A device for simulating catheterization in a body channel of a patient comprising, a catheter having an elongated shaft, an inflation balloon on the shaft, and an inflation lumen extending along the shaft and communicating with the balloon. The device has a sleeve of flexible material defining a cavity to receive the portion of the shaft containing the balloon, with the sleeve having a sufficiently small width such that the balloon contacts walls of the sleeve when inflated. The sleeve has a line of weakness which ruptures when the balloon is sufficiently inflated unless relieved of pressure prior to rupture of the sleeve.
