Approval Order Statement 
Approval for the following modifications: 1) reduced recommended saline flow rate (reduce by ~50%; 2) increase in number of irrigation holes (from 6 to 56); 3) decrease in size of irrigation holes (from 0. 016¿ to 0. 0035¿ diameter); and 4) modified tip electrode material (from 90% platinum/10% iridium to 80% palladium/20% platinum). The device, as modified will be marketed under the trade names uni-directional carto xp thermocool sf nav catheter, uni-directional carto 3 thermocool sf nav catheter, and uni-directional thermocool sf catheter and is indicated for catheter based cardiac electrophysiological mapping (stimulating and recording) and, when used with a compatible rt generator, for the treatment of: a) type i atrial flutter in patients age 18 or older; b) drug refractory recurrent symptomatic paroxysmal atrial fibrillation, when used with compatible three-dimensional electroanatomic mapping systems. The thermocool sf nav diagnostic/ablation deflectable tip catheter provides location information when used with compatible carto ep navigation ssytems. The biosense webster thermocool sf diagnostic/ablation deflectable tip catheter and related accessories are indicated for use in catheter-based cardiac electrophysiological mapping (stimulating and recording) and, when used with a compatible rf generator, for the treatment of type i atrial flutter in patients age 18 or older.
