Abstract
A catheter is provided that includes multiple passages within a catheter body. These passages are arranged in a way so as to maximize the usable space within the catheter body. More specifically, multiple tubes are positioned within a central lumen of the catheter. Both the tubes and the central lumen are used as passages for various functionality of the catheter, such as communication of air or fluids. By sharing the free space within the central lumen of the catheter, the flow area of this passage is maximized as compared with simply using an extruded lumen for each passage. Hence, the catheter can allow the addition of more passages than similarly sized prior art catheters.
