    摘要： The invention is directed to an intracorporeal device for myocardial revascularization of a patient's heart tissue by at least one burst of RF energy over an interval of about 1 to about 500 msec, preferably about 30 to about 130 msec. The intracorporeal device has an elongated insulated, electrical conducting shaft with an uninsulated distal tip which is configured to emit RF energy. The uninsulated distal tip has a diameter of about 0.025 to about 0.2 inch, preferably about 0.04 to about 0.08 inch and a length of about 0.1 to about 5 mm, preferably about 1.5 to about 3.5 mm.

    摘要： The disclosure is directed to a tissue ablation device comprising an elongate probe, with a tissue ablation member located at the deflectable distal end of the probe, which is configured to access a patient's heart. The elongate probe is attached at its proximal end to a handpiece which is ergonomically designed to fit within the hand of the operator. The handpiece houses an advancement mechanism which is mechanically coupled to the tissue ablation member and can be used to axially translate the tissue ablation member in relation to the elongate probe. An activation mechanism is housed within the advancement mechanism and is coupled to the advancement mechanism in such a manner that the operator can simultaneously activate and advance the tissue removal member with one finger or thumb. The handpiece also houses a deflection actuator which applies tension to a tensile member which deflects the distal end of the probe.

    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.
