Method and apparatus for verifying occlusion of fallopian tubes

A device for verifying occlusion of the fallopian tube in a female subject comprising:

• an elongate gas delivery member having a lumen disposed therein, the elongate gas delivery member adapted for sealing engagement with the subject's uterus;
• a pressurized insufflation gas source coupled to the elongate gas delivery member, the insufflation gas source being in communication with the lumen of the elongate gas delivery member;
• and
• a flow meter interposed between the pressurized insufflation gas source and a distal end of the elongate gas delivery member for monitoring the flow rate of insufflation gas into the subject's uterine cavity.

A device for verifying occlusion of the fallopian tube in a female subject comprising:

• an elongate gas delivery member having a lumen disposed therein, the elongate gas delivery member adapted for sealing engagement with the subject's uterus;
• a pressurized insufflation gas source coupled to the elongate gas delivery member, the insulation gas source being in communication with the lumen of the elongate gas delivery member;
• a flow meter interposed between the pressurized insufflation gas source and a distal end of the elongate gas delivery member for monitoring the flow rate of insufflation gas into the subject's uterine cavity;
• and
• a pressure gauge interposed between the pressurized insufflation gas source and a distal end of the elongate gas delivery member for monitoring insufflation gas pressure of the subject's uterine cavity.

A method of verifying occlusion of a fallopian tube of a female subject comprising:

• providing a source of pressurized insufflation gas, the source of gas being coupled to a delivery member for sealingly engaging with the uterine cavity of the subject;
• delivering pressurized insufflation gas from the source to the uterine cavity;
• and
• measuring the pressure of the insulation gas contained within the uterine cavity over a period of time to detect the presence or absence of fallopian tube occlusion.

A method of verifying occlusion of a fallopian tube of a female subject comprising:

• providing a source of pressurized insufflation gas, the source of gas being coupled to a delivery member for sealingly engaging with the uterine cavity of the subject;
• delivering pressurized insufflation gas from the source to the uterine cavity at a target pressure;
• and
• measuring the flow rate of the insufflation gas into the uterine cavity required to substantially maintain the target pressure in order to detect the presence or absence of fallopian tube occlusion.
