Wave pattern background for FARAPULSE PFA system

About PFA therapy

Non-thermal mechanism of action for cardiac ablation

Unlike thermal cardiac ablation methods, pulsed field ablation (PFA) therapy uses short bursts of electrical pulses to treat atrial fibrillation (AFib). The goal of PFA therapy is to isolate and target specific characteristics of cardiac tissue for irreversible electroporation (IRE), inducing cell death and durable lesions using a non-thermal energy source.


Optimized catheter design for pulmonary vein isolation (PVI)

The 5-spline FARAWAVE™ Pulsed Field Ablation Catheter is the optimal shape to achieve catheter placement in a range of pulmonary vein (PV) anatomies and address PFA energy delivery needs. No other design test demonstrated the same maneuverability, variable distal shape tips or circumference ablation capabilities, all without the need to manually manage electrode activation.

Prioritizing efficacy while
minimizing unwanted artifacts

Optimizing PFA delivery involves numerous elements of catheter and waveform design in order to create a field of effect for irreversible electroporation (IRE) without causing unwanted artifacts. The extensive FARAWAVE PFA Catheter development timeline in both the pre-clinical and clinical stages drove to balance these factors into the waveform that has now been used in so many patients across the globe.

Proven 8-application workflow 

The FARAPULSE dosing protocol is simple yet effective in delivering durable lesions across the PV antrum and ostium. Each vein is preferentially ablated via eight 2.5-second applications utilizing both distal shapes in a prescribed series.
