Abstract
A device for promoting the clotting of blood in body cavities includes a flexible body portion; an expandable member located on the flexible body portion; and a blood clotting material attached to the expandable member. When used, insertion of at least a portion of the blood clotting material into the body cavity causes at least a portion of the blood clotting material to contact blood emanating from a bleed site. Methods of providing therapies to tube-shaped organs include the steps of providing suitable devices having expansion capabilities, positioning the devices at the appropriate bleed sites, and expanding the devices to cause blood clotting materials to contact the bleed sites. Materials that may be used as the blood clotting material include zeolites, molecular sieve materials, diatomaceous earth, clay, silica-based materials, oxidized cellulose, carboxymethyl cellulose, bioactive glass, biological hemostats, chitosan, and combinations of the foregoing.
