The Procedure

The Otricathâ„¢ infuses agents into a vein against blood flow and uses the natural direction of flow to return them to the catheter.


This creates an isolated treatment zone that maximizes local therapeutic concentrations while preventing agents from escaping to the rest of the body (Figure 1).


Anticancer agents delivered by standard catheters flow directly into an artery and travel uncontrolled to all areas of the body, causing damaging side-effects.


This results in inadequate therapeutic uptake while causing damaging side-effects (Figure 2).
