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 Microdialysis Pump and the outlet ends in a microvial which collects the sample. The samples can be analyzed in the ISCUSflex Microdialysis Analyzer for Glucose, Lactate, Pyruvate, Glycerol, Glutamate and Urea or sent to the laboratory for further analysis.

Microdialysis shall not be used as the sole basis for diagnosis or therapy.

  • For bolt implantation

  • “Gold-Tip” visible on CT

  • For early detection of brain ischemia and vasospasm
