Potential to Reduce Occlusions & Infections

The evolution of EVD technology has been limited, so neurosurgeons and ICU staff still deal with catheter occlusion rates up to 40%1 as well as infection rates that can range from 2 – 24%2. At IRRAS, we believe that it is time for a needed step forward in fluid management technology that addresses these clinical challenges and improves outcomes.

IRRAflow®’s innovative closed system design responds to these issues with its use of a proprietary dual-lumen catheter and automated software to drain excess fluid in a controlled fashion. On a regular basis, IRRAflow provides an irrigation pulse to flush the catheter, which keeps the holes in the catheter tip unobstructed and prevents catheter blockages from forming. By doing so, IRRAflow eliminates the need for nursing staff to manually inject fluids to keep the catheter open and also reduces the likelihood that the drainage catheter will have to be replaced to allow drainage to continue. By reducing these possibilities, IRRAflow’s completely closed system removes opportunities for outside pathogens to be introduced, which can reduce the chance of infection for the patient.
