Systems and methods for determining stricture characteristics are disclosed. A system for determining the characteristics of a stricture in a body lumen includes a dilation device, one or more sensors, and an output device. The dilation device is configured to be inserted in the body lumen at the location of the stricture. The one or more sensors are coupled to the dilation device for sensing characteristics of the dilation device during dilation. The output device is configured to indicate the characteristics of the dilation device. In order to determining the characteristics of the stricture, the dilation device may be inserted in the body lumen at the location of the stricture. The dilation device may then be inflated. Characteristics of the dilation device during inflation of the dilation device may then be sensed.
