PFA

What Core Components Lie Behind the Birth of Every PFA Catheter?

The emergence of Pulsed Field Ablation (PFA) technology marks the transition of atrial fibrillation treatment from the era of “heat and cold” to the precise age of “non-thermal ablation.”

However, this shift in energy paradigms poses stringent challenges to catheter manufacturing: How to ensure insulation safety under microsecond-level instantaneous high voltage? How to maintain precise maneuverability within complex cardiac chambers? As a solution provider deeply rooted in the field of materials for implantable and interventional medical devices, we integrate process control points deeply into core components, countering the uncertainties of R&D with the certainty of manufacturing.

01 Functional Tubing

Dual Guardianship of Insulation, Support, and Ultra-thin Precision

PFA catheters require excellent insulation performance, structural stability, and dimensional accuracy to achieve the safe transmission of microsecond-level high-voltage pulses.

02 Maneuverability Optimization

Balancing “Deflection Performance” and “Kink Resistance”

Electrophysiology procedures demand catheters with excellent torque transmission and deflection response to achieve precise tissue contact.

• Multi-lumen Braid-reinforced Tubing:

Dynamic tension compensation technology is introduced to automatically correct stress fluctuations in the braiding wires, completely eliminating the “snake effect” of the tubing and achieving precise 1:1 torque transmission.

• Physical Drag Reduction for Pull-wire Lumens:

Utilizing an integrated molding process to completely solve the problem of inner liner displacement under stress. Even under large-angle deflection, high-precision deflection control is maintained, ensuring the catheter tip can be accurately locked onto the lesion site.

03 Assembly Efficiency Innovation

Multi-lumen Inner-liner Polyimide Tubing: Accelerating Mass Production

To assist customers in addressing mass production challenges, we have launched a brand-new multi-lumen inner-liner Polyimide tubing solution.

• Process Breakthrough:

Overcame the challenge of bonding stability between different materials in extremely small spaces. While ensuring excellent insulation performance, it maximizes the inner lumen space (up to 1.0mm).

• Customer Benefits:

Pre-installed inner liners directly simplify the wire threading steps, significantly shortening assembly time; meanwhile, it avoids the risk of insulation jacket scratches caused by wire threading, locking production line yield at an extremely high level.

Facing the trend of diversified PFA tip morphologies, we flexibly combine Nitinol precision shaping​ with connection technologies to provide highly compatible key component support, facilitating the rapid clinical translation of innovative products.

The birth of each PFA catheter is an ultimate game between material science and precision manufacturing. From micrometer-level tolerance control to extremely stable mass delivery capabilities, we are not just providing parts, but outputting a set of proven solutions.
