increased thickness intermediate said zones.
Claim 14
Dependent Claim
21 words
The sponge of claim 10 wherein said element includes a plurality of areas of maximum thickness intermediate said regions and zones.
Claim 15
Dependent Claim
