NAVISTAR™ Catheter
NAVISTAR™ Catheter is a steerable, multiple electrode catheter with a deflectable tip designed to facilitate electrophysiological mapping of the heart and to transmit radiofrequency (RF) current to the catheter tip electrode for ablation purposes. For mapping, the catheter is used with the CARTO™ 3 System, and an appropriate location reference device. For ablation, the catheter is used in conjunction with a compatible RF generator and a dispersive pad (indifferent electrode).
Also available NAVISTAR™ DS Catheter and NAVISTAR™ DS Bi-Directional Catheter.

Disclosures: In the US, 4mm Catheters (NAVISTAR® Catheter, CELSIUS® Catheter, EZ STEER® Catheter (NAV and Non‐NAV)) have a “General Indication” for creation of endocardial lesions in patients 4 years of age and older. This “General Indication” includes treatment of Ventricular Tachycardia.
The Johnson & Johnson and its affiliates QDOT MICRO™ Catheters and related accessory devices are indicated for catheter-based cardiac electrophysiological mapping (stimulating and recording) and, when used in conjunction with a compatible radiofrequency generator, for the treatment of:• Type I atrial flutter in patients age 18 or older.• Drug refractory recurrent symptomatic paroxysmal atrial fibrillation, when used with compatible three-dimensional electroanatomic mapping systems. The Johnson & Johnson and its affiliates QDOT MICRO™ Catheters provide real-time measurement of contact force between the catheter tip and heart wall, as well as location information when used with CARTO™ 3 Navigation System.
Important information: Prior to use, refer to the instructions for use supplied with this device for indications, contraindications, side effects, warnings and precautions. Caution: US law restricts this device to sale by or on the order of a physician.
