Claim:
1. Apparatus for treating a stricture in a body lumen comprising: 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, wherein the controller includes a plurality of instructions that, when executed by the controller, cause the controller to: (a) sense pressure exerted by the device on the stricture, (b) determine if enough force is being exerted on the stricture, (c) if enough force is being exerted, time with the controller the application of enough force, (d) determine 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, automatically decrement the force being applied to the stricture, (f) determine if not enough force is being applied to the stricture, (g) if not enough force is being applied to the stricture, automatically increment the force being applied to the stricture, and (h) automatically repeat (a)-(g) until, a desired pressure has been maintained on the stricture for a desired time to gradually relieve the stricture and widen the body lumen.
