The Brevi-XL™ is similar to the Brevi-Kath® with the added versatility of selective distal end stiffness by adjusting the stylet. The catheter maintains a round atraumatic tip. The stylet runs the entire length of the Brevi-XL™ catheter. The Brevi-XL™ is designed to provide greater durability, ease in placement, and precise directional control (1:1 torque). In addition, these catheters are radiopaque and include the Racz® Bend Marks to better highlight key navigational reference marks.
