IRRAflow® Advantages

Enhanced Drainage

Current drainage systems, such as external ventricular drains (EVDs), are vital tools in managing a patient’s ICP during neurocritical care situations. By draining excess fluid, an EVD plays a critical role in stabilizing the intracranial pressure (ICP) of these critically ill patients, which can facilitate recovery. Unfortunately, EVDs are generally primitive systems that rely solely on gravity alone, and as a result, they have been plagued by blockages that can lead to inefficient drainage and other complications.

IRRAflow addresses this inefficient drainage by returning control of the drainage process to the clinician.  This is accomplished with a therapeutic treatment called active fluid exchange.  The IRRAflow patented dual-lumen catheter design facilitates active fluid exchange by enabling irrigation with physiologic fluids and drainage of pathological material. This fluid irrigation also helps to keep solid particulate in suspension, making it easier to subsequently drain. This concept can hereby address the underlying reasons that result in historic shortcomings typically associated with passive drainage alone: catheter blockages and infection.

Integrated, Continuous ICP Monitoring

Elevated intracranial pressure (ICP) is a common cause of neurological damage and death in patients with any neurosurgical disorder. Continuous ICP monitoring has been clinically proven in studies since 2012 to decrease patient mortality rates.1 Given this, it is vital that you have a product that not only has continuous monitoring, but also has a drainage catheter that remains unobstructed during the procedure.

IRRAflow provides these attributes by combining drainage, irrigation, and pressure monitoring into one easy-to-use integrated fluid management system. This innovative, new monitoring system automates pressure data collection, allows for custom alarms when pressure rises, and actively manages ICP through its proprietary fluid exchange technology.

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.

Irrigation-Aspiration2

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. IRRAflow’s dual lumen catheter was designed to enable active fluid exchange by enabling irrigation with physiologic fluids and drainage of pathological material. IRRAflow‘s Active Fluid Exchange mechanically cleanses the catheters tip thus potentially facilitating disruption of clot and or bacteria.3,4
