Embodiment Construction

[0022] figure 1 A packaged intraluminal catheter according to the invention is shown. The catheter 10 has a tube 12 having a hydrophilic coating on its outer surface which is highly slidable when the coating is wetted, and a joint 14 consisting of a base 15 and a tube section 16 through which the tube section 16 passes through an opening 18. to the side opposite the tube 12.

[0023] exist figure 2 It should be noted that the opening 18 constitutes the outlet of the channel which opens in the joint 14 to the opening 36 which communicates with the bore of the tube 12 of the catheter.

[0024] exist figure 1 In , reference numeral 20 denotes a removable plug that is placed over the opening 18 and closes the opening 18 in a sealed manner.

[0025] According to the invention, the two sheets of the wrapper 22 form two chambers separated in a sealed manner, namely a first chamber 24 and a second chamber 26, in which the tube 12 is located and in which the tube 12 is located. T...

Abstract

The invention relates to an intralunimal catheter. It relates to a packaged intraluminal catheter comprising a tube (12) having a hydrophilic coating and having a proximal end connected to a tip (14)having a channel communicating with the tube (12) and an opening (18), the catheter being entirely contained in a smooth, transparent and waterproof packaging. The catheter contains a moveable cap (20) closing the opening (18), the packaging being sealingly fixed to the tip (14) so that it defines two sealed chambers (24, 26) which communicates only through the lumen of the tube (12) and the tip (14) channel, a first chamber (24) contains a wetting fluid for the tube (12) coating, and a second chamber (26) does not contain a wetting fluid. The invention can be used in urinary catheters.

Description

technical field [0001] The present invention relates to a packaged and ready-to-use intraluminal catheter. Catheters of this type are used for introduction into a body canal, such as the urethra. Background technique [0002] Intraluminal catheters are typically used in a packaged and either ready-to-use or ready-to-use wetted form. Since catheters of this latest type have the disadvantage of complicating the user's handling, attempts have been made to realize ready-to-use catheters. [0003] The resulting ready-to-use intraluminal catheter is thus provided within a sealed package containing a wetting fluid which, for example, causes swelling of the catheter's hydrophilic coating, thereby rendering the catheter highly slidable. Despite attempts to retain the wetting fluid on the side of the tube of the catheter, for example by absorbing plugs or by forming fluid pockets, the wetting fluid sometimes flows to the connector of the catheter which must be held by hand, causing ...
