Abstract
Disclosed is a flexible, reinforced, multiple lumen catheter. This catheter includes an elongated, flexible, tubular element extending about a central axis, and including embedded therein at least one filament extending in a helical path about the central axis. The inner surface of the tubular element defines an interior region. The catheter also includes an elongated divider element having elongated lateral edges. These edges are integral with, and extending from, portions of the inner surface of the tubular element. At least two lumens are defined in the interior region of the tubular element on opposing sides of the divider element. Also disclosed is a method for assembling the flexible, reinforced, multiple lumen catheter.
