Abstract
An improved bolus tip design for use in a multi-lumen catheter for the simultaneous injection and withdrawal of fluids to and from a patient. The improved bolus tip has a rounded elongate body consisting of an interfacing section and a nose section. A first channel opens to a first bolus cavity, which is formed into the bolus tip, and a second channel either extends through the nose section of the bolus tip, forming an outlet therefrom, or terminates at a second bolus cavity similar to the first bolus cavity. In the latter configuration, the second bolus cavity is located longitudinally between the fist bolus cavity and a tip of the nose section on a side directly opposite the first bolus cavity. The second bolus cavity is in fluid communication with the second channel.
