Tradi tionally, the International lTV - Conferences on Biomate rials are focussing on problems in Biomedical Engineering, problems, which are still unsolved, of main interest, and which are of interdisciplinary character. In 1983, the Division of Biomedical Engineering of the Institute of Textile Technology and Chemical Engineering, Denkendorf, started wi th a conference about the use of polyurethanes in biomedicine. Three years later,. in 1986, progress in development and use of polyurethanes was selected as conference topic. It had to be realized that degradation problems were still dominating the discussions. The main discussion topics were: What are the causes for the degradation? How can one prevent them? What are the degradation products, and do they affect the human body? How can one simu late the degradation? How can one accelerate the in vitro tests and how can the results predict the in vivo behaviour of the material? How do in vitro tests correlate with animal tests and the behaviour in the human body? At the third conference in 1989, the speakers focused on the use of textiles in medicine. Again the problem of degradation was discussed intensively and demonstrated by the failure of textile implants, the degradation of aramide polymers or the degradation of resorbable suture materials. The examples make clear, that degradation may be a desired or undesired property of an implant.

This book reviews the current understanding of the mechanical, chemical and biological processes that are responsible for the degradation of a variety of implant materials. All 18 chapters will be written by internationally renowned experts to address both fundamental and practical aspects of research into the field. Different failure mechanisms such as corrosion, fatigue, and wear will be reviewed, together with experimental techniques for monitoring them, either in vitro or in vivo. Procedures for implant retrieval and analysis will be presented. A variety of biomaterials (stainless steels, titanium and its alloys, nitinol, magnesium alloys, polyethylene, biodegradable polymers, silicone gel, hydrogels, calcium phosphates) and medical devices (orthopedic and dental implants, stents, heart valves, breast implants) will be analyzed in detail.

Bioresorbable materials are extensively used for a wide range of biomedical applications from drug delivery to fracture fixation, and may remain in the body for weeks, months or even years. Accurately predicting and evaluating the degradation rate of these materials is critical to their performance and the controlled release of bioactive agents. Degradation rate of bioresorbable materials provides a comprehensive review of the most important techniques in safely predicting and evaluating the degradation rate of polymer, ceramic and composite based biomaterials. Part one provides an introductory review of bioresorbable materials and the biological environment of the body. Chapters in Part two address degradation mechanisms of commonly used materials such as polymers and ceramics. This is followed by chapters on bioresorption test methods and modelling techniques in Part three. Part four discusses factors influencing bioresorbability such as sterilisation, porosity and host response. The final section reviews current clinical applications of bioresorbable materials. With its distinguished editor and multidisciplinary team of international contributors, Degradation rate of bioresorbable materials: prediction and evaluation provides a unique and valuable reference for biomaterials scientists, engineers and students as well as the medical community. Comprehensively reviews the most pertinent techniques in safely predicting and evaluating the degradation rate of bioresorbable materials Addresses degradation mechanisms of commonly used materials Discusses factors influencing bioresorbability such as sterilisation and host response

This book in the emerging research field of biomaterials covers biodegradable metals for biomedical applications. The book contains two main parts where each of them consists of three chapters. The first part introduces the readers to the field of metallic biomaterials, exposes the state of the art of biodegradable metals, and reveals its application for cardiovascular implants. Some fundamental aspects to give basic understanding on metals for further review on the degradable ones is covered in chapter one. The second chapter introduces the concept of biodegradable metals, it's state of the art and discuses a shifted paradigm from inert to bioactive, from corrosion resistant to corrodible metals. The third chapter focuses on the challenges and opportunities of using biodegradable metals for cardiovascular applications. The second part exposes an example of biodegradable metals from its concept to applications where a complete study on metallic biodegradable stent is detailed from materials design, development, testing till the implant fabrication. The forth chapter reveals new alloys development devoted for metallic biodegradable stent based on required criteria derrived from clinical needs and current nondegradable stents properties. Degradation of the alloys in simulated arterial conditions and its effect to cells are exposed in chapter five. The both chapters are concluded with a benchmarking of some more recent researches on materials development and testing for biodegradable stents. Chapter six reveals the tranformation process of the materials into stent prototypes where a standard process for making 316L stainless steel stents was followed. The book is completed by a perspective on the use of biodegradable metals for biomedical applications in the era of tissue engineering.

This book presents a generalised computational model for the degradation of resorbable composites, using analytic expressions to represent the interwoven phenomena present during degradation. It then combines this modelling framework with a comprehensive database of quantitative degradation data mined from existing literature and from novel experiments, to provide new insights into the interrelated factors controlling degradation. Resorbable composites made of biodegradable polyesters and calcium-based ceramics have significant therapeutic potential as tissue engineering scaffolds, as temporary implants and as drug-loaded matrices for controlled release. However, their degradation is complex and the rate of resorption depends on multiple connected factors such as the shape and size of the device, polymer chemistry and molecular weight, particle phase, size, volume fraction, distribution and pH-dependent dissolution properties. Understanding and ultimately predicting the degradation of resorbable composites is of central importance if we are to fully unlock the promise of these materials.
