Hemostatic system for body cavities

A device for controlling bleeding in a body cavity, said device comprising:

• a first expandable balloon having an inner and outer surface;
• an expandable pilot balloon;
• and
• a hemostatic shroud;
• said shroud surrounding at least part of said outer surface of said first expandable balloon and comprising a gel-forming absorbent composition;
• said first expandable 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, inflation of said first expandable balloon to occupy said cavity and to press said shroud against the inner wall of said cavity;
• said expandable pilot balloon and said first expandable balloon in fluid communication with each other such that the pressure inside said expandable pilot balloon equals the pressure inside said first expandable balloon.

A method for controlling bleeding on an inner wall of a body cavity or passageway comprising:

• inserting into said cavity a first inflatable, non-stretchable balloon surrounded at least in part by a hemostatic shroud comprised of a fabric and a gel-forming absorbent composition, said first inflatable, non-stretchable balloon fluidly connected to an inflatable, non-stretchable pilot balloon;
• inflating said first inflatable, non-stretchable balloon therein;
• compressing said shroud against said inner surface of the cavity where bleeding is to be controlled;
• and
• monitoring the pressure within said first inflatable, non-stretchable balloon by touching said inflatable, non-stretchable pilot balloon.

A device for plugging a cavity,

• said device comprising a catheter, a balloon, and marker material;
• said catheter providing for the delivery and insertion of the balloon into said cavity;
• said catheter further including means for expanding said balloon, and, upon expansion thereof, for resisting contraction thereof;
• said balloon being releasably connected to the catheter;
• and
• said marker material being adapted to indicate a cavity which has been plugged.

A device for plugging a cavity,

• said device comprising a catheter system for delivery and insertion into said cavity of a filling material, the filling material, and marker material for indicating a cavity which has been plugged;
• said filling material being releasably connected to the catheter;
• said filling material being designed to be retained within the cavity;
• and
• said filling material being selected from the group consisting of a non-solid curable material which is cured into a hardened state inside the cavity, a fibrous material, and a resiliently-deformable member.
