The 70 Microdialysis Bolt Catheter is designed for implantation in brain tissue through the IM2 Bolt kit for 2 brain probes or the IM3 Bolt Kit for 3 brain probes from Integra. The catheter has a 130 mm long shaft and a membrane length of 10 mm. The shaft has a reinforced stainless steel section measuring 16.5 mm in length. This reinforcement is located where the compression screw of the bolt is to be tightened.

The  tip of the Catheter contains a gold tread, 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.
