Abstract
A double lumen catheter having a fluid intake lumen and fluid return lumen of equal cross-sectional area, separated by an internal divide wherein blood flow characteristics are increased and maintained in a continuous fashion by a series of apertures positioned on both the intake side and return side of the catheter is disclosed. The apertures are in such position and configuration that they communicate with one another to prevent the accumulation of fibrin or other matter within the lumens as fluid enters into or exits from those lumens.
