A brachytherapy catheter needle formed as an elongate pointed leading part terminating in a coupling piece for fixation of the brachytherapy catheter behind and in line with the leading part. Such a structure is by nature stiff. The brachytherapy catheter needle can be pulled entirely through the tissue, so that the brachytherapy catheter can be cut at the exit side. This method can be performed faster and more effectively than with the conventional brachytherapy catheter needles. The brachytherapy catheter needle according to the invention is preferably relatively short and solid and can be inserted into the tissue in front of the brachytherapy catheter tube. This provides the advantage that the needle can be made of relatively stiff design, enabling a better straight guidance.
