Lead Wire: Ultra-Fine, High-Strength Conductors for Advanced Medical Devices

Push the boundaries of medical device miniaturization without compromising on
strength or reliability. It is a high-straightness lead wire featuring an advanced
insulation coating, engineered specifically for next-generation medical applications, R&D, and automated manufacturing.


Why this is the Choice for Medical Device:-


1. Ultra-Miniaturization meets Extreme Strength
With conductor diameters as remarkably thin as 20μm to 200μm and coating thicknesses starting at just 1.5μm, It fits into the most space-constrained designs (such as catheters and micro-sensors). By utilizing advanced alloys not only AgCu
but also stainless steel and others, it achieves massive tensile strengths (up to 3000 MPa and 2400+ MPa, respectively), completely eliminating the traditional trade-off between wire thinness and durability.


2. Superior Straightness & Slipperiness for Complex Routing
Threading wires through narrow, winding lumens is a major challenge in medical device assembly. This features uniquely formulated slippery coats (such as Nylon and PFA) combined with high inherent straightness. This minimizes friction,
drastically improves assembly workability, and makes automated manufacturing a reality.


3. Agile R&D: Small Lots & Rapid Delivery
We understand that medical device development requires rapid prototyping and continuous iteration. Through our integrated production system, we offer aggressive lead times and support small lot production (MOQ starting at just 5,000m), empowering your R&D teams to move from concept to clinical trial faster.

Medical-grade stainless steel hypotubes and micro-tubing are fundamental structural components for minimally invasive catheter shafts, interventional delivery systems, and precision surgical instruments. Cold-drawn primarily from high-tensile 304, 304V, or 316L stainless steel, hypotubes provide the optimal balance between proximal pushability, kink resistance, and distal flexibility.

Key Technical Advantages of Medical Hypotubes

1:1 Torque Transmission & Pushability: Delivers high column strength and torsional rigidity, allowing clinicians to transmit axial force and rotation directly from the proximal handle to the distal tip without energy loss or buckling.

Laser-Cut Distal Flexibility: Engineered with spiral, pitch-variable, or puzzle-pattern laser cuts, allowing a rigid metallic shaft to smoothly transition into a highly flexible, trackable segment for navigating tortuous anatomy.

Ultra-Tight Tolerances: Manufactured via precision cold-drawing to maintain tight outer diameter (OD), inner diameter (ID), and wall thickness tolerances, ensuring consistent fluid flow rates and smooth passage of inner guidewires or tools.
