This application relates generally to a trans-cervical balloon catheter. The catheter may have an elongated body for insertion into the uterus. Located distally on the elongated body, the catheter may have a balloon that has a substantially conical-shaped proximal end when inflated. The balloon may comprise a proximal origin and a distal origin with a longitudinal midpoint located midway between the origins. The balloon may have a plane of maximum diameter located between the distal origin and the longitudinal midpoint. The proximal end of the balloon may taper from the plane of maximum diameter towards the proximal origin of the balloon in any manner that gives the proximal end of the balloon a conical-shaped appearance.
