IBR Combination Infusion & Microdialysis Brain Probe

Back to probes

The “IBR” style microdialysis probe facilitates infusing a treatment directly to the area being dialyzed. Unlike when administering a treatment systemically or via retrodialysis through a microdialysis probe membrane, when this probe is used, you can both target your treatment with anatomical specificity and know exactly how much drug you have administered. This can also address solubility or molecular weight issues of retrodialysis. The infusate exits the infusion cannula at the distal tip of the microdialysis membrane just outside the membrane lumen.
