The medical device includes a catheter with a catheter shaft and a balloon attached to a distal end of the catheter shaft and a flexible, thin-walled sheath extending over the balloon. The sheath includes a balloon-enveloping portion having an inner diameter sized to fit closely around the balloon and a collar distal to, and having an inner diameter slightly smaller than the inner diameter of the balloon-enveloping portion. The collar terminates in an opening, and a tab extends distally from a wall of the sheath.
