Embodiment Construction

[0024] As used herein, the terms "proximal", "proximal", or "rear ..." refer to the part of the structure that is closer to the medical staff, while the terms "distal ...", "distal" or "Front..." and the like refer to the part of the structure that is further away from the medical staff. As used herein, the term "subject" refers to a human patient or other animal. The term "healthcare provider" refers to a doctor, nurse or other care provider and may include support personnel.

[0025] now refer to Figures 1 to 3 , the catheter assembly 10 includes a catheter 20 , a sleeve 30 , and a telescoping tube assembly 40 . Catheter 20 includes an elongate body 22 having a septum 24 extending along the length of elongate body 22 to define a first lumen 26 and a second lumen 28 on opposite sides of septum 24 . The first and second chambers 26, 28 may have a generally D-shaped cross-section, such as figure 2 shown in . Additionally or alternatively, the first and second cavities 26...

Abstract

A catheter assembly includes a catheter, a collar, and an extension tube assembly. The catheter includes a leading end portion and a trailing end portion. The collar is supported on the trailing end portion of the catheter. The extension tube assembly includes a first section and a second section, each section independent of the other section and including a substantially rigid body portion and a compressible extension tube portion. The body portion of each of the first and second sections is independently engageable with the trailing end portion of the catheter. The collar is configured to engage the first and second sections of the extension tube assembly to secure the extension tube assembly to the trailing end portion of the catheter.

Description

technical field [0001] The present invention relates generally to catheter assemblies, and more particularly, to catheter assemblies having replaceable components. Background technique [0002] Catheters are flexible medical devices that facilitate the withdrawal of fluids from and the introduction of fluids into body cavities, ducts, and blood vessels. Catheters find particular application during hemodialysis, in which blood is withdrawn from a blood vessel for processing and then returned to the blood vessel for circulation. Known hemodialysis catheter assemblies include multi-lumen catheters, such as double-lumen or triple-lumen catheters, by dedicating one lumen to withdrawing blood from a vessel and another lumen to returning treated blood to blood vessels allowing bi-directional fluid flow within the catheter. During an exemplary hemodialysis procedure, a multilumen catheter is inserted into the body and blood is drawn through the arterial lumen of the catheter. The...
