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.
