Percutaneous Catheter for Lung Assist Device
Tech ID: 24949 / UC Case 2014-642-3
Dr. Ardehali has designed a catheter for extra-corporeal lung-assist devices that improves efficiency by stabilizing the catheter position and decreasing re-circulated blood.
Some patients with severe lung disease need to be treated with systems that oxygenate the blood using extra-corporeal, bedside machines (ECMO). Currently used catheters for ECMO systems suffer from two primary disadvantages: blood that has already been oxygenated often gets re-circulated back through the system; and the catheter’s efficiency and blood flow characteristics have a strong dependency on position. Therefore, when a patient inevitably moves, such as after waking up, inefficiencies invariably arise.
Dr. Ardehali, from the department of cardiothoracic surgery, has designed a catheter that overcomes the inefficiencies of currently used ECMO catheters by having both more stability and a better fluid flow design that reduces blood re-circulation.
