Drug delivery systems represent a vast area of research and development within biomaterials and medicine and the demand for sophisticated drug delivery devices continues to drive novel product development. Advanced drug delivery devices can offer significant advantages over conventional drugs and devices alone, such as increased efficiency, improved performance and convenience. The purpose of this book is to illustrate how effective drug delivery can be achieved by means other than tablets. The book will provide a thorough analysis of the fundamentals, applications and new technologies of drug-device combination products for use throughout the human body.Part one provides readers with an introduction and background to the field. Chapters in Part two discuss areas of application such as catheter based products, drug eluting stents and beads and anti-biotic loaded cements. Part three covers the development of drug device combination products with chapters on such topics as pre-clinical testing, sterilisation, patent issues and regulation of drug device combination products.With its distinguished editor and team of international contributors, Drug-device combination products: delivery technologies and applications is an invaluable reference for product development specialists, materials scientists and engineers in the biomedical industry and academia as well as those concerned with drug delivery. - Illustrates how effective drug delivery can be achieved by means other than tablets providing readers with a comprehensive introduction and background to the field - Provides a thorough analysis of the fundamentals, applications and new technologies of drug device combination products - Discusses areas of application such as catheter based products and reviews the development of drug device combination products including pre-clinical testing and sterilisation

While the safety assessment (“biocompatibility”) of medical devices has been focused on issues of local tissue tolerance (irritation, sensitization, cytotoxicity) and selected quantal effects (genotoxicity and acute lethality) since first being regulated in the late 1950s, this has changed as devices assumed a much more important role in healthcare and became more complex in both composition and in their design and operation. Add to this that devices now frequently serve as delivery systems for drugs, and that drugs may be combined with devices to improve device performance, and the problems of ensuring patient safety with devices has become significantly more complex. A part of this, requirements for ensuring safety (once based on use of previously acceptable materials – largely polymers and metals) have come to requiring determining which chemical entities are potentially released from a device into patients (and how much is released). Then an appropriate and relevant (yet also conservative) risk assessment must be performed for each identified chemical structure. The challenges inherent in meeting the current requirements are multifold, and this text seeks to identify, understand, and solve all of them. • Identify and verify the most appropriate available data. • As in most cases such data is for a different route of exposure, transform it for use in assessing exposure by the route of interest. • As the duration (and rate) of exposure to moieties released from a device are most frequently different (longer) than what available data speaks to, transformation across tissue is required. • As innate and adaptive immune responses are a central part of device/patient interaction, assessing potential risks on this basis are required. • Incorporating assessments for special populations such as neonates. • Use of (Q)SAR (Quantitative Structure Activity Relationships) modeling in assessments. • Performance and presentation of integrative assessments covering all potential biologic risks. Appendices will contain summarized available biocompatibility data for commonly used device materials (polymers and metals) and safety assessments on the frequently seen moieties in extractions from devices.

All biomaterials and medical devices are subject to a long list of regulatory practises and policies which must be adhered to in order to receive clearance. This book provides readers with information on the systems in place in the USA and the rest of the world. Chapters focus on a series of procedures and policies including topics such as commercialization, clinical development, general good practise manufacturing and post market surveillance. - Addresses global regulations and regulatory issues surrounding biomaterials and medical devices - Especially useful for smaller companies who may not employ a full time vigilance professional - Focuses on procedures and policies including risk management, intellectual protection, marketing authorisation, university patent licenses and general good practise manufacturing

Biocompatibility and Performance of Medical Devices, Second Edition, provides an understanding of the biocompatibility and performance tests for ensuring that biomaterials and medical devices are safe and will perform as expected in the biological environment. Sections cover key concepts and challenges faced in relation to biocompatibility in medical devices, discuss the evaluation and characterization of biocompatibility in medical devices, describe preclinical performance studies for bone, dental and soft tissue implants, and provide information on the regulation of medical devices in the European Union, Japan and China. The book concludes with a review of histopathology principles for biocompatibility and performance studies. - Presents diverse insights from experts in government, industry and academia - Delivers a comprehensive overview of testing and interpreting medical device performance - Expanded to include new information, including sections on managing extractables, accelerating and simplifying medical device development through screening and alternative biocompatibility methods, and quality strategies which fasten device access to market

Capturing the growth of the global medical device market in recent years, this practical new guide is essential for all who are responsible for ensuring safety in the use and manufacture of medical devices. It has been extensively updated to reflect significant advances, incorporating combination products and helpful case examples of current real-l

are then selected and must meet the general 'biocompatibility' require ments. Prototypes are built and tested to include biocompatibility evalua tions based on ASTM standard procedures. The device is validated for sterility and freedom from pyrogens before it can be tested on animals or humans. Medical devices are classified as class I, II or III depending on their invasiveness. Class I devices can be marketed by submitting notification to the FDA. Class II and III devices require either that they show equivalence to a device marketed prior to 1976 or that they receive pre-marketing approval. The time from device conception to FDA approval can range from months (class I device) to in excess of ten years (class III device). Therefore, much planning is necessary to pick the best regulatory approach. 2. Wound Dressings and Skin Replacement 2.1 Introduction Wounds to the skin are encountered every day. Minor skin wounds cause some pain, but these wounds will heal by themselves in time. Even though many minor wounds heal effectively without scarring in the absence of treatment, they heal more rapidly if they are kept clean and moist. Devices such as Band-Aids are used to assist in wound healing. For deeper wounds, a variety of wound dressings have been developed including cell cultured artificial skin. These materials are intended to promote healing of skin damaged or removed as a result of skin grafting, ulceration, burns, cancer excision or mechanical trauma.
