Abstract
A microdialysis probe having a center tube surrounded by a thin dialysis tube (3), which is located between two tubular fitting parts (2, 5). With the purpose of reinforcing the probe and facilitating its withdrawal without any part of the probe remaining despite the fragility of the dialysis tube, the distal end of the center tube from within is fixedly joined to the distal fitting part (2), which also has a larger diameter than the dialysis tube (3).
