    摘要： One method for performing procedures, such as vaginal hysterectomies, comprises engaging first and second energy transmitting elements against a lateral side of a uterus. The first and second energy transmitting elements are positioned against opposed surfaces of a tissue mass extending from and including a fallopian tube or round ligament to a tip of a cervix. Third and fourth energy transmitting elements are positioned against another lateral side of the uterus and against opposed surfaces of another tissue mass extending from and including another fallopian tube or round ligament to the tip of the cervix. Radio frequency or other high energy power is applied through the energy transmitting elements to the tissue masses. The power is applied for a time and in an amount sufficient to coagulate and seal the tissue masses within the energy transmitting elements. The coagulated tissue masses are then resected and the entire uterus removed.

    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(αei+βei−1+γei−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.
