Bi-Directional Catheter 
Deliver a new measure of success to your cardiac arrhythmia patients with the THERMOCOOL SMARTTOUCH® Catheter. Greater catheter stability results in more consistent contact force, producing more uniform lesions. The SMART-AF Trial evaluated the safety and effectiveness of the THERMOCOOL SMARTTOUCH® Catheter in patients with drug-resistant paroxysmal atrial fibrillation. One-year results from the trial showed patients experienced an overall success rate of 74 percent.1 Importantly, a subanalysis from the trial demonstrated an 88 percent success rate when contact force was within an investigator-selected range greater than or equal to 85 percent of time.2

2Success defined as freedom from any symptomatic atrial arrhythmia (atrial fibrillation, atrial flutter, atrial tachycardia) 12 months postprocedure when operator remained in the preset contact force range.The success rate improved to 81% (from 74%) when the investigator stayed within their preselected CF range =80% of the time (=85%: n=48; <85%: n=53). Further sub-analysis showed that when the contact force was within investigator-selected range =85% of time, success rate increased by 21% to 88% (=85%: n=32; <85%: n=73).
Features & Benefits:
  • Force-sensing technology that provides real-time measurement of contact force between the catheter tip and the heart wall
  • Tip electrode serves to deliver RF current from the RF generator to the desired ablation site
  • A thermocouple temperature sensor is embedded in the tip electrode
  • High-torque shaft with a bi-directional deflectable tip section containing an array of electrodes
