Nitinol Round Wire VIM-VAR Superelastic Strand for Cardiovascular Guidewire & Neurovascular Capture Baskets

1. Product Description

Formulated via double vacuum remelting and multi-pass precision cold drawing, this medical-grade nitinol round wire adheres strictly to ASTM F2063-18 impurity thresholds to eliminate irritant elements that trigger vascular inflammation. Tunable Af transformation points between 10°C and 30°C enable full shape recovery under human body temperature, delivering sustained radial support for self-expanding braided interventional components. Ultra-smooth electropolished surfaces lower friction during catheter navigation inside narrow blood vessels, while ultra-low permanent deformation after repeated bending ensures stable performance for long-duration minimally invasive procedures. Tight diameter tolerances from 0.013mm up to 4.0mm match micro guidewire filaments and thick retrieval basket frames for global clinical device R&D teams.

3.Advantage

Low-inclusion vacuum smelting delivers millions of cyclic bending endurance without crack risks for permanent interventional implants
Body-temperature matched Af grades realize automatic expansion once delivered to target lesion via micro catheter channels
Burr-free polished surface drastically reduces scratch risk on fragile arterial and neurovascular walls during navigation
Graded plateau stress outputs adjustable soft/strong pushing force to fit coronary, cerebral and urinary intervention scenarios
Ultra-fine micro wire specifications support ultra-miniature devices for low-trauma minimally invasive treatment plans

4. Application

This nitinol round wire acts as core raw strand for cardiovascular guidewire cores, cerebral aneurysm capture snares, biliary stone retrieval baskets, ureteral stent braids and peripheral vascular intervention frames. It is widely selected by interventional medical device labs across North America, Europe and the Middle East for developing Class II/III disposable and permanent surgical implants used in cath labs and endoscopy centers worldwide.

5. FAQ

Q1: Why select 10–30℃ Af nitinol round wire for vascular braided stents?

A: Such grades fully restore preset expansion shape under human 37℃ body heat, providing continuous radial support without excessive mechanical stimulation to vessel walls.

Q2: Which surface finish is mandatory for permanent intracranial implant wire?

A: Ultra-gloss centerless ground finish forms dense inert titanium oxide film to block metal ion leakage and prevent tissue adhesion.

Q3: Does this wire withstand repeated torque rotation during guidewire steering?

A: Balanced torsional elasticity achieves 1:1 torque transmission without kinking inside twisted vascular pathways.

Q4: What testing protocols govern this wire’s mechanical performance for surgery?

A: All tensile, fatigue and permanent set tests are completed at constant 22°C lab temperature following ASTM F2516-18 medical alloy standards.
