Design Engineering of Nitinol based Medical Devices

Design Engineering of Nitinol based Medical Devices

Abstract

The usage of Shapememory alloy (SMA) has exploded in last two decades. NiTi SMA Alloy (Nitinol) has been applied in many industry for example in military, safety, robotics and aerospace especially in medical industry. Because of unique properties of Nitinol, it changed the traditional open-surgical techniques to less-invasive techniques. Nitinol's unique property is used in designing the medical devices and instruments for critical applications. Finite Element Analysis (FEA) approach is used to reduce the design validation time in product life cycle of the Medical product. The unique properties and applications of Nitinol in medical industry and role of Finite Element Analysis in designing medical devices are discussed. This material is worth reading for Medical device designers, Stress Analyst, Material scientist and R&D Managers.

Excerpts from the Paper

Nitinol has become a key material to design medical devices and instruments. The special characteristics of Nitinol are emphasized by describing the following applications of Nitinol in medical industry. Today, most self-expanding implants such as stents and filters use the thermal shape-memory of Nitinol to enable deployment into the body. One of the current largest applications of Nitinol is for intravascular stents. Stent is a flexible tubular structure capable of being folded into small dimensions allowing its passage into the problematic locations in the body and then being expanded. Stents are used to treat narrowed or weakened coronary arteries in the body. The blockage in blood flow is treated by expanding the stent to enlarge diameter of the arteries. Self expanding stent uses the thermal shape memory of Nitinol to enable deployment into the body.
