Real-time, temperature-controlled ablation

DiamondTemp™

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.​1

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

Unmatched cryoballoon technology

Arctic Front™ family of cryoballoons

The leader in cryoballoon technology, bringing over 16 years of clinical experience, and more than one million patients treated.2 The only ablation catheter indicated to treat first-line paroxysmal and persistent atrial fibrillation (AF) patients.3-6

Focal cryoablation for patients big and small

Freezor™ family of cardiac cryoablation catheters

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.7-22

* Indicated for patients over two years of age.
