A device for verifying occlusion of the fallopian tube in a female subject includes an elongate member dimensioned to be slidably disposed within the uterine cavity of the subject. An interrogation element is positioned at the distal end of the elongate member. The interrogation element may include a visualization element such as a camera, ultrasonic transducer, MRI imaging element, or the like. In still other aspects, the interrogation element may include an electrode that is used to measure the electrical properties of the occlusion site. For example, the electrode may be used to measure electrical impedance.
