Medical devices

MIT researchers have developed a new implant that in the future could be used to deliver insulin to patients for up to a month, potentially enabling patients to control diabetes without injections, reports Tony Ho Tran for the Daily Beast. In the future, the researchers hope to “develop a device for humans that would be roughly the size of a stick of gum,” writes Tran. “The implant could also be used to deliver things like drugs or proteins to help treat other diseases in humans as well.”

Researchers at MIT and elsewhere have developed a medical device that uses AI to evade scar tissue build up, reports Andrew Paul for Popular Science. “The technology’s secret weapon is its conductive, porous membrane capable of detecting when it is becoming blocked by scar tissue,” writes Paul. 

Callie Gade and Nate Bonham of CNN’s Discovery Daily Podcast spotlight how researchers from MIT developed a 3D printed replica of the human heart that can help doctors customize treatments for patients before conducting open heart surgery or other intrusive procedures. “These more patient-specific heart replicas can help future researchers develop and identify treatments for people with unique health problems,” says Gade.

Dr. Akshay Syal, a medical fellow for NBC News, discusses how MIT researchers have developed a new technique to 3D print custom replicas of the human heart.

Bloomberg reporter Tanaz Meghjani writes that MIT researchers created a new system to 3D print a customized replica of the human heart, which could help improve replacement valve procedures. The new system “mimics blood flow and pressure in individual diseased hearts, suggesting a way to predict the effects of various replacements and select the best fit, avoiding potential leakage and failure,” Meghjani writes.

MIT engineers have developed a new technique for 3D printing a soft, flexible, custom-designed replica of a patient’s heart, report Gabrielle Emanuel and Amy Sokolow for WBUR. The goal of the research is to “provide realistic models so that doctors, researchers and medical device manufacturers can use them in testing therapies for different types of heart disease,” Emanuel and Sokolow explain.

MIT scientists have developed a miniature antenna that could one day be used to help safely transmit data from within living cells “by resonating with acoustic rather than electromagnetic waves,” reports Andrew Chapman for Scientific American. “A functioning antenna could help scientists power, and communicate with, tiny roving sensors within the cell,” writes Chapman, “helping them better understand these building blocks and perhaps leading to new medical treatments.”

Popular Science reporter Helen Bradshaw writes that MIT researchers have improved the energy capacity of nonrechargeable batteries, the batteries used in pacemakers and other implantable medical devices, by employing a new type of electrolyte. “Expanding the life of primary batteries may also make them sustainable contenders,” writes Bradshaw. “Fewer batteries will have to be used in pacemakers as their lifespans increase, decreasing overall battery waste in addition to reducing the number of battery replacement surgeries needed.”

A stamp-sized reusable ultrasound sticker developed by researchers in Prof. Xuanhe Zhao’s research group has been named one of the best inventions of 2022 by TIME. “Unlike stretchy existing ultrasound wearables, which sometimes produce distorted images, the new device’s stiff transducer array can record high-resolution video of deep internal organs (e.g. heart, lungs) over a two-day period,” writes Alison Van Houten.

Principal research scientist Leo Anthony Celi speaks with Associated Press reporter Maddie Burakoff about how pulse oximeters can provide inaccurate readings in patients of color. Celi highlights how oxygen levels can also be measured by drawing blood out of an artery in the wrist, the “gold standard” for accuracy, but a method that is a a bit trickier and more painful. 

Forbes contributor Marija Butkovic spotlights Gloria Ro Kolb ’94, the founder of medical device company Elidah, which is developing “an external, home-use treatment for female urinary incontinence.” 

Washington Post reporter Pranshu Verma writes about how Prof. Dina Katabi and her colleagues developed a new AI tool that could be used to help detect early signs of Parkinson’s by analyzing a patient’s breathing patterns. For diseases like Parkinson’s “one of the biggest challenges is that we need to get to [it] very early on, before the damage has mostly happened in the brain,” said Katabi. “So being able to detect Parkinson’s early is essential.”

Forbes contributor Jennifer Kite-Powell spotlights how MIT researchers created a new AI system that analyzes radio waves bouncing off a person while they sleep to monitor breathing patterns and help identify Parkinson’s disease. “The device can also measure how bad the disease has become and could be used to track Parkinson's progression over time,” writes Kite-Powell.

A new tool for diagnosing Parkinson’s disease developed by MIT researchers uses an AI system to monitor a person’s breathing patterns during sleep, reports Hiawatha Bray for The Boston Globe. “The system is capable of detecting the chest movements of a sleeping person, even if they’re under a blanket or lying on their side,” writes Bray. “It uses software to filter out all other extraneous information, until only the breathing data remains. Using it for just one night provides enough data for a diagnosis.”

Boston Globe reporter Hiawatha Bray speaks with Radio Boston host Tiziana Dearing about how MIT researchers developed an artificial intelligence model that uses a person’s breathing patterns to detect Parkinson’s Disease. The researchers “hope to continue doing this for other diseases like Alzheimer’s and potentially other neurological diseases,” says Bray.
