Bringing the bling to improve implants
In a world first, Australian researchers have harnessed the power of diamonds in a breakthrough that could radically improve the way human bodies accept biomedical implants. Researchers from RMIT University have for the first time successfully coated 3D printed titanium implants with diamond. The development is the first step toward 3D printed diamond implants for biomedical uses and orthopaedics - surgical procedures involving the huma...
Brain perceives prosthetic devices as real hands
The human brain can take advantage of brain resources originally devoted to the hand to represent a prosthetic limb, a new UCL-led study concludes. Among people with only one hand, the brain area that enables us to recognise hands can also recognise a prosthetic hand, particularly among those who use a prosthesis regularly, according to the Brain paper. The study provides the first account of how artificial limbs are represent...
Human tissue samples replicate interactions of multiple organs
MIT engineers have developed new technology that could be used to evaluate new drugs and detect possible side effects before the drugs are tested in humans. Using a microfluidic platform that connects engineered tissues from up to 10 organs, the researchers can accurately replicate human organ interactions for weeks at a time, allowing them to measure the effects of drugs on different parts of the body.
Improving mammogram quality
G-ray Medical Sàrl has developed an ultra-high performance detector dedicated to medical applications and in particular mammography. These ultra-high performance detectors will be made in partnership with CSEM, based on G-ray’s latenium technology. Centred on particle-counting X-ray imaging, this unique solution is set to improve the quality of the images obtained from examinations such as breast cancer screening helping earlier dete...
Device could permanently replace failing human hearts
OHSU physicians and researchers are developing what they hope will be the first permanent total artificial heart, which could provide the approximately 75,000 Americans who die of heart failure every year another chance at life.
‘Digistain’ technology offers revolution in cancer diagnoses
The way cancer is diagnosed could soon be more accurate and reliable thanks to a team of British scientists. The team, led by Professor Chris Phillips from Imperial College London, developed a new imaging technology to grade tumour biopsies. Publishing their results in the journal Convergent Science Physical Oncology, they describe how their new method promises to significantly reduce the subjectivity and variability in grading the...
Implanted patches produce organised vascular networks
When cardiovascular disease causes blocked blood vessels, tissues die because the oxygen carried by blood cells cannot reach the tissue. Tissue starved of oxygen is called ischemic. Surgery can remove blockages in large vessels in the heart or legs but is not possible in small vessels; they are just too small to manipulate.
The world’s smallest mechanical heart valve for paediatric patients
Abbott has announced the FDA approved the Masters HP 15mm rotatable mechanical heart valve, the world’s smallest mechanical heart valve, that will allow doctors to treat babies and toddlers in need of a mitral or aortic valve replacement. Until today, surgeons could only use a range of larger-sized valves to replace a paediatric heart valve that could not be repaired, and larger valves are often not suitable given the smaller size of childr...
Bone growth stimulators receive FDA and CE Mark approvals
Orthofix International N.V., has announced the FDA and European CE Mark approvals for its next-generation PhysioStim bone growth stimulators. The PhysioStim devices provide a non-surgical treatment option for patients who have a nonunion fracture to an extremity that has shown no visible signs of healing. These Class III medical devices use a pulsed electromagnetic field (PEMF) signal to induce a low-level electrical field at the fracture si...
Measuring brain signals with soft electronics
Klas Tybrandt, principal investigator at the Laboratory of Organic Electronics, has developed a new technology for long-term stable neural recording. It is based on a novel elastic material composite, which is biocompatible and retains high electrical conductivity even when stretched to double its original length. The result has been achieved in collaboration with colleagues in Zürich and New York.
