Beschreibung

The patient driven demand for minimally invasive procedures and image guided therapies requires the development of novel instrumentation and implants. An increasing number of devices use Nitinol as the critical component. Examples of medical applications range from orthodontic archwires and endoscopic instruments
to endovascular stents and heartvalve frames.
Nitinol (a nickel-titanium shape memory alloy) undergoes a phase change in a certain temperature range associated with a significant change in the properties of the material.
As a result, the deformation characteristics of Nitinol are similar to those of natural materials, like bone and tendon.

Ziel des Seminars

The seminar will focus on key performance attributes of Nitinol. It will provide design guidelines for Nitinol components with consideration of fatigue and durability, biocompatibility and corrosion, MR compatibility as well as manufacturing aspects.
