Claim 0:
1. 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 extending from a proximal end to a distal end and comprising a treatment device and a predetermined section at the distal end, the distal end of the introducer being contoured or tapered to assist in inserting the introducer through the cervical canal and into the uterine cavity while preventing perforation of surrounding tissue, the treatment device configured to activate a treatment modality at the distal end of the introducer;
a sensor located at the predetermined section; and
a controller;
wherein, in use:
the sensor generates a first status signal while the predetermined section of the introducer is located inside of the cervical canal and the sensor is in intimate contact with tissue of the cervical canal;
the sensor generates a second status signal while the predetermined section of the introducer is located inside of an area that is wider than the cervical canal and the sensor is free of the intimate contact with the tissue;
the controller generates a signal which indicates the sensor is free of the intimate contact with the tissue and the predetermined section 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 predetermined section of the introducer is located in the uterine cavity; and
the controller does not generate the signal which indicates the sensor is free of the intimate contact with the tissue and the predetermined section of the introducer is located in the uterine cavity when the second status signal is not preceded by the first status signal.
