- Company: Cardiovalve (now part of Edwards Lifesciences) developed a nitinol-frame transcatheter valve.

2. Shape-Memory Stents for Peripheral Artery Disease (2024)
- Innovation: Next-gen nitinol stents that resist kinking and collapse in leg arteries, improving long-term patency.
- Study:
- [Journal of Endovascular Therapy(2024): "Nitinol Stents with Enhanced Fatigue Resistance"]
- Company: Boston Scientific's Eluvia® stent (uses nitinol + drug coating).

3. Smart Orthodontic Archwires (2024)
- Advancement: Temperature-responsive nitinol wires that apply dynamic forces, reducing treatment time by 30%.
- Research:
- [Science Advances: "AI-optimized nitinol wires for personalized orthodontics" (Jan 2024)]
- Developer: Ormco(a dental tech company) launched "HyperByte" with nitinol tech.

4. Biodegradable Nitinol for Pediatric Implants (2023)
- Breakthrough: Experimental **nitinol with biodegradable coatings for pediatric cardiac implants, avoiding removal surgeries.
- Source:

- Team: MIT/Harvard researchers.

5. Neuromodulation Devices (2024)
- Application: Nitinol-based **nerve cuffs** that self-wrap around nerves for precise stimulation 
- News:
- [*IEEE Spectrum: "Shape-Memory Neural Interfaces" (Mar 2024)]
- Developer: NeuroNexus (prototype phase).

Key Challenges & Future Trends
- Fatigue Resistance: New alloys (e.g., NiTiCr) to extend implant lifespan (Advanced Materials, 2024).
- 3D Printing: Custom nitinol implants via additive manufacturing ([3DPrintingIndustry, 2023]
