Abstract

A micro-dialysis probe extending longitudinally between a proximal probe opening and a distal probe tip and having a supply line and a drainage line for a drip-feed solution. A tube may be provided for supporting the drainage line. A dialysis section, wherein the flow channel for the drip-feed solution experiences an inversion, is formed generally between the supply line and the drainage line, in the vicinity of the distal probe tip. The supply line and the drainage line are respectively arranged substantially side by side and together form the probe shaft of the micro-dialysis probe.
