Abstract

The invention relates to a catheter port for supplying an active substance to an active site which is distant from the port. According to the invention, the housing (1) of the port is designed to have two parts, an upper housing part (7) and a lower housing part (6). The upper housing part (7) holds an insertion part (10) in a clamping manner in a housing recess (8) of the lower housing part (6), wherein a chamber (11) is arranged in said insertion part for receiving the active substance with the interpositioning of a punctured membrane (17) that can be pierced with an injection cannula. While the insertion part (10) and the chamber (11) can be manufactured from a material resistant to the active substance, preferably a heavier ceramics, the upper and lower housing parts may consist of a lighter biocompatible plastic material. It is advantageous that the patient only comes into contact with the upper and lower housing parts made of a biocompatible plastic material and not with the insertion part.
