Irrigated RF ablation catheters have become a mainstay device for treatment of atrial fibrillation and other cardiac arrhythmias. The introduction of catheter tip irrigation over a decade ago has allowed for safe use of higher energy levels resulting in improved outcomes, but has also impacted the ability of electrophysiologists (EPs) to accurately control and assess tissue temperature, and by extension, maximize safe and effective lesion creation.

 

 

 

 

 

 

 

Though there is an array of technologies that attempt to provide physicians with intra-procedural feedback, including conventional temperature sensors, such as thermocouples, or surrogate measurements of lesion creation such as contact force and electrocouple information, these technologies have a wide range of accuracy and reliability.

 

EPs have a plethora of information and tools at their disposal, but temperature remains the only true determinate variable to safe and effective lesion creation.

 

ACT’s TempaSure™ enabled irrigated RF ablation catheter leverages patent-protected microwave radiometry, which is not affected by saline irrigation, to accurately predict volumetric tissue temperature. This temperature information will empower EPs with the ability to more precisely control and monitor lesion formation in the heart at depth in real-time to minimize steam pops, char, thrombus and edema formation for an overall safer, more efficacious procedure.
