Balloon catheter system for draining fluids from hollow organs, body cavities or cysts and/or for supplying medication

A balloon catheter system for draining and/or supplying fluid from/into hollow organs, body cavities or cysts, comprising:

• a conduit catheter having an elongated body having an outer surface, said elongated body having an open proximal end and terminating in an open distal end configured to drain fluids from hollow organs, body cavities or cysts and/or for supplying medication, said proximal end containing a portion which traverses between a linear configuration in a first orientation and a non-linear configuration having at least one looped portion in a second orientation, said elongated body having a hollow needle guide duct separated from an interior lumen of said conduit catheter, said hollow needle guide duct having an opening that extends through said outer surface of said conduit catheter body and which is surrounded by an interior of an inflatable balloon;
• a removable hollow needle having a body sized and shaped to extend within and slidably enage said hollow needle guide duct, said hollow needle body having an opening which when inserted within said hollow needle guide duct rests at or near said hollow needle guide duct opening;
• said inflatable balloon affixed to a portion of the conduit catheter;
• a valve configured to prevent deflation of said balloon, said valve located in the neck of the balloon or the hollow needle guide duct of the conduit catheter, and
• a guide catheter having an elongated body of sufficient length to extend within and be positioned within the lumen of the conduit catheter thereby forming a coaxial alignment;
• characterised in that the conduit catheter with the removable hollow needle in the hollow needle guide duct can be inserted from outside into the hollow organ, the body cavity or cyst via the guide catheter provided in the conduit catheter, the balloon can be filled with filling medium via the removable hollow needle through said opening formed in the hollow needle guide duct and provided in the lumen of the balloon, wherein the balloon can be fixed in the hollow organ, body cavity or cyst and the hollow needle can be removed from the hollow needle guide duct of the conduit catheter after filling of the balloon, whereas the balloon and the conduit catheter remain in the hollow organ, body cavity or cyst.
