Medical Coatings and Deposition Technologies is an important new addition to the libraries of medical device designers and manufacturers. Coatings enable the properties of the surface of a device to be controlled independently from the underlying bulk properties; they are often critical to the performance of the device and their use is rapidly growing. This book provides an introduction to many of the most important types of coatings used on modern medical devices as well as descriptions of the techniques by which they are applied and methods for testing their efficacy. Developers of new medical devices and those responsible for producing them will find it an important reference when deciding if a particular functionality can be provided by a coating and what limitations may apply in a given application. Written as a practical guide and containing many specific coating examples and a large number of references for further reading, the book will also be useful to students in materials science & engineering with an interest in medical devices. Chapters on antimicrobial coatings as well as coatings for biocompatibility, drug delivery, radiopacity and hardness are supported by chapters describing key liquid coating processes, plasma-based processes and chemical vapor deposition. Many types of coatings can be applied by more than one technique and the reader will learn the tradeoffs given the relevant design, manufacturing and economic constraints. The chapter on regulatory considerations provides important perspectives regarding the marketing of these coatings and medical devices.

The Handbook of Materials for Medical Devices provides an in-depth review of the properties, processing, and selection of materials used in the environment of the human body - an environment that is surprisingly hostile and aggressive. Among the application areas described are orthopedics (hips, knees, and spinal and fracture fixation), cardiology (stents, heart valves, pacemakers), surgical instruments, and restorative dentistry. Materials discussed include metals and alloys, ceramics, glasses, and glass-ceramics, polymeric materials, composites, coatings, and adhesives and cements. The book is divided into three major sections. The first section provides an expansive overview of biomaterials and their use in medical devices. Charts and diagrams illustrate/list the many parts of the body that can be replaced by manmade materials. Case histories document some of the more common and successful medical device applications. Biocompatibility and mechanical requirements for implantable devices are also reviewed. The second section of the handbook deals with medical (nondental) applications. Stainless steels, cobalt-chromium alloys, titanium alloys, shape memory alloys, and tantalum are among the metallic materials described. Similar information is provided on nonmetallic materials, including new coatings that offer lubricity, biocompatibility, and antimicrobial action to device surfaces. Other coatings can be used to release drugs or make implanted devices more visible to imaging systems. The final section addresses biomaterials for dental applications. Emphasis is placed on corrosion and tribological behavior and corresponding test procedures to determine corrosion and wear resistance. Contents: Introduction: Overview of Biomaterials and Their use in Medical Devices; Physical and Mechanical Requirements for Medical Device Materials. Medical (Nondental) Applications: Metallic Materials; Corrosion of Metallic Implants and Prosthetic Devices; Failure Analysis of Metallic Orthopedic Implants; Ceramic Materials; Polymeric Materials; Adhesives and Cements; Coatings.

This new text provides a practical guide to hydrophilic polymer coatings technology for applications in a wide range of medical materials and devices. It concisely provides both the scientific basics of this class of polymers and the up-to-date information needed for product development and evaluation, processing, manufacturing, and regulatory compliance. More than fifty schematics illustrate materials, processes, and equipment. The entire presentation is oriented to the practical needs of personnel involved in product development and evaluation, process engineering, and manufacturing management.

In this proceedings volume, professionals from the medical device industry and their suppliers share technological and scientific knowledge, as well as insights into the latest innovations. The focus is on metallic materials, such as titanium alloys, Nitinol, cobalt-chromium alloys, stainless steels and noble metals, as applied in various medical devices. Topics range from orthopedics to orthodontics, materials selection to materials characterization. --

Based on a fundamental understanding of the interaction between bacteria and materials, this timely volume emphasizes the latest research in the antimicrobial interfacial design and provides an invaluable blueprint for improving antimicrobial performance on devices and products. Antimicrobial Coatings and Modifications targets reduction of microbial accumulation on biomedical and industrial materials through changing interfacial characteristics. Applying a viable antimicrobial coating or modification to resist alarming threats is a highly demanding requirement for many medical and engineering applications. Many contemporary books in the area of antimicrobial solution focus on applying antimicrobial agents or materials that can kill bacteria. The volume pays more attention to eliminating bacterial contamination and biofilm formation through surface characteristics with minimized bacterial resistance and environmental impact.

The Materials & Processes for Medical Devices Conference focuses on the materials science and engineering aspects of the medical devices industry. Device manufacturers, materials providers, and clinicians share information and knowledge on materials and their properties. Coverage ranges from cardiovascular devices to orthopedics to dental appliances. --
