The sterile single use 70 Microdialysis Catheter is a highly flexible catheter designed for implantation in brain tissue. Two models of 70 Microdialysis Catheters are available with different shaft lengths suitable for stereotaxical as well as manual implantation.

The 70 Microdialysis Catheter is tunnelated under the scalp. It is then inserted into the brain tissue through a hole drilled in the skull bone.

The tip of the Catheter contains a gold thread, which makes it visible on a CT-scan in order to locate the exact position of the catheter in the brain.

The catheter inlet tubing is connected to a 106 Microdialysis Pump and the outlet ends in a microvial which collects the sample. The samples can be analyzed in the Microdialysis Analyzer for Glucose, Lactate, Pyruvate, Glycerol and  Glutamate.

  •  Minimally invasive

  • Can be implanted for several days
