NiTi Surgical Solutions introduces bowel anastomosis device NiTi Surgical Solutions' shape memory surgical rings, clips, and appliers represent the next generation in internal tissue anastomosis devices. The devices are designed for treatment of colorectal, small bowel, gastric, and upper gastrointestinal disease requiring surgical anastomosis. The device may provide physicians with a staple-free anastomosis technology for bowel and certain colon surgeries, potentially eliminating bleeding at the anastomosis site and minimizing complications following surgery. learn more > Stryker reduces cycle time by 20% with Siemens CNC machining system Stryker Corporation of Kalamazoo, Michigan, a medical device and equipment manufacturer, has frequent manufacturing requirements for low quantities of highly specialized devices. Stryker recently acquired the DMG Model DMC 635 V eco, a powerful three-axis vertical milling center with an 8000 rpm spindle and a 20-position tool changer, run by the Siemens Sinumerik 810D CNC and ShopMill software. Tolerances down to the ten-thousandths are being achieved, surface finishes are improved, and overall machining cycle times are reduced by 20%. learn more > Proposed medical device tax would harm U.S. competitiveness A new analysis by a leading tax expert raises serious tax and health policy issues. The new tax could shift technological innovation abroad as the average tax rate for the device and diagnostics industry would rise from 23 percent to nearly 50 percent. learn more > Biomaterials in Orthopaedic Surgery By Federico Ángel Rodríguez-González This new book from ASM reviews the biomaterials (metallic, non-metallic, and bone allografts) used for orthopaedic applications and explains the engineering and clinical aspects of their use within the human body. Case studies are used to explain and illustrate the concepts. Specific applications include internal and external bone fracture fixation, hip and knee joint replacements, spine implants and disc prostheses, and the application of structural bone allografts for patients with bone tumors (sarcoma). learn more > Testing effects of RFID systems on medical devices Radio frequency identification systems are widely used for applications that include inventory management, package tracking, toll collection, passport identification, and airport luggage security. These systems are used in medical environments to track patients, equipment assets, and staff members. The Georgia Tech Research Institute recently began developing testing protocols for evaluating potential issues with electromagnetic interference in the health care setting. learn more > Metallic glass for bone surgery It is possible that broken bones will soon be fixed using metallic glass. Implants made of magnesium-base alloys are particularly promising. These light metals are mechanically stable and ductile, and degrade quickly and completely by releasing ions which are tolerated by the body. ETH Zurich materials researchers have produced an innovative magnesium-zinc-calcium alloy in the form of a metallic glass which is biocompatible and shows fundamentally different degradation behaviour from other magnesium-base alloys. learn more > Boston Scientific’s biliary stents receive FDA 510(k) clearance Boston Scientific Corporation has received 510(k) clearance from the U.S. Food and Drug Administration to market its WallFlex(®) Biliary RX fully and partially covered stents for the palliative treatment of malignant bile duct strictures.. The stent has greater flexibility to aid with placement in tortuous anatomies and new features such as flared ends that may reduce the risk of migration. learn more > Edwards Lifesciences to expand its manufacturing and R&D capability Edwards Lifesciences Corporation will be developing a new state-of-the-art manufacturing facility in Draper, Utah which will enable it to accommodate future growth and to significantly expand its manufacturing and R&D capability. The company will transfer manufacturing of its cannula and embolic protection devices utilized by cardiac surgeons during open-heart surgery from its existing Midvale, Utah facility to the new facility in the first half of 2010. learn more > Polymer platform for artificial hips and knees DSM Biomedical has developed an easily cross-linkable ultra-high molecular weight polyethylene (UHMWPE). The new polymer platform creates a family of UHMWPE polymers that incorporate small, highly reactive molecules that can produce the required cross-linking network at significantly lower radiation doses, thereby lessening the adverse effects on the polymer’s mechanical properties and allowing for stronger implants with better long-term stability. learn more >  e-Elastic: the most comprehensive source for news about Nitinol Keep up with the latest advances and applications for Nitinol and other superelastic materials. The newsletter publishes quarterly in January, April, July, and October. View the inaugural issue. Register to receive the newsletter. Join ASM Shape Memory and Superelastic Technologies Society. learn more > World's smoothest vapor-deposited diamond by Advanced Diamond Technologies Advanced Diamond Technologies has introduced UNCD Horizon, an ultra-smooth vapor-deposited diamond coating. UNCD Horizon improves the smoothness by an order of magnitude to 1 nm, and brings the surface roughness of diamond films to levels comparable to electronic grade silicon wafers, opening up new vistas for the application of diamond into a wide variety of electronic and biomedical devices. learn more > Brain implants coated with polymer nanotubes show 30% improvement The new brain implants developed at University of Michigan are coated with nanotubes made of poly(3,4-ethylenedioxythiophene) (PEDOT), a biocompatible and electrically conductive polymer that has been shown to record neural signals better than conventional metal electrodes. The research could eventually lead to more effective treatment of neurological disorders such as Parkinson's disease and paralysis. learn more > back to top > |
