Abstract
Bleeding is controlled on an inner surface of a body cavity, including a non-vascular body passageway, by inserting into the cavity an expandable balloon which is covered by a hemostatic shroud, expanding the balloon, and compressing the shroud against the site of bleeding. The shroud may be released from the balloon. Subsequently, the balloon may be withdrawn from the body cavity, leaving the shroud in vivo to perform its hemostatic function. Optionally, the shroud can be withdrawn at some later point by the use of an extension “tail” which is included on the shroud. A method for controlling or preventing a bleeding situation within a pathological cavity is the use of filling material to plug the cavity.
Claims19
A method for controlling bleeding on an inner wall of a body cavity or passageway comprising:
- inserting into said cavity an expandable balloon surrounded at least in part by a hemostatic shroud comprising a gel-forming absorbent composition;
- expanding said balloon therein;
- and
- compressing the shroud against said inner surface of the cavity where bleeding is to be controlled.
A device for controlling bleeding in a body cavity,
- said device comprising an expandable balloon and a hemostatic shroud;
- said shroud surrounding at least part of the outer surface of said balloon;
- said shroud comprising a gel-forming absorbent composition;
- said balloon and shroud having a configuration adapted to permit insertion thereof into a body cavity wherein bleeding is to be controlled and, upon said insertion, expansion of said balloon to occupy said cavity and to press said shroud against the inner wall of said cavity.
