1. A catheter type electrocatalytic sensor for determining glucose in body fluids, comprisinga tubular body of bio-compatible material that is subdivided into a first section, a second section and a third section,a sleeve-shaped reference electrode arranged between the first and the second, or between the second and the third section of the tubular body,a sleeve-shaped working electrode arranged--correspondingly--between the second and the third, or between the first and the second section of the tubular body, said working electrode having a slit extending in a longitudinal direction over its full length,a hydrophilic membrane stretched over the working electrode having ends which extend through the slit into the interior of the electrode and which is held in the slit by a wedge made of bio-compatible material,a counter-electrode which seals a first end of the tubular body, andlead wires to the electrodes arranged within the tubular body and which extend outside the tubular body through a second end of the tubular body.
