Memry has been drawing tube since 1992. We can quickly deliver nitinol tube with a variety of finishes and in a wide range of sizes. That includes the very small, such as hypotubes, which are growing in demand among designers of advanced interventional products.
The company’s state-of-the-art process makes for tubing with optimal flexibility, kink-resistance, a low permanent set and high loading/unloading plateau stresses between 15ºC and 50ºC.
Nitinol was first used to create devices like needles, specialty guidewires and delivery system products that required low-profile, flexible shafts with consistent column strength. To service the most demanding applications, Memry has steadily increased the sophistication with which it can draw and process nitinol tube.
A proven track record + an innovative approach
The engineering team has established itself in recent years by supplying customized nitinol tubing for a number of devices that are now on the market. We are also providing tubing for a range of next-generation devices currently under design.
Our tubing specifications below are proven reference points, not design limits. We are always eager to discuss specifications for new applications.
Nitinol is also available in a new alloy, Redox™.
