Introducing IRRAflow®

A fundamental redesign of fluid management technology developed by leading neurosurgeons, the IRRAflow system demonstrates a significant technological step forward compared to other currently available treatment options. IRRAflow’s transformational technology provides a controlled fluid exchange system that allows the neurosurgeon to actively manage intracranial pressure and CSF drainage.

IRRAflow System

IRRAflow consists of a control unit and disposables (dual-lumen catheter and tube set) to offer four fully integrated and synchronized functions:

1.
A fluid exchange system with an irrigating pump and drainage mechanism that interact with a dual lumen catheter to both supply and evacuate fluid from the body. The system is also synchronized to monitor local body cavity pressure within a preprogrammed range.
2.
A monitoring and measuring system for intracranial pressure based on a method that uses a fluid column for accuracy and reliability.
3.
A safety alarm that can be customized for each patient and is activated when the pressure is higher or lower than the preprogrammed range.
4.
The programmable periodic flush irrigation prevents blockage of the catheter and associated surgical complications.

Dual-Lumen Catheter

With its use of a patented dual-lumen catheter design, IRRAflow allows the user to transition from passive drainage to active fluid management. By using one of these two lumens to periodically irrigate fluids through the catheter, the catheter tip remains unobstructed, ensuring the accuracy of the pressure measurement and the patency of the drainage. Unlike existing EVDs that become blocked up to 40%1 of the time during the drainage process, the IRRAflow system has been designed to prevent these blockages from forming.

Irrigation + Aspiration

The IRRAflow system also employs an active irrigation and aspiration cycle to optimize the drainage process and patient outcomes. With its proprietary software ensuring a continuous cycle of automated flushing and gravity-driven drainage, the process of the evacuation of fluids, infection, and debris can be improved to reduce ICU and recovery time. At the same time, the patient’s intracranial pressure is consistently monitored and managed.
