602003 A device for urethral stricture dilatation. The device includes: a dilator (70) having an elongate body (72) provided with a distal end tapered towards a distal tip (76), a proximal end (78) and a guidewire channel (74) extending therethrough； a guidewire (38) extending through the guidewire channel for guiding the dilator upon insertion； and a lubrication port at the proximal end of the elongate body for introduction of a guidewire lubrication fluid into the guidewire channel. The guidewire is provided with a stopper (50) for preventing the proximal end of the guidewire from passing through the guidewire channel towards the distal tip of the dilator. The stopper is adapted to receive a syringe for introducing guidewire lubrication fluid into the guidewire channel when the stopper is coupled to the lubrication port. The distal end of the dilator is curved towards the distal tip, and tapers from a diameter of between 14 French and 24 French to 2 French.
