Multiple-lumen catheter
First Claim
1. A multiple-lumen catheter for use in the delivery or the withdrawal and delivery of fluids to a patient, said catheter comprising:
- a) an elongate generally cylindrical body having an axial passageway extending the length thereof;
b) a septum extending across the interior of the body and along the length thereof in order to divide the body into first and second lumens;
c) a bolus extending from a distal end of the body, the bolus having a tube connector section at one end, a nose section at the other end and a passage section between the connector section and the nose section,the nose section having a solid bullet-shaped construction; and
d) the passage section containing an axial passage portion adjacent the connector section and a radial passage portion adjacent the nose section, the axial passage portion in fluid communication with the first and second lumens, the radial passage portion forming a single port through the side of the bolus and in fluid communication with the first and second lumens, the septum terminating in the axial passage portion of the bolus.

Abstract
A multiple-lumen catheter is disclosed that includes a catheter tube having a generally elongate cylindrical body having an axial passageway extending the length thereof. A septum extends across the interior of the body and along the length thereof in order to divide the body into first and second lumens. A bolus extends from a distal end of the body. The bolus has a passage section including an axial passage portion and a radial passage portion. The axial passage portion is in fluid communication with the first and second lumens. The radial passage portion includes a single port through the side of the bolus whereby the first and second lumens are in fluid communication with the port. According to another form of the invention, the radial passage includes a first port and a second port therein.
