Abstract

A multi-lumen catheter and method for inserting same in a patient is disclosed. The catheter includes an elongated, central, multi-lumen tube portion having a proximal end and a distal end. The central tube portion has a substantially cylindrical outer shape and is internally segmented into a plurality of lumens. A distal branch portion includes a plurality of single-lumen distal extension tubes. Each distal extension tube has a proximal first end and a distal second end. The proximal first end of each distal extension tube is connected to the distal end of the central tube portion such that the single lumen of each distal extension tube is in fluid communication with one of the plurality of lumens of the central tube portion. A proximal branch portion includes a plurality of single-lumen proximal extension tubes. Each proximal extension tube has a distal first end and a proximal second end. The distal first end of each proximal extension tube is connected to the proximal end of the central tube portion such that the single lumen of each distal extension tube is in fluid communication with one of the plurality of lumens of the central tube portion. Each lumen of the central tube portion and the lumens of the distal and proximal extension tubes in fluid communication therewith define a flow path through the catheter. Selectively attachable hub connectors are provided for selective attachment to the distal extension tubes and connection of the catheter to a fluid exchange device.

Abstract

A method of inserting a multi-lumen catheter assembly. First, an incision is made near the area to be catheterized. The proximal portion of the multi-lumen catheter tube is then inserted into the area to be catheterized. A subcutaneous tunnel is created, and the first end of the tunnel is near the incision. The catheter tube is then routed through the subcutaneous tunnel and pulled tube through a second end of the subcutaneous tunnel. The hub body is then securely attached to the catheter tube by connecting the connection cover to the hub body by threaded engagement. In a preferred embodiment the hub body is attached to the catheter tube by backfitting the connection cover over the catheter tube. A compression sleeve is also backfit over the catheter tube. The cannulae of the hub body are inserted into the lumens of the catheter tube to create fluid communication therebetween.
