Scientists in Australia are gearing up for clinical trials of a brain implant that may restore limited sight in blind people. Developed at Monash University in Melbourne, the Gennaris system involves bypassing the eye completely and targeting the vision center of the brain. A person would wear a pair of glasses outfitted with a camera that, via a computer, feeds what it is seeing to the brain implant. The wireless implant is positioned on the surface of the brain and it can generate 172 different bright spots that the person...

Materials
Researchers at the National Institute of Standards and Technology (NIST), which is part of the U.S. Department of Commerce, have developed a new technique to 3D print soft objects, such as hydrogels, at a higher resolution than previously possible. The technique uses X-rays or electron beams to crosslink the gels, helping to create complex structures at a nanometer scale. The technique could have potential in creating engineered tissue constructs for regenerative medicine applications. Soft materials, such as hydrogels, have significant potential in tissue engineering, given their mechanical properties and biocompatible...Read More

Gyroscope Therapeutics, a retinal gene therapy company, has developed the Orbit subretinal delivery system (SDS). The technology is designed to deliver therapies to the retina without the need for invasive procedures, such as vitrectomies, which involve removing the gel-like substance within the eye, or retinotomies, which involve making a hole in the retina. The company hopes that by combining medical devices that allow minimally invasive delivery with innovative gene therapies they can develop transformative therapeutic strategies. Gyroscope Therapeutics recently announced that the FDA has granted 510(k) clearance for the Orbit...Read More

Researchers at the Harvard Wyss Institute have developed a rapid, inexpensive, and very sensitive malaria test that harnesses the power of CRISPR. The new technique does not require complicated sample preparation or processing, and it could allow for rapid on-site testing in low resource regions, aiding the campaign to eliminate malaria. Determining where malaria is being contracted is key to eradicating and treating it. However, such regions are usually remote and typically lack medical resources, making testing challenging. Current tests for malaria have poor sensitivity and often require expensive and...Read More

Philips has just unveiled its Azurion Lung Edition system that combines a number of technologies that improve how minimally invasive procedures in the lungs are performed. The system relies on Cone Beam CT imaging, to provide a high resolution 3D view of the lungs, along with X-ray guidance for clear awareness of the anatomy being worked on and the tools within. A combination of additional hardware and software features work together to help with thoracoscopic surgeries, biopsies, and lesion ablations that are common when diagnosing and treating lung cancer. Using...Read More

EchoNous, a developer of novel ultrasounds, has found a way to leverage multiple critical clinical technologies within a single device. The result is KOSMOS, a handheld 3-in-1 device consisting of an ultrasound, electronic stethoscope, and an ECG, all linked via artificial technology. When COVID-19 was hitting NYC earlier this year, EchoNous was able to use KOSMOS to help diagnose COVID patients and to inform on treatment strategies. We had a lovely chat with Dr. Richard Hoppmann, a key member of EchoNous, Clinical Professor of Internal Medicine at the University of...Read More

Researchers at Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland have developed a mini intestine on a chip that closely mimics the morphology and cellular composition of the small intestine. The device could be useful for advancing personalized medicine, drug screening, and even paving the way for researchers to grow new tissues and organs in the lab for use in regenerative medicine. Creating organoids typically involves assembling stem cells to form miniature versions of tissues or organs. However, existing approaches are limited in how closely they can mimic native human...Read More

Electroencephalography (EEG) devices are incredibly helpful in diagnosing and monitoring certain brain disorders, such as epilepsy and strokes. However, they are not particularly user-friendly or convenient, with specialized technicians performing time consuming procedures, such as skin preparation, to get patients ready to undergo the procedure. A combination of messy gels and wires also makes for an uncomfortable and inconvenient experience for patients. In response, Zeto Inc., a medtech startup based in California, has developed a new EEG device that sits on the head like a bicycle helmet. The headset does...Read More

The orthodontics market is expected to realize significant growth in the coming years with projected growth to $9.72 billion by 2026 ($4.06 billion in 2018). Technology advancement in the industry has largely been driven by invisible, clear aligners that can be removed for eating and cleaning. Aligners progressively reposition teeth through controlled force without the tightening required with traditional metal braces. Despite aesthetics and ease of use, an estimated 80% of patients have alignment problems that still require braces for treatment, restricting the market share that leading aligner solutions, like...Read More

Soft exosuits that provide assistive force during movement could be a game changer for patients with mobility issues. Such devices can help enhance rehabilitation and assist patients while they perform everyday tasks. The idea with such technology is that the soft suit feels almost like a piece of clothing and applies force gently and evenly to affect natural movement. This latest suit, the ReStore exosuit from ReWalk Robotics, has been FDA cleared for use in patients who have experienced a stroke and now have a mobility issue. A recent trial...Read More

Researchers at the City University of Hong Kong have developed a face mask containing laser-induced graphene that can kill bacteria and has demonstrated potential in deactivating coronaviruses. The graphene layer has antibacterial properties and can generate heat when exposed to sunlight, which may underlie its ability to deactivate coronaviruses. The researchers hope that such masks could help to reduce viral transmission and infection during the current COVID-19 pandemic. Face masks are an important part of our arsenal in the fight against COVID-19, but if used incorrectly, they can pose an...Read More

Ophthalmology
The pupil of the eye allows light to reach the retina, and a number of vision disorders are related to irregularities in the iris that surrounds the pupil. People with aniridia, for example, have some or all of the iris missing, exhibiting a large pupil that results in unfocused vision. Now, a collaboration between Imec, a Belgian research institution, Ghent University, Spain's Instituto de Investigación Sanitaria Fundación Jiménez Díaz, and Holst Centre in The Netherlands, has led to the development of an artificial iris integrated inside a contact lens that...Read More
