Abstract
A method and apparatus for treating a stricture in a body lumen. The method comprises (a) sensing pressure being exerted by a treatment device on the stricture, (b) determining if enough force is being exerted on the stricture, (c) if enough force is being exerted on the stricture, timing the application of enough force, (d) determining if too much force is being exerted by the treatment device on the stricture, (e) if too much force is being applied to the stricture, decrementing the force being applied to the stricture, (f) determining if not enough force is being applied to the stricture, (g) if not enough force is being applied to the stricture incrementing the force being applied to the stricture, and (h) repeating (a)-(g) until (i) a desired pressure has been maintained on the tissue for a desired time. The apparatus comprises a device for exerting pressure on the stricture, a controller for controlling the amount of pressure the device exerts on the stricture, and a pressure sensor for sensing the pressure being exerted on the stricture by the device.
