Staggered tip design reduces thrombus formation
Clinical observations indicate that conventional catheters with sideholes have considerably lower blood flow rates than those without sideholes[1]. In line with this statement, the specially engineered GamCath HighFlow catheter has no sideholes - a significant advantage that helps prevent clotting, one of the most frequent complications in catheter application.
Kidney-shaped lumen design allows for greater blood flows
The GamCath HighFlow catheter is designed with an arterial lumen which is 20% larger than the venous lumen. In terms of absolute pressure, both arterial and venous pressure levels are the same. In a standard double-D lumen design with equally distributed lumens, the arterial pressure is always greater than the venous pressure, causing reduced blood flow. With its improved lumen design for a better surface-to-volume ratio, the GamCath HighFlow catheter allows best possible flow rates at low arterial pressure.
