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.
