Product Description

Product Description
Nitinol is a unique material. No other material exhibits the mechanical shape memory superelasticity and the thermal shape memory effects. This is especially true for Nitinol tubing.Fields of applications of Nitinol tubes are peripheral stents,cardio stents and other medical devices for the human body. We only deliver Nitinol tubes with the mechanical properties, requested tolerances and appropriate surface quality for stent use. All our Niti tubes are made according to customers specifications.

Nitinol tubing for medical devices
Medical devices use requires high quality surface on Nitinol tubing. The technology and tube making processes developed by Vascotube have been perfected over many years of practice. Using our experience, combined with new technologies and custom made machinery, we have been able to develop a drawing process that avoids the need for slurry cleaning, chemical cleaning or mechanical removal operations on the inner surface of the drawn tube. Our process allows us to attain a roughness value of Ra 0,1 µm.
