Abstract: An instrument for controlling bleeding includes an outer shaft, an intermediate shaft telescopically received within a central lumen of the outer shaft, and an inner shaft telescopically received within a central lumen of the intermediate shaft, the inner shaft having a proximal end and a distal end that extends distally from the intermediate shaft. The instrument includes a hemostat disposed at the distal end of the inner shaft, and a fluid-resistant element connected to the distal end of the outer shaft and surrounding the hemostat. The fluid-resistant element has a breakable, fluid-resistant seal at a distal end thereof that protects the hemostat from fluids until the hemostat is delivered and deployed onto tissue. In one embodiment, the instrument includes an inflatable balloon to deploy and tamponade the hemostat.

Abstract: 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.

Abstract: An instrument for deploying hemostats has an intermediate shaft having a proximal end, a distal end, and a central lumen, and an inner shaft telescopically received within the central lumen of the intermediate shaft. The instrument includes an inflatable balloon, a first actuator for inflating the balloon, and a second actuator for moving the distal ends of the intermediate and inner shafts relative to one another for changing the shape of the inflated balloon. A proximal end of the balloon is secured to the distal end of the intermediate shaft and the distal end of the balloon is secured to the distal end of the inner shaft. The intermediate and inner shafts are moveable so that the inflated balloon has a toroidal shape and a flattened distal face. The inflated balloon has a major axis that is perpendicular to the longitudinal axis of the intermediate shaft.

Abstract: An instrument used for the delivery, deployment, and tamponade of a hemostat such as a topically applied hemostat includes an intermediate shaft having a proximal end, a distal end, and a central lumen extending to the distal end, and an inner shaft telescopically received within the central lumen of the intermediate shaft, the inner shaft having a proximal end and a distal end that extends distally from the intermediate shaft. The instrument includes an inflatable balloon having a proximal end secured to the intermediate shaft and a distal end secured to the inner shaft, a first actuator for inflating the balloon, and a second actuator for moving the distal ends of the intermediate and inner shafts relative to one another between a first position and a second position for changing the shape of the balloon when the balloon is inflated. The proximal end of the balloon is secured to the distal end of the intermediate shaft and the distal end of the balloon is secured to the distal end of the inner shaft.
