The Tun-L-XL™/24 catheter features a stylet that runs the entire length of the device. This spring-reinforced catheter is designed to provide maximum distal tip stability and control. The stylet is manufactured to extend to the tip of the catheter, which provides for precise directablity and placement. This stylet can be retracted to provide similar flexibility to the Tun-L-XL™/24 or can be fully inserted to provide maximum stiffness 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.
