Artificial Organs

This book deals with organ failure and the way it can be managed artificially without requiring a transplant. Written by a mixture of European and US physicians and surgeons, each of the chapters compares the artificial organ to what is currently available from the transplant point of view to highlight the current and modern available techniques for organ replacement. The book will be a useful reading for postgraduate students and people interested in modern surgical and medical technology.

The replacement or augmentation of failing human organs with artificial devices and systems has been an important element in health care for several decades. Such devices as kidney dialysis to augment failing kidneys, artificial heart valves to replace failing human valves, cardiac pacemakers to reestablish normal cardiac rhythm, and heart assist devices to augment a weakened human heart have assisted millions of patients in the previous 50 years and offers lifesaving technology for tens of thousands of patients each year. Significant advances in these biomedical technologies have continually occurred during this period, saving numerous lives with cutting edge technologies. Each of these artificial organ systems will be described in detail in separate sections of this lecture.

The worldwide demand for organ transplants far exceeds available donor organs. Consequently some patients die whilst waiting for a transplant. Synthetic alternatives are therefore imperative to improve the quality of, and in some cases, save people’s lives. Advances in biomaterials have generated a range of materials and devices for use either outside the body or through implantation to replace or assist functions which may have been lost through disease or injury. Biomaterials for artificial organs reviews the latest developments in biomaterials and investigates how they can be used to improve the quality and efficiency of artificial organs. Part one discusses commodity biomaterials including membranes for oxygenators and plasmafilters, titanium and cobalt chromium alloys for hips and knees, polymeric joint-bearing surfaces for total joint replacements, biomaterials for pacemakers, defibrillators and neurostimulators and mechanical and bioprosthetic heart valves. Part two goes on to investigate advanced and next generation biomaterials including small intestinal submucosa and other decullarized matrix biomaterials for tissue repair, new ceramics and composites for joint replacement surgery, biomaterials for improving the blood and tissue compatibility of total artificial hearts (TAH) and ventricular assist devices (VAD), nanostructured biomaterials for artificial tissues and organs and matrices for tissue engineering and regenerative medicine. With its distinguished editors and international team of contributors Biomaterials for artificial organs is an invaluable resource to researchers, scientists and academics concerned with the advancement of artificial organs. Reviews the latest developments in biomaterials and investigates how they can be used to improve the quality and efficiency of artificial organs Discusses commodity biomaterials including membranes for oxygenators and cobalt chromium alloys for hips and knees and polymeric joint-bearing surfaces for total joint replacements Further biomaterials utilised in pacemakers, defibrillators, neurostimulators and mechanical and bioprosthetic heart valve are also explored

A comprehensive overview of the latest achievements, trends, and the current state of the art of this important and rapidly expanding field. Clearly and logically structured, the first part of the book explores the fundamentals of tissue engineering, providing a separate chapter on each of the basic topics, including biomaterials stem cells, biosensors and bioreactors. The second part then follows a more applied approach, discussing various applications of tissue engineering, such as the replacement or repairing of skins, cartilages, livers and blood vessels, to trachea, lungs and cardiac tissues, to musculoskeletal tissue engineering used for bones and ligaments as well as pancreas, kidney and neural tissue engineering for the brain. The book concludes with a look at future technological advances. An invaluable reading for entrants to the field in biomedical engineering as well as expert researchers and developers in industry.

Maintaining quality of life in an ageing population is one of the great challenges of the 21st Century. This book summarises how this challenge is being met by multi-disciplinary developments of specialty biomaterials, devices, artificial organs and in-vitro growth of human cells as tissue engineered constructs. Biomaterials, Artificial Organs and Tissue Engineering is intended for use as a textbook in a one semester course for upper level BS, MS and Meng students. The 25 chapters are organized in five parts: Part one provides an introduction to living and man-made materials for the non-specialist; Part two is an overview of clinical applications of various biomaterials and devices; Part three summarises the bioengineering principles, materials and designs used in artificial organs; Part four presents the concepts, cell techniques, scaffold materials and applications of tissue engineering; Part five provides an overview of the complex socio-economic factors involved in technology based healthcare, including regulatory controls, technology transfer processes and ethical issues. Comprehensive introduction to living and man-made materials Looks at clinical applications of various biomaterials and devices Bioengineering principles, materials and designs used in artificial organs are summarised

This book focusses on the development of biomedical membranes and their applications for (bio)artificial organs. It covers the state of art and main challenges for applying synthetic membranes in these organs. It also highlights the importance of accomplishing an integration of engineering with biology and medicine to understand and manage the scientific, industrial, clinical and ethical aspects of these organs. The compendium consists of 11 chapters, written by world renowned experts in the fields of membrane technology, biomaterials science and technology, cell biology, medicine and engineering. Every chapter describes the clinical needs and the materials, membranes, and concepts required for the successful development of the (bio)artificial organs. This text is suitable for undergraduate and graduate students in biomedical engineering, materials science and membrane science and technology, as well as, for professionals and researchers working in these fields.

​Design of Artificial Human Joints & Organs is intended to present the basics of the normal systems and how, due to aging, diseases or trauma, body parts may need to be replaced with manmade materials. The movement of the body generates forces in various work situations and also internally at various joints, muscles and ligaments. It is essential to figure out the forces, moments, pressure etc to design replacements that manage these stresses without breaking down. The mechanical characterization of the hard and the soft tissues are presented systematically using the principles of solid mechanics. The viscoelastic properties of the tissue will also discussed. This text covers the design science and methodology from concept to blueprint to the final component being replaced. Each chapter will be a brief overview of various joint/organ replacement systems. Engineers working on artificial joints and organs, as well as students of Mechanical Engineering and Biomedical Engineering are the main intended audience, however, the pedagogy is simple enough for those who are learning the subject for the first time.

The number of factors implicated in the regulation of cell proliferation and differentiation is already considerable and more are continually being identified. This book concentrates on tumor necrosis factor (cachectin) and lymphotoxin, but includes observations of their interactions with other cytokines, especially the interferons and interleukins. TNF can be either cytostatic or cytotoxic to cultured cell lines, and a variety of mechanisms are proposed, ranging from DNA fragmentation to activation of phospholiopases. TNF is also reported to stimulate the growth of normal fibroblasts "in vivo." The "in vivo" actions of TNF described here include haemorrhagic necrosis of tumors, cachexia, effects on the vasculature, and antiparasitic and antiviral activities. Also presented is some interesting data from the first stages of clinical trials of TNF as an anticancer agent.
