摘要：A catheter arrangement for opening or closing hollow spaces, cavities, passagesand the like comprising a guide catheter and a dilatation catheter. A dilatation elementarranged at the dilatation catheter has an at least partially cylindrical foldable wall. Thecatheterization technique employable with such catheter arrangement contemplatesintroducing the guide catheter by forces applied in translatory and rotational directionand engaging at the surface layer of the guide catheter, into the near region of thehollow space to be opened or closed, then inserting the dilatation catheter through abore of the guide catheter, with the dilatation element having in its internal space anegative pressure in relation to the hollow space which is to be opened or closed. Thedilatation catheter is then inserted through the guide catheter to such an extent that thedilatation element arrives at the loation which is to be opened or closed and at thatlocation is dilated to a predetermined form and to the necessary diameter with a pre-selected excess pressure. There is also disclosed a method of manufacturing a dilatationelement for use with the catheter arrangement.
