Pulse Field Ablation Catheters: What The Growth Means For MedTech

Written by Brittany Mai | May 8, 2025 12:00:00 AM

Pulse Field Ablation (PFA) is reshaping the landscape of cardiac ablation therapies—offering a safer, faster, and more targeted approach for treating atrial fibrillation (AFib). As clinical adoption accelerates and demand surges, medical device manufacturers are racing to keep pace. But with innovation comes complexity—especially when it comes to the critical design and manufacturing challenges of PFA catheters.

At Confluent Medical Technologies, we see this as more than just a market trend—it’s a call to action. Our expertise across Nitinol components, Complex Catheters, and high-performance Polymer Tubing uniquely positions us to support device manufacturers ready to lead in the PFA space.

Why PFA is the Future of AFib Treatment

Unlike traditional thermal ablation techniques (radiofrequency or cryoablation), PFA uses high-voltage electrical pulses to selectively ablate myocardial tissue while sparing nearby structures. This translates to improved safety profiles, faster procedures, and more consistent outcomes. However, to fully realize PFA’s potential, devices must meet higher standards for precision, flexibility, and control.

Confluent's Role in Empowering Next-Generation PFA Devices

  1. Precision-Engineered Nitinol for Ablation Accuracy

PFA catheters require intricate, geometrically precise electrode arrays to deliver pulsed fields exactly where needed. This is where Nitinol becomes a game changer. Known for its superelasticity and shape memory, Nitinol is the ideal material for forming the complex structures PFA catheters demand.

With over 30 years of unrivaled materials science expertise, Confluent leads the industry in Nitinol innovation. Our vertically integrated supply chain ensures a secure, traceable, and responsive source for this critical material—allowing us to offer the fastest lead times in the industry while maintaining exacting quality standards.

  1. Complex Catheter Design & Manufacturing

As PFA technology evolves, so does the complexity of the delivery system. Devices must navigate tortuous anatomy and deploy energy with surgical precision. Confluent’s deep experience in Complex Catheter assembly supports these demands, offering robust solutions for shaft construction, steerability, and torque response. Whether you're working on early-stage prototypes or scaling for commercialization, our engineers understand the nuances of translating clinical performance into manufacturable solutions.

  1. Advanced Polymer Tubing for Steerable Systems

The steerable sheath or guide catheter plays a critical role in PFA systems, providing control and positioning for the ablation catheter. Confluent’s polymer division is pushing the boundaries of what’s possible with PTFE and polyimide technologies. These materials offer low-friction navigation and high heat resistance, making them ideal for steerable devices. Our advanced filmcast capabilities allow for custom designs with ultra-thin walls, multi-lumen constructions, and tailored mechanical properties—perfect for today's most demanding electrophysiology applications.

A Trusted Partner in a Rapidly Evolving Market

As demand for PFA grows, so does the need for manufacturing partners who can deliver innovation without compromise. At Confluent, we combine deep technical knowledge, vertically integrated capabilities, and a collaborative approach to help medical device companies bring next-generation ablation devices to market—faster and with greater confidence.

If you’re developing a PFA catheter system and looking for a partner who understands both the science and the stakes, let’s talk. Together, we can help shape the future of electrophysiology.
