Positioning method and apparatus for delivering vapor to the uterus
First Claim

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, the proximal balloon configured to span from the cervical canal into a vagina of the patient when the distal balloon is positioned against the internal os; and
a controller disposed within the handle and operably coupled to the distal balloon, the central balloon, and the proximal balloon, the controller configured to inflate the proximal balloon after inflating the distal balloon to create a compression force that pulls the uterine device and the distal balloon proximally to engage against an interior portion of an internal os of the patient.

Abstract
A method and system of providing therapy to a patient'"'"'s uterus. The method can include the steps of inserting a uterine ablation device into the uterus; expanding a distal anchor; inflating a proximal balloon to pull the distal anchor proximally and seat the distal anchor against the internal os of the uterus; inflating a central balloon to seal the cervix; delivering vapor from the uterine ablation device into the uterus; and condensing the vapor on tissue within the uterus. The can include a cervical collar adapted to place a distal portion of the device within the uterus when the cervical collar contacts an external os of the cervix.
