    摘要: The present invention includes a system for delivering energy to an airway wall of a lung comprising an energy delivering apparatus and a PID controller having one or more variable gain factors which are rest after energy deliver has begun. The energy delivering apparatus may include a flexible elongated member and a distal expandable basket having at least one electrode for transferring energy to the airway wall and at least one temperature sensor for measuring temperature. The PID controller determines a new power set point base on an error between a preset temperature and the measured temperature. The algorithm can be Pi+1 = Pi + G(αe i + βe i-1 + γ e i-2 ) where α, β and γ are preset values and α is from 1 to 2; β is from -1 to -2; and γ is from -0.5 to 0-5. In another variation, the controller is configured to shut down if various measured parameters are exceeded such as, for example, energy, impedance, temperature, temperature differences, activation time and combinations thereof. Methods for treating a target medium using a PID algorithm are also provided.

    摘要: A device for delivering energy to an airway of a lung, the device comprising:
    an elongate member including a proximal end, a distal end, and a lumen extending therebetween;
    an actuating member operably coupled to the proximal end;
    an electrode assembly operably coupled to the distal end, wherein the electrode assembly includes a plurality of electrodes; and
    an operating member extending from the actuating member, through the lumen of the elongate member, and coupled to a distal end of the electrode assembly, wherein the operating member is configured to move reciprocally relative to the elongate member via actuation of the actuating member, wherein reciprocal movement of the operating member is configured to transition the electrode assembly between a first configuration and a second configuration, and wherein the operating member is biased distally by a resilient member in the actuating member.
