Abstract

Catheter and catheter assemblies for extracorporeal circulation of body fluids, such as blood, are described. A catheter includes a septum that divides an internal lumen into fluidicly isolated drainage and infusion lumens. The infusion lumen extends along only a portion of the axial length of the catheter and terminates at an infusion opening defined by the circumferential wall of the elongate member of the catheter. The drainage lumen extends the full axial length of the catheter and is laterally accessible via first and second sets of drainage openings.

Description

technical field [0001] The invention relates to the field of medical instruments. More specifically, the present invention relates to catheters and catheter assemblies for extracorporeal circulation of body fluids. Specific examples described in this disclosure relate to catheters for extracorporeal oxygenation of blood. Background technique [0002] Extracorporeal circuits are used in various medical treatments. For example, extracorporeal membrane oxygenation (ECMO) uses an extracorporeal circuit to oxygenate the blood of patients whose hearts and lungs cannot, for various reasons, achieve adequate natural gas exchange. During ECMO, oxygen depleted blood is sent outside the body to an extracorporeal circuit where artificial gas exchange takes place. After oxygenation, the blood is injected back into the body's natural circulation. [0003] Catheters are a key component of any extracorporeal circuit because they provide the point at which bodily fluid(s) enter and exit ...
