Available in PDF, EPUB and Kindle. Book excerpt: This book covers biodevices, mainly implantable or quirurgical, for the diagnosis or treatment of different pathologies, which benefit from the use of active materials as sensors or actuators. Such active or "intelligent" materials are capable of responding in a controlled way to different external physical or chemical stimuli by changing some of their properties. These materials can be used to design and develop sensors, actuators, and multifunctional systems with a large number of applications for developing biodevices and medical appliances. Current work on these fields entails problems related to synthesis, characterization, modeling, simulation, processing, and prototyping technologies, as well as device testing and validation, all of which are treated in depth in this book, for the several types of active or intelligent materials covered. The research presented in this book helps further development of medical devices, based on the additional functionalities that the use of active or "intelligent" materials, both as sensors and actuators, supplies. The main results exposed may help with the industrial expansion of this kind of materials as part of more complex systems.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2013-12-05 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past 2000 years, many devices have been developed and used in the mitigation and diagnosis of diseases. The materials used in these devices have ranged from stone, wood, metal, ceramics, and most recently plastics. Medical devices have also evolved in sophistication and complexity over time. With the formalization of the scientific method in the seventeenth century such devices became more prevalent [1]. Many medical devices were manufactured by doctors or small companies and sold directly to the public with no government standards or oversight. With the explosion of medical technology in the early twentieth century, several intermediaries had evolved between the medical device industry and the public. In 1879, Dr E.R. Squibb, in an address to the Medical Society of the State of New York, proposed the enactment of a national statute to regulate food and drugs [2]. It was not until 27 years later that the Food and Drug Act of 1906 was introduced into the Congress and signed into law by President Theodore Roosevelt [3]. At that time, devices that were harmful to human safety and health proliferated the market but regulation of medical devices by the Bureau of Chemistry (the precursor to the Food and Drug Administration—FDA) was limited to challenging commercial products only after they had been released into the market. Devices in the marketplace that were defective, adulterated, or misbranded were seized and the device manufacturers were prosecuted in a court of law, but only after the products were sold in the market and caused harm to the end users. Thus, there was a strong need for regulating the devices before they entered the marketplace. An FDA report [4], issued in September 1970, detailed as many as 10,000 injuries and 731 deaths from ineffective medical devices. The report recommended the formation of a regulatory system and body that would enforce the production and sale of safe and effective devices to the public. All medical devices already on the market would be inventoried and classified into a three-tiered system based on their criticality of end use. It also detailed requirements for records and reports, registration and inspection of establishments, and uniform quality assurance programs called good manufacturing practices (GMP). After much lobbying by the FDA, Senate bill SR 510, “The Medical Device Amendments of 1973” was introduced by Senator Edward M. Kennedy and was passed by the Senate in 1975. House bill HR 11124, introduced by Representative Paul Rogers, was passed by the House in 1976. These bills eventually became the Medical Device Amendments of 1976, and were signed into law by President Nixon. The Medical Device Amendments of 1976 became the basis for the medical device regulation in the United States to control and regulate the production of finished devices and thus the device manufacturers themselves.

Download or read book Handbook of Polymer Applications in Medicine and Medical Devices written by Paul Stoodley and published by Elsevier Inc. Chapters. This book was released on 2013-12-05 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: The initial design criteria in the choice of indwelling materials for medical and dental purposes may be pragmatic, and based on the necessary mechanical properties required to fashion a functional device. Orthopedic implants require strong materials for weight-bearing, and articulating surfaces such as joints require durability and resistance to wear. Stents and shunts require flexibility and patency, and sutures require a high tensile strength yet also must be flexible enough for intricate manipulation. As the devices became more sophisticated and developments in materials science provided more options for manufacture, implants are being used more frequently and with longer anticipated lifetimes. Concurrently, the design process increasingly incorporated biocompatibility and comfort into the design criteria. However, with longer lifetimes, the more frequent use of invasive surgical procedures involving indwelling devices and biologically-friendly materials, there has been a rise in the number of incidences of device-related infection. Urinary catheters have been estimated to account for 30% of all nosocomial infections [1]. Between 66 and 88% of these occur after urinary catheterization [2]. It is also reported that almost 100% of catheterized patients develop an infection in an openly draining indwelling catheter which has been in place for four days or more [2]. For some procedures, such as orthopedic joint arthroplasties, the diagnosed surgical site infection rates are relatively low (between 1% and 2%; [3]); however, the increasing number of patients undergoing joint-replacement surgery translates to large numbers of patients afflicted with the consequences of complicating infections per year. Furthermore, infection of artificial joints can be devastating, since oral or IV antibiotic therapy frequently fails to resolve the infection, with the only remaining course of action being surgical debridement or partial or total revision. These two examples, the first with very high numbers of patients but of lesser severity in terms of impact to the individual, and the second, low numbers but severe patient impact, reflect the incentive to pursue a third design criteria—that of infection resistance—into materials and devices [4]. In the following sections we will discuss the role of bacterial biofilms in infection, and the growing literature highlighting biofilms as an important cause of device-related infection.
