1. A uterine device, comprising:
a shaft sized and configured to access a uterus of a patient, the shaft being coupled to a fluid source;
fluid delivery ports disposed on a distal portion of the shaft;
a distal balloon positioned proximally on the shaft from the fluid delivery ports;
a central balloon positioned proximally to the distal balloon, the central balloon configured to contact an internal os and a cervical canal of the patient when the distal balloon is positioned in the uterus against the internal os;
a proximal balloon positioned proximally to the central balloon and spanning a first portion of the cervical canal and a second portion of a vagina of the patient when the distal balloon is positioned in the uterus against the internal os and the central balloon is positioned within the cervical canal; and
a controller operably coupled to the distal balloon, the central balloon, and the proximal balloon, the controller configured to fully inflate the proximal balloon after inflating the distal balloon such that the proximal balloon is fully inflated along the first portion of the cervical canal and the second portion of the vagina, wherein the uterine device is configured such that inflation of the proximal balloon causes the uterine device to move proximally to position the distal balloon against the internal os,
wherein the uterine device is configured to deliver a heated vapor to the uterus.
