An instrument for controlling bleeding includes an outer shaft having a central lumen extending between proximal and distal ends thereof, and an inner shaft disposed within the central lumen of the outer shaft, the inner shaft having a central lumen extending between proximal and distal ends thereof
An instrument for controlling bleeding includes an outer shaft having a central lumen extending between proximal and distal ends thereof, and an inner shaft disposed within the central lumen of the outer shaft, the inner shaft having a central lumen extending between proximal and distal ends thereof. The instrument has an inflatable balloon with a proximal end secured to the outer shaft and a distal end that is inverted and secured to the inner shaft. In one embodiment, the balloon has a spherical shape when the outer and inner shafts are in a first position and a toroidal shape when the outer and inner shafts are in a second position. The instrument includes an actuator for discharging a flowable material from the central lumen. In one embodiment, the instrument includes a stylet having barb-like features to attach a hemostat to the distal end of the instrument.

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. 2. The instrument as claimed in claim 1, further comprising a first conduit extending between said inner and outer shafts and toward the distal ends of said inner and outer shafts, wherein the first conduit has a first end in communication with said inflatable balloon and a second end in communication with said first actuator, wherein upon inflation said leading face projects distally of said distal end of said inner shaft for forming a distal-most end of said instrument. 3. The instrument as claimed in claim 2, further comprising a hub connector secured to the proximal end of said outer shaft, said hub connector having a first connection port for coupling said first actuator with the first conduit. 4. The instrument as claimed in claim 3, wherein said first actuator comprises a syringe having a barrel and a plunger, and wherein said plunger is depressible for introducing fluid into said balloon. 5. The instrument as claimed in claim 3, wherein said hub connector further comprises a second connection port that is aligned with the central lumen of said inner shaft. 6. The instrument as claimed in claim 5, further comprising a stylet having proximal and distal ends, a handle at the proximal end thereof, and hook-like barbs at the distal end thereof, wherein said stylet is insertable into said second connection port and through the central lumen of said inner shaft for positioning the hook-like barbs at the distal end of said inner shaft. 7. The instrument as claimed in claim 6, wherein said stylet further comprises threads or a tapered surface for securing said stylet to said hub connector. 8. The instrument as claimed in claim 5, further comprising a second actuator adapted to hold a flowable material, wherein said second actuator is securable to the second connection port of said hub connector. 9. The instrument as claimed in claim 8, wherein said second actuator comprises one or more barrels for holding said flowable material, one or more discharge openings alignable with the central lumen of said inner shaft, and one or more plungers that are depressible for dispensing said flowable material. 10. The instrument as claimed in claim 1, wherein said shaft actuator is engageable for selectively moving the distal ends of said shafts relative to one another for changing the shape of said inflatable balloon. 11. The instrument as claimed in claim 10, wherein said shaft actuator is adapted to selectively move the distal end of said outer shaft in a distal direction relative to the distal end of said inner shaft for changing the shape of said inflatable balloon secured to said outer and inner shafts. 12. The instrument as claimed in claim 1, wherein said hemostat is selected from the group consisting of medical textiles, flowable hemostats and flowable sealants. 13. An instrument for controlling bleeding comprising: a single shaft having a proximal end and a distal end;an inflatable balloon having a proximal end secured to said single shaft and a distal end that is inverted, wherein said inverted distal end of said balloon is secured to the distal end of said single shaft; andan actuator for selectively inflating said inflatable balloon, wherein upon inflation said inflated balloon has a toroidal shape having a flattened leading face at a distal-most point of said instrument adapted 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 flattened leading face. 14. The instrument as claimed in claim 13, said instrument further comprising barbs projecting from the distal end of said shaft. 15. The instrument as claimed in claim 14, wherein said shaft has a longitudinal axis extending between the proximal and distal ends thereof, and said barbs project along the longitudinal axis. 16. The instrument as claimed in claim 13, wherein the inverted distal end of said inflatable balloon is connected to a distal-most end of said shaft. 17. The instrument as claimed in claim 13, wherein said actuator for selectively inflating said inflatable balloon is coupled with a connection port located at the proximal end of said shaft. 18.
