With the growth of obsesity, difficult IV starts are more and more common. Get the edge with the Introcan Safety Deep Access IV Catheters from B. Braun. Specially designed for deep vein access, they're available in four long sizes — from 1.25 inches to 2.5 inches. The extra length means more of the catheter resides in the deep veins, reducing the likelihood of complications and restarts. Use them for difficult-access patients, obese patients and procedures requiring ultrasound guidance. Deep Access IV Catheters are also designed to extend indwell time and prevent needlesticks.
