Nickel-Titanium Tubing with Superelasticity and High Precision

Nickel-titanium tubing, with its unique properties and wide range of applications, is driving innovation and development of medical device technology. The AccuPath® nickel-titanium tubing can meet the design requirements of large angle deformation and alien fixed release, thanks to the hyperelasticity and shape memory effect. Its constant tension and resistance to kink reduce the risk of fracture, bending or injury to the human body. Secondly, Nickel-titanium tubing have excellent biocompatibility and can be safely used in humans, whether for short-term use or long-term implants. AccuPath® can customize tubing of different sizes and shapes to meet the needs of different application scenarios.
