A vascular catheter for cannulating arterial or venous vessels, for example in the fermoral region, or the vena cava and/or the right auricle of the heart, comprises a flexible tube having blood passage orifices in the nature of holes at its anterior and insertion end to be inserted in the vessel or the auricle, which tube is directly or indirectly connectable at its other open end to a conduit or appliance. A piston-like closure member is movable to and fro in the tube in lengthwise direction thereof, such that it covers and thereby closes at least same of the blood passsage orifices in one position in the tube and clears these orifices in other positions. Preferably, the closure member is so fashioned that in its closure position, it covers all blood passage orifices in the insertion end of the cathether tube.
