Improved remote infusion catheter for prevention of acute limb ischemia in peripheral veno-arterial extracorporeal membrane oxygenation

Abstract This is an application of an improved remote infusion catheter in femoral artery veno-arterial extracorporeal membrane oxygenation (VA ECMO). VA ECMO is a critical technique for treating cardiogenic shock and cardiac arrest. However, acute limb ischemia has emerged as a severe complication of this treatment method, potentially significantly impacting patient prognosis and survival rates. We propose a modified remote infusion catheter method that utilizes a double male luer-lock connector to directly connect to the arterial sheath. This aims to address certain issues present in current methods, such as the absence of matching tubing in the kit.
