What is Nitinol Tube?
Nitinol, an alloy composed mainly of nickel and titanium, has revolutionized the design of medical devices, particularly in the field of cardiovascular treatment. Known for its exceptional flexibility, shape-memory characteristics, and biocompatibility, Nitinol tubing is widely used in critical medical devices such as heart pacemaker electrodes and other precision components. This advanced material offers unmatched durability and performance in demanding medical environments, ensuring both patient safety and the long-term reliability of devices.
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
One of the most remarkable features of Nitinol tubing is its ability to return to a pre-set shape when heated. This shape memory effect allows for the design of smaller, more compact pacemakers and electrodes, with the tubing easily adapting to different shapes as required by the medical device.Superelasticity
Nitinol exhibits superelasticity, meaning it can withstand large amounts of deformation without permanent damage. This makes it an ideal material for heart pacemaker electrodes, where the tubing must flex and bend without losing its structural integrity.Corrosion Resistance
Nitinol is highly resistant to corrosion, making it safe for long-term implantation in the human body. This resistance to corrosion and biological degradation ensures that medical devices maintain their functionality over extended periods, reducing the need for maintenance or replacement.Biocompatibility
Nitinol is biocompatible, meaning it is non-toxic and well-tolerated by the body. This property is crucial in medical applications, as it minimizes the risk of adverse reactions when the material is implanted in patients.Durability and Strength
Nitinol tubing is incredibly strong yet flexible. The combination of these two properties allows it to perform well under stress, making it ideal for use in heart pacemakers and other medical devices where both flexibility and strength are required.
