Medical devices

Materials World reporter Sarah Morgan spotlights how MIT researchers have “combined the waterproof stickiness of mussel-inspired polymers with the germ-fighting properties of mucus-derived proteins, mucins, to form a cross-linking gel that strongly adheres to surfaces.” The new adhesive could be used to coat medical implants to prevent infection and bacteria build-up. Postdoc George Degen explains: “We demonstrate adhesion to wet tissue and metal-oxide surfaces, important substrates for biomedical applications. Moreover, our mucin-derived hydrogels discourage the formation of bacterial biofilms, raising the possibility of antifouling coatings.” 

Prof. Hugh Herr joins the BBC’s Shiona McCallum to discuss a program by the K. Lisa Yang Center for Bionics aimed at bringing prosthetics to those who suffered forced amputations during the Sierra Leone Civil War. “When we train a young person on how to construct an arm or leg prothesis we’ve impacted the country for solidly forty years,” Herr says. “That person’s going to be living in that country and contributing to their community for a very long time. That’s exciting.” 

MIT engineers have developed a new adhesive, low-cost hydrogel that can stop fibrosis often experienced by people with pacemakers and other medical devices, reports for Maria Bolevich Interesting Engineering. “These findings may offer a promising strategy for long-term anti-fibrotic implant–tissue interfaces,” explains Prof. Xuanhe Zhao. 

ShareAmerica reporter Lauren Monsen spotlights Prof. Dina Katabi for her work in advancing medicine with artificial intelligence. “Katabi develops AI tools to monitor patients’ breathing patterns, hear rate, sleep quality, and movements,” writes Monsen. “This data informs treatment for patients with diseases such as Parkinson’s, Alzheimer’s, Crohn’s, and ALS (amyotrophic lateral sclerosis), as well as Rett syndrome, a rare neurological disorder.”

MIT researchers have developed a new type of spring-like device that uses a flexible element to help power biohybrid robots, reports Brian Heater for TechCrunch. “The muscle fiber/flexure system can be applied to various kinds of robots in different sizes,” Heater writes, adding that the researchers are, “focused on creating extremely small robots that could one day operate inside the body to perform minimally invasive procedures.”

Bloomer Tech, a health tech startup founded by Alicia Chong Rodriguez SM ‘17, SM ’18, is working to “address the gender gap in health care, which has led to less clinical trial representation and fewer resources to diagnose and treat women with various diseases,” reports Steph Solis for Axios. The startup is prepared “to launch a clinical trial for bras that could help detect heart irregularities and other conditions that can lead to heart disease,” writes Solis.

Prof. Xuanhe Zhao speaks with Amerigo Allegretto of AuntMinnie.com about his work developing a new ultrasound sticker that can measure the stiffness of internal organs and could one day be used for early detection and diagnosis of disease. “Due to the huge potential of measuring the rigidity of deep internal organs, we believe we can use this to monitor organ health,” Zhao explains.

Alicia Chong Rodriguez SM ’17, SM ’18 founded Bloomer Tech, a health tech startup that aims to improve health care diagnostics for women using medical-grade data to develop new therapies and care models, reports Carol Eisenberg for The Washington Post. Rodriguez and her colleagues "developed, patented and tested flexible washable circuits to turn articles of clothing into devices that can relay reams of information to the wearer’s smartphone,” writes Eisenberg.

Scientific American reporter Payal Dhar spotlights how MIT engineers developed a beating, biorobotic replica of the human heart that could be used to “simulate the workings of both a healthy organ and a diseased one.” The replica, "which pumps a clear fluid instead of blood, is hooked up to instruments that measure blood flow, blood pressure, and more," writes Dhar. "It’s also customizable: the user can change the heart rate, blood pressure and other parameters, then watch how these changes affect the heart’s function in real time.”

Researchers from MIT have developed, “nanoelectronics they hope can one day enter the brain and treat conditions like Alzheimer’s by monitoring some of these brain patterns,” reports Elizabeth Hlavinka for Salon. “Their device, which they call Cell Rover, serves as a sort of antenna that can help external devices monitor cells.”

President Biden has awarded Prof. Emeritus Subra Suresh ScD '81, the former dean of the MIT School of Engineering, the National Medal of Science for his “pioneering research across engineering, physical sciences, and life sciences,” reports Alexa Gagosz for The Boston Globe. Prof. James Fujimoto '79, SM '81, PhD '84, research affiliate Eric Swanson SM '84, and David Huang '85, SM '89, PhD '93 were awarded the National Medal of Technology and Innovation, “the nation’s highest award for technical achievement.”

STAT reporter Annalisa Merelli writes that the 2023 Lasker Award has been given to Prof. James Fujimoto, research affiliate Eric Swanson SM ’84 and David Huang PhD ’93 for their work advancing the diagnosis of eye disease. Fujimoto, Swanson and Huang developed “optical coherence tomography (OCT) — the first noninvasive technology allowing doctors to see high-resolution images of the retina.”

Prof. James Fujimoto, research affiliate Eric Swanson SM ’84 and David Huang PhD ’93 have won a Lasker Award for their work inventing optical coherence tomography, which can “detect conditions like macular degeneration and diabetic retinopathy earlier than previous methods, preventing blindness,” reports Noah Weiland and Cade Metz for The New York Times. “O.C.T. now is commonly used in ophthalmology offices, where the patient simply rests a chin and forehead against an instrument for a brief scan,” write Weiland and Metz. “The method, invented in 1991, offers a staggering amount of detail about the retina.”

Prof. James Fujimoto, research affiliate Eric Swanson SM ’84 and David Huang PhD ’93 have been honored with the Lasker Award for their work for their work inventing “imaging technology that revolutionized how ophthalmologists diagnose diseases of the eye," reports Jonathan Saltzman for The Boston Globe. The scientists were recognized for developing “optical coherence tomography, or OCT, the first technology that enabled doctors to see a two- and three-dimensional cross-sectional image of the retina,” Saltzman explains. “This painless scan takes less than 10 minutes, and is now the standard of care for diagnosing retina diseases.”

7 News spotlights how MIT researchers have developed a new implantable device that could provide diabetes patients with insulin without using injections. “What we’ve been able to show is that with a minimally invasive implant that is sitting just under the skin, we’ve actually been able to sort of achieve a diabetic reversal,” explains Research Scientist Siddharth Krishnan.
