PulseSelect™ PFA system design and safety features

Proven safety

Engineered with safety features from over 15 years of PFA research and supported by one of the safest IDE AF ablation trials to date and several independent studies1–17

Consistent efficiency

Rapid, effective pulmonary vein isolation (PVI)1 through predictable energy delivery and stable catheter control

Simplified adaptability

A plug-and-play PFA system compatible with existing workflows3 with real-time contact feedback seamlessly integrated into the PulseSelect™ generator display

PFA designed for simplified adaptability

A plug-and-play PFA system with an integrated proximity indicator to complement existing contact assessment techniques.

  • Nine active electrodes support real-time contact feedback, EGM sensing, pacing, and catheter visualization
  • Visualization on existing mapping systems
  • Compatible with intracardiac echocardiography (ICE) and fluoroscopy only workflows.

PulseSelect™ generator

  1. Automatic overcurrent detection for safe energy delivery
  2. R-wave gating for synchronization of energy delivery
  3. Test pulse for proximity detection to phrenic nerve
This is a family shot of the products that make up the PulseSelect™ pulsed field ablation system with callouts.

Trials

PULSED AF clinical trial1

PULSED AF evaluated the safety and effectiveness of the PulseSelect™ PFA system for the treatment of patients with paroxysmal and persistent atrial fibrillation and resulted in one of the lowest safety event rates of any AF ablation IDE trial to date.
