Abstract: A dilation device, comprises an elongated member extending longitudinally from a proximal end to a distal end, the elongated member sized and shaped to be received within a target area of an esophageal passage to dilate the target area, a projection extending along the elongated member from an outer surface thereof so that, when the elongated member is received within the target area, the projection extends into a wall of the esophageal passage, and a vibration mechanism which, when activated, vibrates one of the elongated member and the projection to break away a cell blockage within the target area.

Abstract: Methods and devices for locating and dilating a stricture are disclosed herein. In some embodiments, a device for locating strictures comprises an elongate member having a proximal end and a distal end. In at least some additional embodiments, a stopper is attached to the distal end of the elongate member. Additionally, in at least some examples, distance markings are disposed on the elongate member.
