Pulsed field ablation (PFA) is a significant procedural advancement in electrophysiology. By minimizing collateral tissue damage, it allows for safer and more durable pulmonary vein isolation, ultimately improving outcomes for patients with atrial fibrillation. This progress introduces a new class of engineering considerations, defined by the need to safely deliver powerful, high-voltage energy pulses within a miniaturized, disposable device.
The system’s dual-component life cycle magnifies this core technical challenge. The system requires a cost-effective design for the single-use catheter alongside high durability for the reusable mating connector and cable because of repeated sterilization and mating cycles.
Resolving these competing life cycle objectives, coupled with the high-voltage challenges, requires a comprehensive, system-level strategy that considers everything from component selection to the final manufacturing process. A modular design approach utilizing a portfolio of proven components and technologies can help speed up the design phase of new PFA catheter products, enabling faster access to innovative therapies for patients.
