What is Nitinol Tube?
Nitinol, an advanced nickel-titanium alloy, is revolutionizing the field of cardiovascular stents and heart implant technologies. Known for its exceptional shape memory effect, biocompatibility, and durability, Nitinol is increasingly used to create innovative cardiovascular devices, such as stents, heart valves, and other implants. Its ability to expand and contract according to temperature changes makes it the ideal material for these critical applications, ensuring a perfect fit and optimal performance in patients’ cardiovascular systems.
At Victory Supplier, we provide high-quality Nitinol tubing and components designed specifically for cardiovascular stents and other heart implant technologies. Whether you're developing a new type of stent, valve, or catheter, our Nitinol solutions deliver the reliability and precision needed for advanced cardiovascular care.
Tubing Actual Performance Af Temperature | For finished tubes with an outer diameter of 0.25-9.0mm, after cutting a section of the tube, the actual recovery temperature can be tested using the bending recovery method specified in ASTM F2082/F2082M-16. |
| Surface Condition | Outer Surface: Oxidized state, ground state Inner Surface: Clean state |
| Tubing Length | Length can be precisely specified or arbitrarily specified; for arbitrary lengths, the maximum and minimum lengths can be negotiated with sales or technical personnel. |
| Straightness | The requirements and test methods for straightness can be agreed upon with sales or technical personnel. |
| Internal and External Surface Defects | The requirements for surface defects can be agreed upon with sales or technical personnel. |
| Typical Applications | Medical: Hypo tubes, camera tubes, stents, baskets, catheters |
Features of Nitinol Tube
Shape Memory Effect: Nitinol’s most distinctive property is its shape memory effect. When exposed to body temperature, Nitinol stents and heart implants expand or contract to their predetermined shape, making it an ideal material for self-expanding stents that conform perfectly to the blood vessel walls.
Superior Biocompatibility: Nitinol is highly biocompatible, meaning it’s well-tolerated by the human body, reducing the risk of immune reactions or rejection. This is critical for implants like stents that need to remain in the body for long periods without causing adverse effects.
High Strength and Flexibility: Nitinol combines strength and flexibility in ways that other metals cannot. This makes it highly durable while also allowing for flexibility during implantation. Cardiovascular devices like stents need to withstand the dynamic pressures of the bloodstream while retaining flexibility during insertion—Nitinol meets both these needs.
Fatigue Resistance: Unlike traditional materials, Nitinol can endure repeated cycles of deformation without compromising its integrity, which is vital for devices like vascular stents that experience continuous mechanical stress within the body.
Corrosion Resistance: Nitinol exhibits exceptional resistance to corrosion from bodily fluids, ensuring the long-term stability of implants like stents, heart valves, and other cardiac devices. This is particularly important for minimizing the risk of device failure over time.

Advantages of Nitinol Tube
Self-Expanding Stents: Nitinol’s ability to return to a predefined shape makes it perfect for self-expanding stents. As these stents are introduced into the body, they automatically expand to match the vessel size, ensuring proper blood flow without the need for balloon inflation, thus simplifying the procedure.
Improved Patient Safety: The biocompatibility of Nitinol reduces the chances of inflammation, blood clots, or rejection, ensuring a safer long-term implant experience. Its ability to resist corrosion also lowers the likelihood of complications caused by metal degradation inside the body.
Minimized Trauma: Nitinol’s flexibility allows for minimally invasive procedures. It can be delivered via smaller, more flexible catheters, reducing the need for large incisions and speeding up recovery time for patients.
Durable and Reliable Performance: Nitinol stents and heart implants have a high fatigue resistance, meaning they maintain their shape and strength even after being subjected to repeated compressive forces. This ensures consistent, long-term performance within the body.
Tailored Designs: The flexibility and customizable nature of Nitinol allow for personalized cardiovascular solutions. Devices can be engineered to meet specific anatomical requirements, ensuring a perfect fit for patients with different vessel sizes and conditions.
Applications of Nitinol Tube
Cardiovascular Stents: The self-expanding nature of Nitinol makes it an ideal material for vascular stents that help keep arteries open and restore proper blood flow. These stents are commonly used in the treatment of coronary artery disease (CAD) and peripheral artery disease (PAD).
Heart Valves: Nitinol is also utilized in the creation of heart valve replacements, where its shape memory effect allows the valve to return to its optimal position and function after deployment, providing stability and flexibility in dynamic cardiac environments.
Catheters and Guidewires: Nitinol is used in the production of catheters and guidewires for cardiovascular procedures. Its flexibility and strength make it ideal for navigating through the complex anatomy of blood vessels and delivering stents or other devices with precision.
Aneurysm Stents: For treating aneurysms, Nitinol’s resilience and flexibility help create endovascular aneurysm repair (EVAR) stents that conform precisely to the shape of the blood vessel, offering enhanced protection and support.
Coronary and Peripheral Stents: Nitinol’s versatility makes it suitable for both coronary stents used to treat coronary artery disease and peripheral stents for treating diseases affecting the arteries outside the heart, including those in the legs or kidneys.
