PulseSelect™ pulsed field ablation (PFA) system

Setting a new standard in safety. Engineered for efficiency.

The PulseSelect™ PFA system is setting a new standard in safety for AF ablation supported by robust clinical evidence.1 Now FDA approved, the PulseSelect™ PFA system offers a new approach to cardiac ablation and can be implemented across your preferred workflow, driving efficient and predictable procedures.


Real-time, temperature-controlled ablation

As the only open-irrigated RF catheter with industrial diamonds to optimize power based on tissue surface temperature, the DiamondTemp ablation catheter with RealTemp™ is safe and effective, and has demonstrated procedural efficiencies compared to contact force-sensing RF.​2

Watch as four experienced EPs share how the DiamondTemp ablation system uses direct tissue surface temperature measurement to create effective lesions.

Arctic Front™ family of cryoballoons

Unmatched cryoballoon technology

The leader in cryoballoon technology, bringing over 16 years of clinical experience, and more than one million patients treated.3 The only ablation catheter indicated to treat first-line paroxysmal and persistent atrial fibrillation (AF) patients.4–7

Freezor™ family of cardiac cryoablation catheters

Focal cryoablation for patients big and small

The Freezor and Freezor™ Xtra catheters are the only FDA-approved ablation catheters for the treatment of AVNRT in both pediatric* and adult patients. Cryoablation is the safe choice with no incidence of AV block reported.8–23

* Indicated for patients over two years of age.
