Surgical system and method of use

A method of resecting tissue, comprising:

• positioning a stretchable structure having a thin wall around an exterior of a uterus, where the stretchable structure comprises an electrically conductive material that enhances a sensitivity of a sensor system;
• introducing a probe into an interior of the uterus, the probe having an inner sleeve and an outer sleeve, wherein a working end of the probe includes a motor-driven cutter on the inner sleeve exposed at a window of the outer sleeve, wherein the working end carries an electrical component of the sensor system that is configured to detect the electrically conductive material of the stretchable structure such that the sensor system detects the motor-driven cutter approaching a surface of the uterus;
• activating the motor-driven cutter to resect uterine tissue at the window with the motor-driven cutter;
• providing an electrical current to the electrical component and using a controller to monitor impedance between the electrical component and the electrically conductive material of the stretchable structure, wherein the controller is configured to detect that the electrical component on the working end of the motor-driven cutter is approaching the electrically conductive material of the stretchable structure from the interior of the uterus;
• and removing a substantial volume of the uterus from within the interior of the uterus without the motor-driven cutter perforating the surface of the uterus to prevent dispersion of potentially malignant tissue outside of the uterus.
