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.
