ABSTRACT:
A device for introducing medical instruments into hollow organs, canals, or vessels of a human or animal body, has a tip which is provided with an indentation. At least a first nozzle, aimed rearwardly with respect to the tip and connected to an inner chamber of the tip, extends through the wall of the indentation and is connected to a source of pressurized fluid. The pressurized fluid escaping from the nozzle exerts a force on the tip to advance it into the body, and a instrument coupled to the nozzle tip is thereby transported through the body.
