Shape-setting refers to the process used to form a Nitinol wire, tube or sheet into a specific and often complex geometry. Whether the Nitinol alloy is to be used in the superelastic or shape memory condition, it is necessary to establish the appropriate heat treatment. This is done by carefully constraining the material into its new shape using a specially designed fixture or mandrel followed by a defined heat treatment. Multiple shaping operations may be necessary if the part is particularly complex or to prevent cracking/fracture of high strain regions.

Memry’s in house Nitinol laser technologies are ideal for manufacturing intricate, finely structured medical devices. Memry lasers cut a full spectrum of components ranging from Neurology devices through Structural Heart Valves. Memry uses state-of-the-art high powered lasers for precision cutting of medical device Nitinol components from prototype to high volume production. Our dedicated laser team and technologies are at the forefront of many future innovations. The non-contact, high precision aspects of the technology are well suited for welding, cutting and marking. Memry adapts each laser processing platform specific to the individual part demands.

Surface finishing is critical in the manufacturing of medical devices, especially for long-term implantable products where characteristics such as corrosion resistance and fatigue life are essential. At Memry we’ve mastered surface finishing through consideration of the interactions of upstream processes. The finishes that we develop are unique to each application and are optimized to fulfill our customer’s design requirements.

Grinding is an effective way to machine complex features in Nitinol components. Memry is capable of grinding geometries ranging from simple guidewires to sophisticated grinds for any custom application, including flats, radii, drill points, trocars, needles, or thread-like profiles. Due to its titanium oxide surface, Nitinol is a tough, abrasive material, making carbide tooling a best practice.
