A packed intraluminal probe comprises a tube provided with a hydrophilic coating and having a proximal holding end connected to a nozzle. The nozzle has a canal communicating with the tube and an orifice. The probe is entirely arranged in a flexible, transparent and hermetic package. The probe comprises a removable stopper which closes the orifice. The package is fixed to the nozzle in a hermetic manner such that the nozzle defines two hermetic chambers which communicate only by means of the lumen of the tube and the canal in the nozzle. A first chamber contains a wetting fluid for the coating of the tube, but a second chamber does not contain any wetting fluid.
