Researchers at the Massachusetts Institute of Technology (MIT) have invented a new type of amputation surgery that can help amputees to better control their residual muscles and sense where their “phantom limb” is in space. This restored sense of proprioception should translate to better control of prosthetic limbs, as well as a reduction of limb pain, the researchers say. In most…
Providing the blind with visual impressions: That is the aim of the I See project, in which neuroscientists from the University of Bremen are involved. The approach: A miniature camera collects visual information and translates it into signal patterns that are transferred to brain implants.
Engineers at EPFL’s Center for Artificial Muscles have developed a silicone aorta that can reduce how hard patients’ hearts have to pump. Their breakthrough could offer a promising alternative to heart transplants. “Over 23 million people around the world suffer from heart failure. The disease is usually treated with a transplant, but because donated hearts are hard to come by, there is an…
Someone has a stroke every 40 seconds in the US, resulting in death every 4 minutes. Stroke is the leading cause of disability from a medical condition. When it happens, blood clots or bleeds kill a part of the brain – it goes dark – and can no longer control part of the body. People stop being able to walk, see, talk, or control their hand or arm the way they once did. Although treatments…
Non-degradable prostheses for cardiovascular tissues can be used to replace heart valves and blood vessels, but they can’t stay in the body permanently. In two recent papers, researchers at the Eindhoven University of Technology (TU/e) in collaboration with a number of clinical partners, the Dutch Heart Foundation, and TU/e spin-off companies Suprapolix, Xeltis, and STENTiT have shown how…
Patterns of brain activity can be used to forecast seizure risk in epilepsy patients several days in advance, according to a new analysis of data obtained from clinically approved brain implants by neuroscientists at UC San Francisco, the University of Bern and the University of Geneva.
Increasingly, hospitals use 3D printing in surgery because the technology can enable fast, unique production of patient-tailored tools at relatively low costs. ‘As the technology itself is developing and accelerating at a fast pace, hospitals may be left behind if they choose not to adopt these advances,’ said Limor Haviv, surgical 3D printing designer at 3D4OP. Today, 3D printing is used in…
Researchers at the U.S. National Institute of Standards and Technology (NIST) have developed a new method of 3D-printing gels and other soft materials. Published in a new paper, it has the potential to create complex structures with nanometer-scale precision. Because many gels are compatible with living cells, the new method could jump-start the production of soft tiny medical devices such as…
A bioactive polymer-ceramic composite for fixing implants and restoring bone defects in the skull was developed by an international group of materials scientists from the Russian National University of Science and Technology (NUST) MISIS Center for Composite Materials. An innovative composition of the material based on eggshell-derived bioceramic provides increased strength and biointegration of…
Using highly complex analytical techniques, a group of researchers from Charité – Universitätsmedizin Berlin were able to observe in detail how different metals are released from joint implants and accumulate in the surrounding bone tissue. Findings showed a steady release of metals from various implant components. In contrast to previous assumptions, this was not related to the degree of…
Medtech company BellaSeno announced the initiation of a first-in-human trial of its novel, absorbable soft tissue reconstruction scaffold (Senella). A patient with Pectus Excavatum congenital defect has undergone surgery at Princess Alexandra Hospital in Brisbane, Australia, earlier this month. The procedure was performed by Dr. Michael Wagels, Principal Investigator of the trial and Plastic and…
New coatings on implants could help make them more compatible. Researchers at the Martin Luther University Halle-Wittenberg (MLU) have developed a new method of applying anti-inflammatory substances to implants in order to inhibit undesirable inflammatory reactions in the body. Their study was recently published in the "International Journal of Molecular Sciences".
A new polymeric heart valve with a life span potentially longer than current artificial valves that would also prevent the need for the millions of patients with diseased heart valves to require life-long blood thinning tablets has been developed by scientists at the universities of Bristol and Cambridge. The team's latest in-vitro results, published in Biomaterials Science, suggest that the…
Our body is able to treat many injuries and wounds all by itself. Self-healing powers repair skin abrasions and enable bones to grow back together. However, doctors often have to lend a helping hand to repair bones after a fracture or due to a defect. Increasingly, bone replacement materials are being used, which partially or completely restore the form and function of the bone at the site of the…
Austria-based cochlear and hearing implants technology company Med-El has become one of the first manufacturers worldwide, and the first and only hearing implant manufacturer in the world, to be granted European Medical Device Regulation (MDR) certification. The company made an initial announcement on the newly earned certification after making an early commitment to adopt the MDR in 2016. For…
Researchers at the Hong Kong University of Science and Technology (HKUST), the University of California, Berkeley and Lawrence Berkeley National Laboratory are developing an artificial eye with capabilities close to its human model. The research team published their work on the biomimetic eye in the journal Nature. “Watching sci-fi series such as Star Trek and I, Robot, I thought about making a…
More than 200,000 patients undergo hip replacement surgery in Germany each year. To avoid complications and extend the lifespan of the artificial joint, the implants must be fitted precisely in the acetabulum (hip socket). The procedure, particularly milling the acetabulum, is not only difficult but also the technique is difficult to teach and train. This is where HIPS…
BellaSeno GmbH, a company developing absorbable scaffolds using additive manufacturing technologies, announced a collaboration with Charité – Universitätsmedizin Berlin under the recently established SyMBoD consortium. Under the agreement, BellaSeno will design and manufacture personalized, 3D-printed, absorbable implants suitable for the treatment of diabetes patients with bone defects. The…
Scientists suggest a new strategy that uses induced pluripotent stem cells (iPSCs) to regulate immune reaction to transplanted tissues. The team, led by Professor Ken-ichiro Seino of Hokkaido University’s Institute for Genetic Medicine, found that thymic epithelium cells derived from mouse induced pluripotent stem cells (iPSCs) can regulate immune response to skin grafts, extending their…
