Used with the Worley Advanced LV Delivery system, the ONE Snare System provides another option for placing LV leads during challenging cases. Designed with a 15° tip curve to the 4F catheter and a 15mm snare loop electrophysiologists can retrieve and manipulate foreign objects in the coronary and peripheral vascular system, allowing for optimal lead position.1 Additionally, the ONE Snare delivery catheter provides 2.4x more buckle force than the competition.2
