A New Generation of Hemodialysis Catheters
Meet the Pristine™ Long-Term Hemodialysis Catheter, BD's next generation of hemodialysis catheters. It is a side-hole free hemodialysis catheter with a unique Y-Tip™ distal lumen design.
- Side-hole free tip is designed to help minimize thrombus adhesion that can be associated with side-hole catheters and to help facilitate blood clot aspiration prior to hemodialysis treatment.
- The Pristine™ Catheter demonstrated high flow rates at low pressures1 and with its symmetric tip demonstrated low recirculation rates in both forward and reverse2.
- The catheter is uniquely designed to help facilitate accurate Y-Tip™ distal lumen placement in the mid right atrium. The notched tip is designed to help resist positional occlusion.

- Tested using 19 cm (n=38); 23 cm (n=40); 28 cm (n=38); 33 cm (n=40) and 55 cm (n=39) tip-to-cuff length Pristine™ Long-Term Hemodialysis Catheters. Flow test performed using glycerin: water solution with a viscosity of 3.2-3.7 cP at 36-38° C. At an arterial maximum pressure of -250 mmHg or less, the maximum flow rates observed were 500 mL/min (19 cm through 33 cm tip-to-cuff lengths) and 379 mL/min (55 cm tip-to-cuff length). In order to show the the flow rate at -250 mmHg pressure limit, the linear curve fit for the negative side was used to find the flow rate corresponding to indicated pressure, then the flow rate value was used to estimate the positive venous pressure. Bench data on file. Bench data may not necessarily correlate to clinical performance. Different test methods may yield different results.
- Tested using 55 cm tip-to-cuff length Pristine™ Long-Term Hemodialysis Catheters (n=37). Recirculation test performed using 5% saline as blood simulant at a blood flow rate of ~5 liters/minute and catheter flow rate of 350 mL/min. The mean recirculation rates were 2.7% in forward flow and 2.8% in reverse flow. Bench data on file, Becton, Dickinson and Company, Tempe, AZ.
