Dilators configured to be used over the top of conventional endoscopes are disclosed. Dilator 100 includes a dilating surface 340 and an endoscope outlet 342 at its distal end, the inner diameter of which is chosen to closely approximate the outer diameter of the endoscope. In use, the endoscope may serve as a guide to the dilator 100 both during initial and during dilation of, for example, an esophageal stricture. A safety handle 310 is also provided which gives feedback to the operator based on the amount of applied axial force, which helps to reduce the chances of injury.
