[A new cannula for the introduction of catheters or other cannulas into the vascular system]

A new cannula is described consisting of a 25 cm. tube without a syringe attachment. It can be used for the introduction of other annuals (Hettler method) or for guide wires (Seldinger technique). The use of this cannula instead of the usual means of introducing catheters makes it possible to learn the technique quickly and to achieve correct placing of the cannula in the vascular lumen. The radiologist, using this method, achieves a safe and routine method very quickly. In this way angiographic examinations are made simpler they can be performed more quickly and the number of complications is reduced.
