Abstract
A bolus tip for a multi-lumen catheter includes a first channel terminating distally in a first opening, and a second channel terminating distally in a second opening. The first opening may be positioned proximal the second opening along a longitudinal axis of the bolus tip and may be positioned on a side of the bolus tip opposite that of the second opening. The first and second openings may extend through an outer wall of the bolus tip to a dividing section. The bolus tip may also include a third channel sized for accommodating a guidewire.
