This relates to treating an asthmatic lung and more particularly, relates to advancing a treatment device into the lung and treating the lung with the device. This also includes additional steps of treating the airway wall, applying energy or heat to the airway wall in an asthmatic lung.
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; βis 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.

The devices and methods generally relate to treatment of occluded body lumens. In particular, the present devices and methods relate to removal of the occluding material from the blood vessels as well as other body lumens. In some variations, the methods comprise providing a vascular device comprising a catheter body, a cutter assembly, a drive mechanism, a torque shaft, and a deflecting mechanism. The methods may further comprise operating the drive mechanism to cut occlusive material, operating the deflecting mechanism to deflect the cutter assembly, and rotating the distal end of the catheter body to sweep the cutter assembly.
