Abstract
A bladder hemostatic catheter comprising, an elongated shaft having a lumen extending along the shaft, a tip at the distal end of the shaft, and an opening adjacent the distal end of the shaft communicating between the lumen and the outside of the shaft. The catheter has an inflatable balloon of elastic material covering a distal end section of the shaft, with the balloon having a proximal portion secured circumferentially around the shaft, and with the balloon defining a cavity intermediate the balloon and the shaft communicating with the opening. The balloon is capable of receiving 600 to 1000 cubic centimeters of fluid and assuming a generally spherical shape in an inflated state of the balloon. The catheter has valve means to permit passage of fluid from a source of fluid to the lumen while preventing passage of fluid from the lumen during inflation of the balloon.
