The objective of this book is to provide academic and industrial researchers with the most contemporary information of prosthetic devices. Extensive information is provided concerning their synthesis, chemical compositions and analogue preparations as well as their physical properties. Mechanical and processing parameters for converting the synthetic polymer into a useable prosthetic device are also provided. All of the specified information in this book is derived from the US Patent and Trademark Office and US Patent Application databases, thereby saving the reader much time searching for the relevant references. Each selected patent or patent application will be thoroughly reviewed and then summarized in a concise and easily understood format. The patent and patent application entries included in the manuscript reflect prosthetic device advances in urgently needed areas, compositional improvements, versatility improvements, and a cost/physical property analysis.
