Abstract
A catamenial device such as a tampon which comprises a segment of a rapidly re-expandable hydrophilic polymeric foam held in compression to less than 50 percent of its original dry volume and a constraining means holding said segment in compression which is adapted to provide lubrication for insertion of said segment into an animal's body cavity and to thereafter rapidly disintegrate, wherein said constraining means comprises a capsule prepared from a water-soluble alkylene oxide polymer such as poly (ethylene oxide). The devices of the present invention exhibit surprising lubricity and shelf-life, and are economically prepared.
