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.
