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.

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.
