Visual signs of disease can often be spotted within affected tissues, and advances in histopathology have provided clinicians with powerful diagnostic tools to spot those signs. Microscopes are the cornerstone of this trade, and although they have proven to be extremely useful, they do suffer from some limitations. They are effectively 2D imaging devices that don't offer a good perspective on the volumetric nature of things at small scales, and they only detect light, which can't sense clinically important properties such as tissue stiffness. The optical fiber imaging sensor has...Read More

Researchers at McGill University in Canada have developed a method to create and deliver brain implants that are a similar in consistency to the brain itself, which is a soft gelatinous tissue. The delicate silicone implants are created using sugar molds and delivered using a sugar needle, and their delicate consistency helps to ensure that they cause minimal irritation within the brain and reduce the chances of a foreign body response. Brain implants have a variety of uses, from identifying the regions of the brain responsible for epilepsy to producing...Read More
Shaip is an online platform that focuses on healthcare AI data solutions and offers licensed healthcare data designed to help construct AI models. It provides text-based patient medical records and claims data, audio such as physician recordings or patient/doctor conversations, and images and video in the form of X-rays, CT scans, and MRI results. Like most algorithms, healthcare AI requires diverse data to train machine learning algorithms to identify clinical anomalies, diseases, or cancers more accurately. Vatsal Ghiya, co-founder and CEO of Shaip, is an expert in improving healthcare AI by using...Read More
Traumatic brain injuries (TBI) often lead to cognitive disabilities and permanent neural tissue damage, for which effective therapies do not exist. The serious cognitive impairments that patients experience and the burden on caretakers can be enormous, necessitating a constant search for treatments that may help. Researchers at University of Georgia have now reported in journal Science Advances about a remarkable hydrogel they developed that seems to protect the brain from tissue loss after a TBI and even repair neural networks that were damaged. The material, which the researchers call "brain...Read More
Neurolutions, a company with offices in Santa Cruz, CA and St. Louis, MO, won FDA de novo authorization to introduce its IpsiHand stroke rehab system in the United States. This is the first approval of a brain-computer interface technology for the rehabilitation of stroke patients, and it promises a faster and more complete recovery of hand function in many patients. The IpsiHand system takes advantage of the uninjured side of the brain to trigger the opening and closing of a robotic exoskeleton placed over the affected arm. The patient wears...Read More
Medtronic has won FDA approval for its Pipeline Flex Embolization Device with Shield Technology. The original Pipeline Flex was the first commercially available flow diverter for brain aneurysms. Shield Technology, a novel surface treatment that now encompasses the device, helps to reduce the tendency of the device itself to produce clots. A few days ago New York University's Langone Health center in New York City was the first hospital in the U.S. to employ the Pipeline Flex Embolization Device with Shield Technology. "The Pipeline Flex-Shield that we used today at...Read More

Researchers at Brigham and Women’s Hospital and MIT have developed 3D printed shields to protect the gastrointestinal tract from the side effects of radiotherapy. Using CT scans, the devices can be custom printed to suit each patient’s anatomy. The materials they're made of contain high atomic number elements that help to shield tissues from gamma and X-rays. Radiotherapy can be highly effective at targeting tumors and helping to shrink them. However, it can also have significant consequences for nearby healthy tissues. The side effects can be particularly pronounced in the...Read More

Researchers at Aalto University in Finland have developed an ultrasonically actuated needle that can retrieve a large amount of tissue during a biopsy, without the pain and complications associated with using bigger needles. The technique could be very useful when clinicians need to obtain tissue samples for molecular tumor diagnostics, since obtaining high quality samples is crucial, given the expense of molecular profiling procedures. The technique may also help to reduce patient inconvenience associated with repeat biopsies because of an initial poor tissue sample. "Biopsy yields – the amount of...Read More
Fecal incontinence can be extremely challenging for those who suffer it. The condition can be embarrassing, making it difficult for people to tell others or even their doctor about it, and it is more common than you might think. Fecal incontinence can affect anyone, but a key group of patients includes women during menopause, in whom it is often associated with previous pelvic trauma, such as that which occurs during child-birth. Treatment options are relatively limited and either tend to be minimalist, such as lifestyle changes, or pretty intense, such...Read More

Researchers at Ohio State University have developed new software that allows them to rapidly design and simulate DNA nanorobots. Previously, it was challenging to engineer such tiny devices, but now researchers can map out their design in minutes. DNA-based devices have significant promise as medical technologies with potential applications in drug delivery and diagnostics. Researchers are still pursuing the sci-fi dream of tiny machines that can enter our bodies and help to heal us. This latest development brings that reality a little closer. Developing DNA-based robots and devices at such...Read More
Melanoma, which accounts for over 70 percent of all skin cancers, occurs when pigment producing cells called melanocytes multiply uncontrollably. This cancer is typically diagnosed through visual inspection of Suspicious Pigmented Lesions (SPLs), and such early detection of lesions in a physician's office are often life-saving. However, there are several disadvantages with this approach, including the high volume of potential lesions one has to biopsy and test before confirming a diagnosis. To overcome these issues, researchers from MIT and a few other institutions around Boston, have developed a new deep...Read More
