Abstract:
1. An instrument for controlling bleeding comprising: an intermediate shaft having a proximal end, a distal end, a longitudinal axis extending between the proximal and distal ends of said intermediate shaft, and a central lumen extending to the distal end; an inner shaft telescopically received within the central lumen of said intermediate shaft, said inner shaft having a proximal end and a distal end that extends distally from said outer shaft; an outer shaft having a proximal end, a distal end, and a central lumen extending to the distal end thereof, wherein said intermediate and inner shafts are disposed within the central lumen of said outer shaft; a balloon having a proximal end secured to the distal end of said intermediate shaft and a distal end secured to said inner shaft, wherein the distal end of said balloon is inverted and the inverted distal end is secured to the distal end of said inner shaft; a hemostat distal to and in contact with the distal end of said balloon; a first actuator for inflating said balloon; a second actuator for moving the distal ends of said intermediate and inner shafts relative to one another for changing the shape of said balloon, wherein upon inflation said inflated balloon has a leading face that forms a distal-most end of said instrument and said inflated balloon has a major axis that is perpendicular to the longitudinal axis of said intermediate shaft; and a third actuator coupled with said outer shaft for moving the distal end of said outer shaft proximally relative to the distal ends of said intermediate and inner shafts.
