Integrity testing method and apparatus for delivering vapor to the uterus
First Claim
1. A method of performing a procedure on a uterus of a patient, comprising:
- performing a uterine integrity test comprising;
inserting a uterine device into the uterus of the patient;
delivering gas or fluid from an inflow lumen of the uterine device into the uterus;
measuring a flow rate of the gas or fluid as it is delivered into the uterus;
determining that the uterus is sealed if the flow rate decreases below a flow rate threshold value;
eliminating retrograde flow from the uterus back through the uterine device with a one way valve disposed in the inflow lumen; and
after performing the uterine integrity test and determining that the uterus is sealed, performing a patency test for the uterine device comprising;
delivering gas or fluid from the inflow lumen of the uterine device into the uterus;
removing gas or fluid from the uterus with an outflow lumen of the uterine device;
determining that the uterine device is not clogged or embedded in tissue if a flow rate of gas or fluid removed from the uterus is observed through the outflow lumen of the uterine device.

Abstract
A method and system of providing therapy to a patient'"'"'s uterus is provided, which can include any number of features. The method can include the steps of inserting a uterine device into the uterus and performing a uterine integrity test to determine that the uterus is intact and not perforated. If it is determined that the uterus is not perforated, a patency test can be performed to determine that the uterine device is not clogged or embedded in tissue. If the uterus is intact and the device is not clogged or embedded in tissue, the uterus can be treated with the uterine device, e.g., uterine ablation. Systems for performing these methods are also disclosed.

25. A method of performing a procedure on a uterus of a patient, comprising:
performing a uterine integrity test comprising; inserting a uterine ablation device into the uterus of the patient; delivering fluid from an inflow lumen of the uterine ablation device into the uterus; measuring a flow rate of the fluid as it is delivered into the uterus; determining that the uterus is sealed if the flow rate decreases below a flow rate threshold value; and eliminating retrograde flow caused by uterine contractions from flowing back through the inflow lumen with a one way valve disposed in the inflow lumen. - View Dependent Claims (26)

27. A method of performing a procedure on a uterus of a patient, comprising:
-
inserting a uterine ablation device into the uterus of the patient; delivering fluid from an inflow lumen of the uterine ablation device into the uterus; measuring a flow rate of the fluid as it is delivered into the uterus; distending the uterus with the delivered fluid; determining that the uterus is sealed if the flow rate decreases below a flow rate threshold value; eliminating retrograde flow caused by uterine contractions from flowing back through the inflow lumen with a one way valve disposed in the inflow lumen; determining that the uterine ablation device is not clogged or embedded in tissue if a return flow of fluid is observed through an outflow lumen of the uterine ablation device; treating the uterus of the patient without reducing distension pressure with the uterine ablation device immediately following the step of determining that the uterine ablation device is not clogged and the uterus is sealed. - View Dependent Claims (30)
