NS-PFA Catheter Ablation of Paroxysmal and Persistent Atrial Fibrillation With the Pulse Biosciences CellFX System

The CellFX nsPFA Endocardial Ablation Catheter System includes the nsPFA 360 Endocardial Ablation Catheter, CellFX Console, switcher box/adapter, and sensing cable. The System is a proprietary endocardial catheter system designed for use in cardiac electrophysiology procedures to treat arrhythmias, including atrial fibrillation. The nano-PFA 360 Catheter ablates cardiac tissue using nonthermal nanosecond pulses of electrical energy. nsPFA is a cell-specific, nonthermal ablation technology that delivers nanosecond-duration pulses of high-amplitude electrical energy to tissue via bipolar electrodes. The pulses disrupt the cell's and internal organelles' ability to maintain cellular homeostasis by creating nanopores in lipid membranes, ultimately leading to regulated cell death (RCD).
