Abstract

The invention relates to a medical catheter having a line (10) and a tip (20) which is connected to a distal section (11) of the line (10) and which has a smaller external diameter than the line (10), wherein the section (11) comprises a constant first internal diameter. The invention is characterized in that, in the rest state, the tip (20) has a second internal diameter which is smaller along the entire length of the tip (20) than the first internal diameter of the section (11). The invention further relates to a medical functional element and to an assembly comprising such a catheter and such a functional element.
