Core Engineering Advantages
Exceptional Superelasticity & Shape Recovery
Delivers consistent radial force for self-expanding implants, enabling full collapse for delivery and perfect deployment.
Pristine Oxide-Free Surface Quality
Superior cleanliness eliminates microscopic stress concentrators, drastically improving downstream laser-cutting yields.
Ultra-Precise Concentricity Control
Advanced drawing techniques ensure a tight wall thickness ratio, eliminating wall variations and ensuring balanced torque transmission.
Applications
- Laser-cut self-expanding peripheral vascular and neurovascular stents
- Embolic protection devices, baskets, and vena cava filters
- Transcatheter heart valve frames and structural delivery components
- Endoscopic retrieval clamps, biopsy forceps, and steerable arthroscopic shanks
