The sterile single use 67 Intravenous Microdialysis Catheter is intended for continuous microdialysis monitoring in the peripheral venous system or in Cerebrospinal Fluid (CSF) e.g. via an External Ventricular Drain (EVD) for up to three days. The 67 IV Microdialysis Catheter allows energy related metabolites, drugs and other small substances to diffuse into the catheter reflecting accurate concentrations in the blood or CSF. 

In blood monitoring the 67 IV Microdialysis Catheter is applied simply using a standard peripheral venous catheter and can be used intravenously for up to 72 hours of monitoring. The clean samples and possibility for frequent sampling without discomfort for the patient makes it ideal for clinical research. The catheter is available in 4 different versions of membrane and shaft lengths.In blood monitoring, recovery performance is optimized by using the type with 30 mm membrane at 0.3 μl/min flow rate.

When monitoring in CSF drain the 67 IV Microdialysis cathether is inserted into a Stop cock connector that is attached to the outflowfrom a CSF drain pump e.g. LiquoGuard®

  • For blood or CSF monitoring up to 72 hours

  • Easy insertion by standard PVC
