Abstract

A surgical sponge, particularly of the neurosurgical class, comprising a fibrous web having attached to one surface thereof a locator string comprising a bundle of X-ray detectable monofilaments that are helically overwrapped as by a yarn. One or more of the components of a preferrred string is bondable to the web by means of heat and/or pressure.

Claims

1. A medical sponge comprising an absorbent web and a locator string attached to a surface thereof, said locator string comprising a plurality of individual radiopaque monofilaments assembled into an elongated bundle and a yarn encircling the circumference of said bundle and gathering the monofilaments into a coherent elongated member wherein the attachment between said locator string and said web extends substantially across one full dimension of said web.

2. A medical sponge comprising an absorbent web and a locator string attached to a surface thereof, said locator string comprising a plurality of individual radiopaque monofilaments assembled into an elongated bundle and a yarn encircling the circumference of said bundle and gathering the monofilaments into a coherent elongated member wherein said locator string is attached to said web by means of a bond therebetween that is developed by heat and pressure.
