Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The CentrosFLO™ Tunneled Dialysis Catheter is a 15F dual-lumen, double-D shaped catheter similar to other "split tip" catheters in the market: outflow ("arterial") and return ("venous") lumens that separate, a subcutaneous Dacron® cuff, extension sets with clamps and caps, and construction from Carbothane® material. The CentrosFLO™ catheter contains two small pressure-relief holes near the tips.

The main difference of the CentrosFLO catheter is in the design of the tip. Current "split tip" catheters have two free ends that diverge, but are each essentially straight segments. In the CentrosFLO catheter the arterial lumen bends in an arc back towards the venous lumen, and the venous lumen bends towards the arterial lumen. As a result, the catheter has two curved surfaces that will rest against the vena cava wall to automatically "center" the catheter within the vein. The contact points of the catheter against the vena cava wall should be smaller and more disperse than with current straight-tip or split catheters. The following drawing demonstrates the design of the catheter, showing the current recommendation that the arterial port always be to the left.

The goal of the study is to demonstrate the stability of blood flow with the CentrosFLO catheter, during intermittent dialysis over a period of 6 months after placement. The investigators plan to enroll 10 patients in the study.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

CentrosFLO Long Term Hemodialysis Catheter

Schedule placement of catheter. Arterial tip of the catheter should be placed at or just above the junction of the right atrium and superior vena cava, with the arterial lumen on the left side of the catheter. The venous limb will extend into the right atrium. Catheter will be locked with the usual heparin lock solution for a newly placed catheter (at least 500 units per lumen). Fluoroscopic images will document tip position.
