A balloon tamponade catheter for controlling uterine postpartum hemorrhage has an elongated body with a balloon at a marginal distal end of the elongated body for insertion into the uterus. The balloon preferably has a pear-shaped appearance. The balloon may have a first hemisphere that is located on the catheter distal to second, smaller hemisphere. The first hemisphere has a plane of maximum diameter that is larger than the second hemisphere's plane of maximum diameter. Between the two planes of maximum diameter, the balloon comprises a transition section. In some cases, the transition section bows inward towards the elongated body when the balloon is uninflated and/or inflated. Additionally, the elongated body preferably does not extend distally past the distal end of the first hemisphere.
