Download or read book Characterization of Biomaterials written by Ming H. Wu and published by Elsevier Inc. Chapters. This book was released on 2013-03-12 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cardiovascular system consists of the heart and the vasculature. The physiology of the system is to circulate blood through the vasculature ensuring delivery of oxygen and vital nutrients to cells and organs in the body. Consequences of diseases disrupting normal cardiovascular function can be severe or fatal. Recent advancements in cardiovascular medicine have contributed significantly to improving life span and quality for patients by restoring normal cardiovascular function through the use of implantable devices. Examples of these cardiovascular implantable devices include endovascular stents, embolic protection devices and filters, closure devices, heart valve prostheses, cardiac rhythm management devices, such as pacemakers and defibrillators, and left ventricular assist devices. The main objective of this chapter is to provide an overview of device test methods commonly used in the development process from concept to commercialization of implantable cardiovascular devices. It is recognized that general device testing methodology and understanding for developing these cardiovascular devices can be extended to other devices as well as new product concepts under development. Developments of new medical devices are closely regulated by regulatory agencies. U.S. and international regulatory requirements for medical devices and drugs provide specific guidance for bench-top in vitro testing, in vivo animal study, clinical research, manufacturing, sterilization, and post-market surveillance for various device categories. Implantable cardiovascular devices generally fall within the Class II and Class III categories. Commercialization of these products in the United States requires FDA's Premarket Notifications (510Ks), Premarket Approvals (PMAs), or Exemptions. The design control element in the new product development procedure requires detailed documentation of design inputs and outputs as well as rational design verification through testing to ensure device functions and safety. Notably, implantable cardiovascular devices are subjected to very high safety expectation. The inability to perform periodic inspection and repair after device implantation also means that the statistical reliability and safety for these devices must be well established and verified prior to clinical uses. To facilitate discussions, a brief overview of the cardiovascular anatomy and physiology is provided in the beginning of this chapter. Following this overview are sections reviewing exemplary implantable devices used for treating various cardiovascular disorders. The majority of this chapter is then devoted to descriptions of necessary engineering characterizations and design verification test methods most relevant to developing cardiovascular devices for commercialization. Particular emphasis is placed on the attributes that are significantly affected by the biomaterials used in the designs. These include physical properties, such as the transformation temperatures for nitinol self-expanding devices, mechanical properties, structure integrity and durability, corrosion risk assessment as well as functional testing. In addition, biocompatibility testing refers to a battery of testing used to evaluate the biological reaction of the human body to the implanted device. There is a well-recognized ISO standard that governs the specific test protocol requirements (ISO 10993). Safety evaluation studies (in vitro and in vivo) are conducted on a variety of biomaterials, medical devices, and related products to identify the presence of toxins or any other potentially harmful effects. Common assessments of device imaging are also briefly described. These include radiopacity as well as magnetic resonance imaging (MRI) safety and compatibility.

Book excerpt: This User’s Guide is intended to support the design, implementation, analysis, interpretation, and quality evaluation of registries created to increase understanding of patient outcomes. For the purposes of this guide, a patient registry is an organized system that uses observational study methods to collect uniform data (clinical and other) to evaluate specified outcomes for a population defined by a particular disease, condition, or exposure, and that serves one or more predetermined scientific, clinical, or policy purposes. A registry database is a file (or files) derived from the registry. Although registries can serve many purposes, this guide focuses on registries created for one or more of the following purposes: to describe the natural history of disease, to determine clinical effectiveness or cost-effectiveness of health care products and services, to measure or monitor safety and harm, and/or to measure quality of care. Registries are classified according to how their populations are defined. For example, product registries include patients who have been exposed to biopharmaceutical products or medical devices. Health services registries consist of patients who have had a common procedure, clinical encounter, or hospitalization. Disease or condition registries are defined by patients having the same diagnosis, such as cystic fibrosis or heart failure. The User’s Guide was created by researchers affiliated with AHRQ’s Effective Health Care Program, particularly those who participated in AHRQ’s DEcIDE (Developing Evidence to Inform Decisions About Effectiveness) program. Chapters were subject to multiple internal and external independent reviews.

Download or read book Organ Tissue Engineering written by Daniel Eberli and published by Springer. This book was released on 2021-04-22 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The notion of being able to engineer complete organs has inspired an entire generation of researchers. While recent years have brought significant progress in regenerative medicine and tissue engineering, the immense challenges encountered when trying to engineer an entire organ have to be acknowledged. Despite a good understanding of cell phenotypes, cellular niches and cell-to-biomaterial interactions, the formation of tissues composed of multiple cells remains highly challenging. Only a step-by-step approach will allow the future production of a living tissue construct ready for implantation and to augment organ function. In this book, expert authors present the current state of this approach. It offers a concise overview and serves as a great starting point for anyone interested in the application of tissue engineering or regenerative medicine for organ engineering. Each chapter contains a short overview including physiological and pathological changes as well as the current clinical need. The potential cell sources and suitable biomaterials for each organ type are discussed and possibilities to produce organ-like structures are illustrated. The ultimate goal is for the generated small tissues to unfold their full potential in vivo and to serve as a native tissue equivalent. By integrating and evolving, these implants will form functional tissue in-vivo. This book discusses the desired outcome by focusing on well-defined functional readouts. Each chapter addresses the status of clinical translations and closes with the discussion of current bottlenecks and an outlook for the coming years. A successful regenerative medicine approach could solve organ shortage by providing biological substitutes for clinical use - clearly, this merits a collaborative effort.
