NiTi (Nickel-Titanium Alloy)
NiTi, also known as Nitinol, is a shape memory alloy composed of roughly equal parts of nickel and titanium. Its unique properties include:
- Shape Memory Effect: The ability to return to a pre-defined shape when heated.
- Superelasticity: High elasticity, allowing the material to undergo significant deformation and recover without permanent damage.
- Corrosion Resistance: Excellent resistance to corrosion, particularly in biological and marine environments.
- التوافق الحيوي: Commonly used in medical applications such as stents, orthodontic wires, and surgical tools.
These properties make NiTi widely used in medical devices, aerospace, robotics, and industrial applications.
L605 (Cobalt-Chromium Alloy)
L605, also known as Haynes 25 or Alloy 25, is a cobalt-chromium-tungsten-nickel alloy recognized for its exceptional strength and resistance to high temperatures. Key characteristics include:
- High-Temperature Resistance: Excellent performance in environments up to 1093°C (2000°F).
- Wear and Corrosion Resistance: Outstanding resistance to oxidation, scaling, and various forms of corrosion.
- التوافق الحيوي: Suitable for use in medical implants, including heart valves and surgical components.
- Durability: High strength and resistance to mechanical fatigue.
L605 is commonly used in the aerospace industry, gas turbines, and medical applications due to its excellent mechanical and chemical properties.
Application of NiTi & L605 Valve Stent
1. Cardiology (Heart Valves):
The stent is used to support and restore the functionality of heart valves, such as the aortic or mitral valve. Its flexibility allows it to adapt to the patient’s anatomy, while its high strength ensures long-term durability.
2. Minimally Invasive Procedures:
- Utilized in transcatheter procedures for valve replacement or repair (e.g., TAVR/TAVI – Transcatheter Aortic Valve Replacement).
- Eliminates the need for open-heart surgery.
3. Biocompatibility and Durability:
- The combination of NiTi and L605 materials ensures resistance to corrosion and biological degradation, making the stent safe for long-term implantation.
- The materials are biocompatible, minimizing the risk of rejection and ensuring sustained performance.
4. Ease of Implantation:
- The flexibility and shape-memory properties of NiTi make the stent easy to compress for catheter delivery and expand to the desired size at the implantation site.
- Superelasticity aids in precise positioning and deployment.
5. Restoration of Valve Function:
- Reinforces valve walls, restoring their ability to regulate normal blood flow.
- Used in patients with valve insufficiency or stenosis.
This stent is particularly beneficial for elderly patients or those with contraindications for open-heart surgery, offering a safe and effective alternative for valve repair or replacement.
