Medical Multi-Layer Multi-Strand Traction Wire

Solution

Product Description

The most typical application of coil is to drive intravascular ultrasound imaging (IVUS) and intravascular optical coherence tomography (OCT). Since imaging completely relies on the rotation and retraction of the imaging probe in the blood vessel to achieve a complete scan of the blood vessel, the stability of movement, repeatability, and precise transmission of driving torque directly affect the image quality. Especially now that the resolution, accuracy, and speed of intravascular imaging methods have been greatly improved, higher and higher requirements have been placed on the transmission and motion performance of coils. Therefore, as a key component of intravascular imaging, coils also need to be continuously developed and improved.

1. SUS304, SUS304V, SUS316, PTFE coated guidewires.

2. Four-strand, eight-strand, twelve-strand, eighteen-strand single-layer/double-layer guidewires.

3. Excellent torsion and maneuverability.

4. Strong bending ability, easy to pass through tortuous and restricted areas.

The Medical Multi-Layer Multi-Strand Traction Wire is a high-performance, finely braided cable designed for demanding medical applications. It features a multi-layer construction of ultra-fine strands, providing exceptional tensile strength, superior flexibility, and minimal elongation under load. This design ensures precise force transmission and reliable performance in critical devices like orthopedic systems and surgical robotics. Its corrosion-resistant and biocompatible coating makes it ideal for long-term implantable and sterile environments.

Product Features

Medical Multi-Layer Multi-Strand Traction Wires represent a significant advancement in surgical and interventional device technology. Engineered with a multi-layer architecture, these wires typically feature a core of 7 strands, surrounded by an intermediate layer of 12 strands, and an outer layer of 18 strands, creating a high-strand-count cable (e.g., 7x7x18 construction) for exceptional flexibility and kink resistance, with a minimum bend radius of less than 1 mm. This complex construction provides superior tensile strength, often exceeding 2,000 MPa, ensuring reliable performance under high loads. The wires are manufactured from high-grade austenitic stainless steel (e.g., 304V or 316LVM), offering excellent corrosion resistance and biocompatibility per ISO 10993 standards. Furthermore, they exhibit minimal elongation under load, typically less than 1.5%, ensuring precise force transmission and control. Finally, the surface is often finished with a proprietary low-friction coating (e.g., PTFE), reducing the coefficient of friction to below 0.1 for smooth navigation through complex anatomical pathways and catheter lumens.
