Patent ID: 8366733

Claim:
An instrument for controlling bleeding comprising: a rigid outer shaft having a proximal end, a distal end, and a central lumen extending between the proximal and distal ends; a rigid inner shaft disposed within the central lumen of said outer shaft, said inner shaft having a proximal end, a distal end that extends beyond the distal end of said outer shaft, and a central lumen extending between the proximal and distal ends thereof; an inflatable balloon having a proximal end secured to said outer shaft and a distal end that is inverted, wherein said inverted distal end of said balloon is secured to said inner shaft; a first actuator in communication with said inflatable balloon for selectively inflating said balloon; a shaft actuator connected with at least one of said shafts for selectively moving said outer and inner shafts relative to one another, wherein upon inflation of said balloon, said shaft actuator is engageable for moving said outer and inner shafts from a first position in which said inflated balloon has a rounder leading face to a second position in which said inflated balloon has a flatter leading face, and wherein said shaft actuator is adapted to hold said outer and inner shafts in the second position for maintaining the shape of said flatter leading face of said inflated balloon as said flatter leading face is used to apply pressure for controlling bleeding; and a hemostat in contact with said inverted distal end of said balloon, wherein as said balloon is inflated said expanding balloon deploys said hemostat in contact with said inverted distal end of said balloon, and wherein said deployed hemostat conforms to said flatter leading face when said outer and inner shafts are in the second position.
