Abstract

A plastic catheter system for irradiation therapy by the afterloading method, made from: a flexible plastic matrix having one or more catheters or sheaths embedded therein, and having a synthetic fabric contained within the plastic matrix or on a side of the plastic matrix, wherein: PA1 a) when the plastic matrix has all flat surfaces, the synthetic fabric is located on a side opposite the location of the one or more catheters and covers the entire side in area, PA1 b) when the plastic matrix is cylindrical in shape, the synthetic fabric is located in a lower portion of the cylindrical plastic matrix and coaxially arranged, and PA1 c) when the plastic matrix is of a shape other than a) and b), the synthetic fabric is located on a side facing away from a side from which irradiation occurs.
