Claim 14:
15. A medical device comprising:
an introducer configured to be inserted into a uterine cavity through a cervical canal which is narrower than the uterine cavity, the introducer including a treatment device configured to activate a treatment modality at a distal end of the introducer;
a sensor at the distal end of the introducer; and
a controller;
wherein the introducer is configured to place the sensor in intimate contact with tissue during insertion of the introducer into the cervical canal and to remove the sensor from the intimate contact with tissue after the introducer is inserted into the uterine cavity;
wherein, in use:
the sensor provides a first status signal when the sensor is in intimate contact with the tissue inside of the cervical canal and provides a second status signal when the sensor is free of the intimate contact with the tissue;
the controller generates a signal which indicates the distal end of the introducer is located in the uterine cavity when the second status signal is preceded by the first status signal;
the treatment device activates the treatment modality at the distal end of the introducer after determining that the distal end of the introducer is located in the uterine cavity; and
the controller does not generate the signal which indicates the distal end of the introducer is located in the uterine cavity when the second status signal is not preceded by the first status signal.
