Applications Of Polyurethanes In Medical Devices

Applications of Polyurethanes in Medical Devices provides detailed coverage of polyurethane (PU) chemistry, processing and preparation for performant medical devices. Polyurethanes have found many uses in medical applications, due to their biocompatibility, biostability, physical properties, surface polarity, and the ability to suit the field of application. This book enables the reader to understand polyurethane and how this valuable material can be used in medical devices. Sections cover the chemistry, structure, and properties of polyurethane, with in-depth sections examining raw materials, reaction chemistry, synthesis techniques, reaction kinetics, material microstructure, and structure-property relationships. Subsequent chapters demonstrate how polyurethane can be utilized in medical device applications, examining biological properties, rheology and processing before methodical coverage explains how polyurethane may be used for each category of medical device. Finally, future directions, and safety and environmental aspects, are covered. Bridges the gap between polyurethane chemistry, processing and preparation for cutting-edge medical device applications Includes in-depth coverage of polyurethane, covering raw materials, chemistry, synthesis techniques, reaction kinetics, properties and microstructural analysis Takes a valuable and practical approach, addressing manufacturing issues and using testing and modeling to solve problems encountered in processing

Polyurethanes in Biomedical Applications studies the use of polyurethanes in implanted medical devices. This analysis describes the concepts of polymer science, the manufacture of polyurethanes, and the biological responses to implant polyurethanes, reflecting the developments in biomaterials science and the interdisciplinary nature of bioengineering.

No book has been published that gives a detailed description of all the types of plastic materials used in medical devices, the unique requirements that the materials need to comply with and the ways standard plastics can be modified to meet such needs. This book will start with an introduction to medical devices, their classification and some of the regulations (both US and global) that affect their design, production and sale. A couple of chapters will focus on all the requirements that plastics need to meet for medical device applications. The subsequent chapters describe the various types of plastic materials, their properties profiles, the advantages and disadvantages for medical device applications, the techniques by which their properties can be enhanced, and real-world examples of their use. Comparative tables will allow readers to find the right classes of materials suitable for their applications or new product development needs.

Hydrophilic polyurethanes have the unique property of being able to absorb or otherwise manage moisture-and this makes them valuable in medical and a number of other important commercial applications. This new book provides a concise, unified presentation of hydrophilic polyurethanes technology and applications. All important topics from chemistry, analysis, processing and quality systems to product development and applications are covered clearly and systematically. The text is well illustrated by more than 45 flowcharts and diagrams and supplemented by more than 20 data tables. A special feature of this new book is its inclusion of case studies of recent development of commercially valuable products using hydrophilic polyurethanes. These case studies illustrate how these unique materials can be tailored to specific application needs. The information in this new book will be useful to all those involved in the research, development and applications of polymers, biomaterials, and other materials whose utility requires the special properties of hydrophilic polyurethanes.

Biomaterials: From Molecules to Engineered Tissue gives examples of the application areas of biomaterials involving molecules at one end of the spectrum and finished devices in the other. It covers molecular approaches as well as molecules functional in preparing and modifying biomaterials, medical devices and systems, tissue engineering and artificial organs. Chapters on biomedical informatics and ethics complement the design and production aspects with their contribution in informatics and ethical concerns of biomedical research. This is a reference book for the advanced graduate student eager to learn the biomaterials area and for all researchers working in medicine, pharmacy, engineering and basic sciences in universities, hospitals, and industry involved in biomaterials and biomedical device production.

The design and development of tissue-engineered products has benefited from many years of clinical utilization of a wide range of biodegradable polymers. Newly developed biodegradable polymers and modifications of previously developed biodegradable polymers have enhanced the tools available for creating clinically important tissue-engineering applications. Insights gained from studies of cell-matrix interactions, cell-cell signaling, and organization of cellular components, are placing increased demands on medical implants to interact with the patient’s tissue in a more biologically appropriate fashion. Whereas in the twentieth century biocompatibility was largely equated with eliciting no harmful response, the biomaterials of the twenty first century will have to elicit tissue responses that support healing or regeneration of the patient’s own tissue. This chapter surveys the universe of those biodegradable polymers that may be useful in the development of medical implants and tissue-engineered products. Here, we distinguish between biologically derived polymers and synthetic polymers. The materials are described in terms of their chemical composition, breakdown products, mechanism of breakdown, mechanical properties, and clinical limitations. Also discussed are product design considerations in processing of biomaterials into a final form (e.g., gel, membrane, matrix) that will effect the desired tissue response.
