Specific and fast sampling from the surface of an organ

  • Continous microdialysis sampling

  • Collect biomarkers

  • Minor invasive

  • Minor stress to the organ

  • Introduced during surgery

The sterile CE-marked, single use Onzurf Probe allows continuous monitoring in gastro-intestinal organs such as esophagus, stomach and liver. The OnZurf Probe has a unique attachment site, which allows the probe to be easily fixated on the surface of the organ without penetrating the tissue and causing unnecessary stress to the organ.

Apart from the CE-marked indication mentioned above experimental studies have demonstrated that surface microdialysis measurements from the heart, liver and intestine reflect the metabolic processes that occur inside the heart muscle, the liver parenchyma and intestinal lumen, which makes OnZurf Probe an excellent sampler intended for monitoring purposes.

OnZurf Probe is available in two different designs, OnZurf Probe Continuous and OnZurf Probe On Demand. OnZurf Probe Continuous has longer inlet – and outlet tubes for direct use with a microdialysis analyzer. The outlet tube of OnZurf Probe On Demand protrudes from its male luer connector so that dialysate can be collected from the bottom of the connected microvials. The OnZurf Probe inlet tubing can be connected to a Microdialysis Pump. The samples can be analyzed with IVD instruments or sent to clinical laboratory for further analysis with e.g. HPLC. The OnZurf Probe can also be connected to the microdialysis instrument CliniSenz Analyzer (under development) for direct patient monitoring of extracellular lactate trends.
