Available in PDF, EPUB and Kindle. Book excerpt: For several years now scientific and medical sLaff have recognised the risks of toxicity of certain metals contained in alloys used in Lhe manufacture of biomaterials protheses, implants, and artificial organs. A number or scientific and industrial research centres have focussed their investigations in this direction and international societies and commissions have organised meetings with specialists from complementary disciplines in attendance in attempts to guage the importance of biological risks and to determine the toxicity of certain metals, with the aim of establishing preventive measures and guidelines. In the last century great efforts have been made to reduce unwanted biological effects caused by orthopaedic implants. The problems of pain and infection were overcome and the development of modern technology has resulted in a convincing decrease in corrosion problems and mechanical failure, such that ostosynthesis and endoprosthesis have rapidly progressed beyond the level of tentative investingation.llowever, a number of problems still remain to be solved, such as the influence of the material type on the healing process and its relative speed. The increasing use of cobalt-,chromium-and nickel-containing alloys in surgical and dental implants has raised various questions concerning the biological consequences of chronic internal release of these elements in the human body. A total of 55 delegates representing 16 countries heard presentations of fundamental aspects, local and remote tissue response, immunopathology, clinical aspects, and manufacturing qual ity control issues.

Download or read book Biomaterials for Artificial Organs written by Michael Lysaght and published by Elsevier. This book was released on 2010-12-20 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Download or read book Friction and Wear of Cobalt molybdenum and Cobalt molybdenum chromium Alloys for Prosthetics written by Robert L. Johnson and published by . This book was released on 1971 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies were conducted in heptane with cobalt alloys on a disk-and-conforming-shoe apparatus simulating the single motion of a human hip joint. The results showed that cobalt-molybdenumchromium alloys were brittle; that the surface finished by grinding fragmented locally; and that, subsequently, abrasion of sliding surfaces occurred. When the ground surfaces were altered by glass-bead blasting, fragmentation during the wear process was minimized. Particles loosened by the grinding.process were removed, and the bead-blasted surface provided pockets to entrap debris. Friction and wear for the bead-blasted cobalt-molybdenum-chromium alloy were significantly lower than for vitallium.
