Learn More About Valved One-Step™ Centesis Catheters

The catheter’s low profile, tapered tip, and smooth transitions decrease resistance for less patient discomfort. Its echo-enhanced needle allows for more accurate placement. Four large drainage holes spiral around the catheter for maximum drainage.

Up to 34% LESS catheter tip penetration force and up to 16% FASTER flow rate. Safe, controlled insertion with decreased procedure times.

The valved One-Step centesis catheter is designed with an integrated self-sealing valve to minimize the risk of air entering the pleural space.
