Reinforced multiple lumen catheter

A multiple lumen catheter comprising:

• (a) an elongated, flexible, tubular element extending about a central axis and including embedded therein at least one filament extending in a helical path about said central axis, wherein the inner surface of said tubular element defines an interior region;
• and
• (b) an elongated divider element having elongated lateral edges, said lateral edges being integral with, and extending from portions of said inner surface of said tubular element, whereby at least two lumens are defined in said interior region on opposing sides of said divider element;
• wherein said tubular element comprises:
• (a) an elongated, flexible, tubular sheath having a substantially circular cross-section and an inner diameter substantially equal to D;
• (b) an elongated, flexible, tubular interior element having an outer surface, an interior surface, and a substantially circular cross-section, said outer surface having a diameter equal to D1 and said interior surface having a diameter equal to d, where D1 is less than D and d is less than D1, and wherein the interior surface of said interior element forms said inner surface of said tubular element;
• (c) said filament, said filament being wound about said outer surface of said tubular interior element;
• and
• (d) a flexible bonding material dispose dint he region between the outer surface of said interior element and the inner surface of said sheath.
