The 12F Tri-Flow Triple Lumen Catheter is a short term dialysis catheter made of thermosensitive polyurethane. The catheter has three separate lumens allowing continuous blood flow. The venous (blue) and arterial (red) lumens may be used for hemodialysis and apheresis treatments. The middle (clear) lumen is independent from the two dialysis lumens and may be used for intravenous therapy, blood draws and infusion of medications.
