Intravascular membrane oxygenator catheter

The Intravascular Membrane Oxygenator Catheter is a device that will oxygenate the blood in critically ill patients (children and adults) with sick and failing lungs. This catheter will off-load much of the work of the lungs thereby supporting the patient as the lungs heal from the underlying disease. This device will be inserted intravascularly and will diffuse oxygen into the blood that flows past it. Currently, patients with failing lungs refractory to maximal medical therapy with mechanical ventilation may be placed on ECMO (Extracorporeal Membrane Oxygenation), which is essentially an artificial lung outside the body. This is often a “last-ditch” but life-saving option that comes with risks and high costs. Others have tried to develop an intravascular membrane oxygenator to prevent the need for or delay deployment of ECMO but have been unsuccessful due to technical limitations. The Intravascular Membrane Oxygenator Catheter overcomes these limitations through a novel design that is easy to deploy, simple to use, and delivers a clinically significant amount of oxygen to the patient.
