Shape Memory Implants [Paperback]

Shape memory alloy implants or smart biomaterial have already been used in humans for 20 years in selected countries. Restrictions in the use of biomaterials in living organisms being reduced throughout the world now the use of SMA implants continue to expand in the fields of vascular and orthopaedic surgery, minimally invasive surgery and drug delivery systems. This book is to provide a state of the art of SMA implants and devices. For the first time long-term clinical experiences and techniques of SMA biocompatibility are presented.Shape memory alloy implants or smart biomaterial have already been used in humans for 20 years in selected countries.
