Catheter patency is vital for the delivery of hemodialysis and effective, long-term vascular access for patients with end-stage renal disease. Tunneled catheter thrombosis, as a result of venous thrombosis or the formation of fibrin sheaths, is a leading cause of catheter failure. Thrombosis can occur when the distal tip of the catheter comes in contact with the vessel wall, which can lead to vessel wall injury and fibrin sheath formation. The tip designs of many available long-term hemodialysis catheters on the market today allow for the tip of the catheter to come in contact with the vessel wall.
The CentrosFLO represents an innovative approach to the design of long-term hemodialysis catheters. The self-centering, curved-tip catheter has a greater separation between the arterial and venous tips compared to a symmetric-tip catheter. Its design is intended to optimize catheter patency, and to reduce fibrin sheath formation, thrombosis and vessel wall occlusions. This unique tip design keeps the tips of the catheter centered in the vessel and away from the vessel wall reducing vessel wall trauma.
An independent retrospective study1 conducted by a vascular access center showed 94.7% patency in the CentrosFLO catheter versus the competitor's catheter, which had a patency rate of only 75% at 3 months.
