1. A method of using a medical device the method comprising:
positioning at least one sensor coupled to a first elongated member within a luminal space of a body;
positioning a second elongated member adjacent a portion of the first elongated member;
translating the second elongated member relative to the at least one sensor;
detecting, with the at least one sensor, a change in a physiological parameter and, based on the detected change in the physiologic parameter, determining a change in position of the second elongated member relative to the at least one sensor; and
transmitting a data signal from the at least one sensor responsive to the detected change in the physiologic parameter, the data signal being indicative of the relative location of the second elongated member with respect to the at least one sensor.
