Pulsed Field Ablation (PFA)

Volt

The Volt™ PFA System is investigational and not approved for sale in any geography. It consists of the following components:

  • Volt™ PFA Catheter, Sensor Enabled™: A novel balloon-filled basket with 8 active splines. It is designed for therapy delivery, pacing, and the collection of electrical and anatomical data when used with the EnSite™ X EP System.
  • Current™ PFA Generator: The streamlined user interface includes waveform selection, tissue proximity display, electrode selectivity, and therapy count tracking. Abbott's Current PFA Generator is designed for intuitive use and is built to be extensible for future PFA catheter types.
  • Agilis™ NxT Steerable Introducer, Dual Reach™ (13 F): The best-in-class Agilis™ platform now in a 13 F diameter for use with larger French size catheters. In addition, the Volt PFA System works with a 13 F inner diameter introducer such as Agilis NxT Steerable Introducer. Visit the product page.

PFA System Studies

Volt CE Mark Study

Before being used with patients, the Volt PFA System underwent extensive laboratory testing. Following this, the CE Mark Study was the first clinical research to investigate the Volt PFA System's performance in treating human patients. The purpose of this study was to gather data demonstrating that the Volt PFA System functions as intended in a clinical setting and to establish its safety and effectiveness for treating atrial fibrillation.

CE Mark Study Results

In the Volt CE Mark feasibility sub-study, acute effectiveness was achieved in 99.2% (127/128) of treated PVs (96.9% of subjects, 31/32) with 23.8 ± 4.2 PFA applications/subject.

CE Mark Feasibility Study

Volt AF IDE Study

This clinical research study is intended to demonstrate safety and effectiveness of the Volt™ PFA System for the treatment of symptomatic, recurrent, drug-refractory paroxysmal and persistent atrial fibrillation.

Pre-Clinical Abstracts

2023 APHRS Volt Chronic Canine

Chronic Safety and Efficacy of a Novel Balloon Basket PFA Catheter in a Canine Model with Multi-Level Dosing. PVI using PFA with or without 3D mapping system resulted in a similar acute outcome and safety profile. Procedure times were significantly shorter in the fluoroscopy only group. There were no PFA-specific complications. Abstract Number: AB-885-AT

2023 APHRS Abstract: Volt with LivePoint

Tissue contact is important for an effective pulsed field ablation: Evidence from preclinical in-vitro and in-vivo studies. This reasearch demonstrates the importance of tissue contact (LivePoint™ Display) in achieving successful chronic PVI. Abstract Number: AB-749-AT

2023 HRS Volt PFA Swine SF2 x2 Nominal

Chronic Safety and Efficacy of a Novel Basket PFA Catheter in a Swine Model. We report on first animal data from a Novel PFA Catheter in a chronic Swine Model.

2024 HRS Volt Chronic Canine

Chronic Safety and Efficacy of a Novel Balloon Basket PFA Catheter in a Canine Model with Multi-Level Dosing. Investigate the safety and efficacy of PFA therapy using a novel, balloon-based catheter in a chronic canine model.

2025 Volt Hemolysis Profile

Hemolysis Profile of a Novel Balloon-Filled Basket Pulsed Field Ablation Catheter. No acute complications were observed during PFA application, and all six canines survived until termination. As presented at AF Symposium 2025.

The Volt PFA Catheter, Sensor Enabled and Current PFA Generator are investigational devices. LIMITED BY FEDERAL (OR U.S.) LAW TO INVESTIGATIONAL USE. These products are not available for sale in any geography.
