Packed and ready to use intraluminal catheter
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.
1. An intraluminal probe packed in a ready-to-use state and entirely arranged in a hermetic package, comprising
a tube provided with a hydrophilic coating and having a distal insertion end and a proximal holding end;
a nozzle connected to the proximal holding end of the tube, and comprising a canal communicating on one side with the tube and opening on the other side through an orifice; and
a removable stopper closing the orifice of the nozzle in a hermetic manner; and
wherein the package is fixed to the nozzle in a hermetic manner such that the nozzle defines two hermetic chambers in the package, a first chamber and a second chamber communicate only by means of a lumen of the tube and the canal in the nozzle;
wherein the tube is arranged in the first chamber containing a wetting fluid for the hydrophilic coating of the tube, thereby providing a slippery tube; and
wherein the orifice of the nozzle opens in a second chamber containing virtually no wetting fluid.
2. The intraluminal probe of claim 1 , wherein the package is formed of two package sheets of plastic material fixed around the nozzle in a hermetic manner.
3. The intraluminal probe of claim 2 , wherein the package is fixed to the nozzle by a welding or bonding process.
4. The intraluminal probe of claim 2 , wherein the two package sheets have at least one transversal tearing incision on both sides of the nozzle.
5. The intraluminal probe of claim 4 , wherein the two package sheets have two tearing incisions on a side of the tube, one tearing incision near the nozzle and another tearing incision further from the nozzle.
6. The intraluminal probe of claim 2 , wherein the two package sheets have low vapor permeability.
7. The intraluminal probe of claim 2 , wherein the two package sheets are formed of a polymer oriented such that a stretching direction of the polymer is transversal to a longitudinal direction of the tube.
8. The intraluminal probe of claim 1 , wherein the wetting fluid is a hydrous solution.
9. The intraluminal probe of claim 1 , wherein the hydrophilic coating of the tube swells in the presence of water.
