The Centros (without side holes) and the CentrosFLO™ (with side holes) long-term hemodialysis catheters feature self-centering curved tips which automatically center the catheter ports within the middle of the vessel to maintain optimal blood flow and minimal recirculation rates, and enhance overall catheter performance. Designed by Dr. Stephen Ash, the 15F catheters feature a large internal lumen which allows for a flow rate up to 450 mL/minute.

Performance

Preshaped Curved Tips stabilize and center the catheter in the junction of the Superior Vena Cava (SVC) and Right Atrium (RA).

Distal Venous and Arterial Side Holes reduce intraluminal pressure and the likelihood of the catheter tips sucking up against the vessel wall.

Large Internal Lumen allows for a flow rate up to 450 mL/min.

Centered on Performance

The high performance CentrosFLO® long-term hemodialysis catheter from Merit Medical was designed with performance, safety, and ease of use in mind. The new SELF-CENTERING, curved-tip catheter has a greater separation between the arterial and venous tips. Its design is intended to optimize CATHETER PATENCY, and reduce fibrin sheath formation, thrombosis and vessel wall occlusions by keeping the tips of the catheter centered in the vessel and away from the vessel wall. Fibrin sheaths are a frequent cause of catheter malfunction and in a study of removed or exchanged hemodialysis catheters, 76% had fibrin sheaths.1,2,3 The CentrosFLO was designed for PERFORMANCE, SAFETY AND EASE OF USE.

Safety

Atraumatic Catheter Tip Design minimizes puncture or irritation of vessel walls.

Non-Traumatic Tunneler for more rapid loading of the catheter without risk to catheter tips.

Multiple Catheter Length Configurations accommodate variations in patient anatomy.

Ease of Use

Peelaway Sheath and Dilator insertion for initial placement.

Stiffening Stylet for over-the-wire placement and exchange.

Polyurethane Material provides ease of insertion and maintenance.

Study Results

A recent retrospective study conducted by Dr. Sarvan Balamuthusamy compared the performance of the self-centering split-tip hemodialysis tunneled catheter and the symmetric tip catheter. The results indicated that the self-centering split-tip catheter had statistically greater patency after 3 months with a slight advantage in clearance and blood flow.4
