Nickel Titanium, commonly known as Nitinol, is a metal alloy of nickel and titanium that has incredibly useful properties for medical devices. Nitinol can deform 10-30 times as much as ordinary metals, and still return to its original shape, allowing for various therapeutic applications.

At Midwest Interventional Systems, we help with the development of your nitinol components and devices. Our experience spans machine braided, hand braided, and shape set nitinol stents, baskets, snares, and catheter components.

Learn more about our nitinol operations below...

Machine Braided

Machine braided nitinol can be used for implantable medical devices and allows us to create accurate and repeatable structures, with advanced braid configurations for the most specific application needs.

Shape Set

Shape set nitinol is achieved by constraining the material in a fixture of the desired shape and size and applying an appropriate heat treatment followed by rapid cooling via air or water. Shape setting allows for reliably reproducible components that take advantage of nitinol's shape memory properties.

Take full advantage of nitinol with our rapid in-house prototyping capabilities.
