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.*

*Success 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:
  • Provides consistent movement in response to contact force using precision spring
  • Sends accurate location reference signal via location sensor and transmitter coil
  • Promotes consistent lesion formation
  • Reduces ablation time 2
  • Improves outcomes with more stable catheter-tissue contact force3
