A significant medical event is expected in 1992: the first human use of a fully implantable, long-term cardiac assist device. This timely volume reviews the artificial heart program-and in particular, the National Institutes of Health's major investment-raising important questions. The volume includes: Consideration of the artificial heart versus heart transplantation and other approaches to treating end-stage heart disease, keeping in mind the different outcomes and costs of these treatments. A look at human issues, including the number of people who may require the artificial heart, patient quality of life, and other ethical and societal questions. Examination of how this technology's use can be targeted most appropriately. Attention to achieving access to this technology for all those who can benefit from it. The committee also offers three mechanisms to aid in allocating research and development funds.
Fighting heart disease with machines and devices-- Multiple approaches to building artificial hearts : technological optimism and political support in the early years -- Dispute and disappointment : heart transplantation and total artificial heart implant cases in the 1960s -- Technology and risk : nuclear-powered artificial hearts and medical device regulation -- Media spotlight : the Utah total artificial heart -- Clinical and commercial rewards : ventricular assist devices -- Securing a place : therapeutic clout and second-generation VADs -- Artificial hearts in the 21st century

​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.
It wasn’t supposed to be this hard. If America could send a man to the moon, shouldn’t the best surgeons in the world be able to build an artificial heart? In Ticker, Texas Monthly executive editor and two time National Magazine Award winner Mimi Swartz shows just how complex and difficult it can be to replicate one of nature’s greatest creations. Part investigative journalism, part medical mystery, Ticker is a dazzling story of modern innovation, recounting fifty years of false starts, abysmal failures and miraculous triumphs, as experienced by one the world’s foremost heart surgeons, O.H. “Bud” Frazier, who has given his life to saving the un-savable. His journey takes him from a small town in west Texas to one of the country’s most prestigious medical institutions, The Texas Heart Institute, from the halls of Congress to the animal laboratories where calves are fitted with new heart designs. The roadblocks to success —medical setbacks, technological shortcomings, government regulations – are immense. Still, Bud and his associates persist, finding inspiration in the unlikeliest of places. A field beside the Nile irrigated by an Archimedes screw. A hardware store in Brisbane, Australia. A seedy bar on the wrong side of Houston. Until post WWII, heart surgery did not exist. Ticker provides a riveting history of the pioneers who gave their all to the courageous process of cutting into the only organ humans cannot live without. Heart surgeons Michael DeBakey and Denton Cooley, whose feud dominated the dramatic beginnings of heart surgery. Christian Barnaard, who changed the world overnight by performing the first heart transplant. Inventor Robert Jarvik, whose artificial heart made patient Barney Clark a worldwide symbol of both the brilliant promise of technology and the devastating evils of experimentation run amuck. Rich in supporting players, Ticker introduces us to Bud’s brilliant colleagues in his quixotic quest to develop an artificial heart: Billy Cohn, the heart surgeon and inventor who devotes his spare time to the pursuit of magic and music; Daniel Timms, the Brisbane biomedical engineer whose design of a lightweight, pulseless heart with but a single moving part offers a new way forward. And, as government money dries up, the unlikeliest of backers, Houston’s furniture king, Mattress Mack. In a sweeping narrative of one man’s obsession, Swartz raises some of the hardest questions of the human condition. What are the tradeoffs of medical progress? What is the cost, in suffering and resources, of offering patients a few more months, or years of life? Must science do harm to do good? Ticker takes us on an unforgettable journey into the power and mystery of the human heart.
This book is a detailed practical guide to the use of ventricular assist devices and total artificial hearts to provide mechanical circulatory support (MCS) in patients with end-stage heart failure. It explains why MCS may be indicated, which patients require MCS, when and how to implant ventricular assist devices or a total artificial heart, and how to avoid potential complications of MCS. Management throughout the period of care is described, from preimplantation to follow-up, and both typical and atypical cases are discussed. The text features numerous helpful tips and tricks relating to surgical and nonsurgical management and is supported by a wealth of high-quality illustrations that document the preoperative evaluation and implantation techniques. Heart transplantation remains the gold standard for the treatment of patients suffering from end-stage heart failure, but the shortage of donors has led to an increase in the use of MCS. This book will assist all physicians, and especially cardiologists and anesthesiologists, who are involved in the care of these patients.
