    • 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.
    • 一种治疗体腔狭窄的方法和设备。 该方法包括:(a)感测治疗装置施加在狭窄上的压力,(b)确定是否有足够的力施加在狭窄上,(c)如果足够的力施加在狭窄上, (d)确定治疗装置是否对狭窄施加了太大的力,(e)如果施加到狭缝上的力太大,则减小施加到狭窄的力,(f)确定是否 (g)如果没有足够的力施加到狭窄上来增加施加到狭窄的力,并且(h)重复(a) - (g)直到(i)期望的压力 已经在组织上保持了所需的时间。 该设备包括用于在狭窄部上施加压力的装置,用于控制装置施加在狭窄部上的压力量的控制器以及用于感测由装置施加在狭窄部上的压力的压力传感器。
