Abstract
A flow control tip for a catheter comprises a partition dividing the catheter into first and second lumens, a first orifice fluidly connected to the first lumen and a second orifice fluidly connected to the second lumen, the first orifice being proximal to the second orifice, an elongate protrusion extending along a portion of the partition substantially along a centerline of the elongated body and a deflecting surface extending at an angle relative to the protrusion to direct flow from the first orifice away from the centerline.
