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
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.
