Abstract
A method of manufacturing a catheter which comprises a pair of separate lumens defining a higher pressure lumen and a lower pressure lumen, plus a side opening positioned adjacent the distal end of the catheter and communicating with the lower pressure lumen. A relatively thin tube defines the higher pressure lumen. One incorporates the relatively thin tube into a lumen of a relatively thick tube, followed by forming of the distal end of the high pressure lumen to curve rearwardly to form a proximally extending section having a proximal end. One then forms the side opening at a position adjacent the proximal end of the proximally extending section. The relatively thin tube may carry fibrous reinforcement to facilitate its use in defining the higher pressure lumen.
