Hemostatic system for body cavities

Abstract

Bleeding is controlled on an inner surface of a body cavity 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 balloon may be disposed around a central tube to supply inflation medium. The tip of the device is soft to aid with insertion. The invention includes the corresponding devices and systems for such control of bleeding within a body cavity or passageway, as well as a method of making the devices.

1 - 15 . (canceled)  
   
   
       16 . A device for controlling bleeding on an inner wall of a body cavity or passageway comprising: 
 a central tube having a distal end;    a hemostatic shroud comprising a gel-forming absorbent composition, said hemostatic shroud disposed around said central tube; and    an expandable balloon having an unexpanded state and expanded state, said balloon disposed between said central tube and said hemostatic shroud;    wherein said balloon, in its unexpanded position, is rolled around said central tube.    
   
   
       17 . The device of  claim 16  wherein said rolled balloon extends beyond the distal end of said central tube.  
   
   
       18 . A device for controlling bleeding on an inner wall of a body cavity or passageway comprising: 
 a central tube having a central longitudinal axis, a wall, a proximal end, and a hole disposed in said tube wall;    a cylinder of fabric disposed around said central tube; and    an expandable balloon having an unexpanded state and an expanded state, said balloon disposed between said central tube and said fabric cylinder;    said hole allowing fluid communication between said central tube and said balloon.    
   
   
       19 . The device of  claim 18  wherein said balloon, in its unexpanded state, is rolled around said central tube.  
   
   
       20 . The device of  claim 18  wherein said hole is disposed perpendicular to the longitudinal axis of said central tube.  
   
   
       21 . The device of  claim 18  wherein said balloon wall thickness is between 0.03 mm and 0.15 mm.  
   
   
       22 . The device of  claim 18  wherein said fabric is comprised of two layers of a hemostatic shroud comprising a gel-forming absorbent composition.  
   
   
       23 - 27 . (canceled)  
   
   
       28 . A method for controlling bleeding on a surface of a passageway comprising: 
 inserting into said passageway an inflatable member, said member comprising an outermost, hemostatic gel forming absorbent composition;    expanding said inflatable member; and    compressing the composition against said inner surface of the cavity where bleeding is to be accorded.    
   
   
       29 . The method of  claim 28  wherein said passageway is a nasal passageway.  
   
   
       30 . A method of controlling bleeding on a surface of a body cavity comprising inserting a device as recited in  claim 16.
