The emergence of PFA (Pulsed Electric Field Ablation) technology marks a new era in atrial fibrillation treatment, moving from “heat and cold” to “non-thermal ablation” and precision.
However, this shift in energy paradigms presents stringent challenges to catheter manufacturing: how to ensure insulation safety under microsecond-level instantaneous high pressure? How to maintain precise control within complex cardiac chambers? As a solution provider deeply rooted in the field of implantable medical device materials, we deeply integrate process control points into core components, using manufacturing certainty to address the uncertainty of R&D .
01 Functional Pipes
Dual protection of insulation, support, and ultra-thin precision.
PFA conduits must possess excellent insulation properties, structural stability, and dimensional accuracy to enable the safe transmission of microsecond-level high-voltage pulses.
Polyimide (PI) tubing: Utilizing a fully automated multi-coating and online monitoring system, the wall thickness tolerance is controlled within ±0.005mm. Even at an extreme wall thickness of 0.015mm, the insulation performance remains reliable. The tubing itself possesses sufficient rigidity to provide necessary radial support for the conduit, while also exhibiting excellent resistance to chemical substances.
Ultra-thin wall PET heat shrink tubing: relying on high-performance materials and precision manufacturing processes, it achieves a balance between ultra-thin wall thickness (as thin as 0.00015″) and high insulation performance, effectively eliminating the risk of leakage and breakdown under high voltage electric fields.
02 Handling Optimization
Balancing “bending performance” and “bending resistance”
Electrophysiological surgery requires catheters to have excellent torque transmission and bending response in order to achieve precise adhesion to the catheter wall.
Multi-cavity braided reinforced tube: Introducing dynamic tension compensation technology, it automatically corrects stress fluctuations in the braided yarns, completely eliminating the “snake effect” of the tube body, and achieving precise torque transmission at a 1:1 ratio.
Physical resistance reduction in the catheter lumen: Utilizing an integrated molding process, the problem of displacement under stress in the inner liner is completely solved. Even under large-angle bending, high-precision bending control is maintained, ensuring the catheter tip is accurately locked at the lesion location.
03 Assembly Efficiency Innovation
Multi-cavity PI-lined tubing accelerates mass production.
To help our customers meet the challenges of mass production, we have launched a brand-new multi-cavity lining PI tube solution.
Technological breakthrough: Overcoming the bonding stability of different materials in extremely small spaces, while ensuring excellent insulation performance, the internal cavity space is maximized (up to 1.0mm).
Customer benefits: The pre-installed liner simplifies the threading process of the micro-wires, significantly reducing assembly time; at the same time, it avoids the risk of insulation scratches caused by threading, keeping the production line yield at an extremely high level.
In response to the trend of diversified PFA end-body morphology, we flexibly combine nickel-titanium alloy precision shaping and connection technology to provide highly compatible key component support, helping innovative products to quickly move towards clinical translation.
The creation of each PFA conduit represents a pinnacle of materials science and precision manufacturing. From micron-level tolerance control to extremely stable mass production capabilities, we are not just providing parts, but delivering a proven solution.
