Abstract
A multi-lumen catheter and method for inserting same into a patient is disclosed. The catheter includes a multi-lumen catheter tube having a distal end, a proximal end, and a plurality of lumens therethrough. The catheter may include a single-lumen flush tube portion, the flush tube portion having a proximal end and a distal end, the proximal end of the flush tube portion being connected to the distal end of the catheter tube such that the single lumen of the flush tube portion is in fluid communication with each of the lumens in the catheter tube. A connector is provided having a proximal end, a distal end, and a longitudinal cavity extending therethrough. The cavity includes a coupling portion near the distal end of the connector, and the proximal end of the connector is connected to the distal end of the flush tube portion or the distal end of the catheter tube such that the cavity of the connector is in fluid communication with the single lumen of the flush tube portion or the plurality of lumens in the catheter tube. The coupling portion of the cavity of the connector is configured to receive a mating coupling portion of a medical device such as a trocar. The catheter device f…
