How syncing wearables with AI chatbots can accelerate recovery time

Smart integration of AI chatbots and data collected by wearable devices can help patients and health care providers respond to early signs of illness.

More effective public health and medical interventions could save 1.2 million lives per year, according to the Organization for Economic Cooperation and Development (OECD).

But the healthcare industry isn’t solely responsible. There is usually a gap between identifying an illness and seeking medical attention. Even when a patient feels unwell, they often don’t know the best path of care and may avoid medical support because they minimize their symptoms, lack physical access to local healthcare, worry about healthcare costs, or simply don’t have a doctor.

Wearable medical devices can bridge this gap by monitoring vital signs — often remotely — to determine irregular behavi…

Understanding medtech AI with alpacas, llamas and Hologic VP of R&D/Innovation Mike Quick

When Hologic VP of R&D/Innovation Mike Quick talks about artificial intelligence and medtech AI, he draws on his personal experience as an amateur alpaca farmer.

He and his wife had a herd of nearly a dozen alpaca when they lived in the Boston area. Then they moved to Arizona, where they now have three alpaca on a small farm in Phoenix.

“They’re a lot of fun,” he said in an interview with Medical Design & Outsourcing. “… The difference between llamas and alpacas — because it’s a common misconception of what they are — is a great way to talk about AI and the difference between machine learning and deep learning and how to learn to tell two different things apart.”

Dr. Marisa Cruz envisions a future where unobtrusive wearable devices with advanced sensors will continuously measure and record actionable biodata without patients having to lift a finger.

Cruz is an endocrinologist and internist who serves as chief medical officer at Empatica, which develops wearable devices for monitoring patient physiology with the ultimate goal of improving clinical outcomes.

In 2011, Empatica spun out of an MIT lab focused on wearable sensors for continuous, passive patient monitoring. That technology is made possible by ever-shrinking sensors and batteries, gains in effective computing, and materials and manufacturing methods that result in comfortable and intuitive…

FDA and VA Ventures Innovation Institute partner on new medical device testing tools

The Department of Veterans Affairs’ VA Ventures Innovation Institute in Seattle will host up to a dozen FDA staffers in a new collaboration to develop and share new tools for medical device testing safety and efficacy.

The agencies intend to provide developers of devices and new technology with off-the-shelf tools that can help streamline regulatory review and get products to patients faster. FDA staff from the Center for Devices and Radiological Health (CDRH) will focus on regulatory science. Their partners at the VA’s Veterans Health Administration (VHA) will provide clinical context for test development and provide hands-on training and other immersive experiences for innovators wishing to utilize the tools.

Researchers at MIT and the University of Rochester Medical Center have developed a device to monitor a Parkinson’s patient at home.

Collecting data at home could help provide a less subjective measurement than evaluations at the doctor’s office, which can be affected by outside factors. The technology could also help pharmaceutical and biotech companies developing new therapies for Parkinson’s, which is the world’s fastest-growing neurological disease.

In a one-year study with 50 patients, machine learning algorithms analyzed the data to help clinicians track Parkinson’s progression and medication response more effectively than periodic evaluations in a medical facility, MIT said in a news release. The study fund that gait speed declined ne…

Mayo Clinic develops AI childbirth risk prediction tool for women in labor

Mayo Clinic researchers are using AI algorithms to calculate childbirth risk while women are in labor in an effort to reduce the rate of cesarean delivery and complications.

The machine learning algorithms — a type of device known as Software as a Medical Device (SaMD), where the software is the device rather than a mechanical device — analyze patterns of changes for women in labor.

“This is the first step to using algorithms in providing powerful guidance to physicians and midwives as they make critical decisions during the labor process,” senior author Dr. Abimbola Famuyide said in a news release. “Once validated with further research, we believe the algorithm will work in real time,…

Two leaders from Johnson & Johnson connected with Medical Design & Outsourcing this week to discuss the medical device maker’s partnership with Microsoft, the cloud’s potential for medical devices and to offer advice for medtech engineers designing for connectivity.

In January, New Brunswick, New Jersey–based Johnson & Johnson (NYSE:JNJ) named Redmond, Washington-based Microsoft (NASDAQ:MSFT) as its preferred cloud provider for digital surgery solutions and partner on building out J&J’s digital surgery platform and internet of things (IoT) device connectivity.

Johnson & Johnson Group CIO and Global Vice President of Medical Devices Larry Jones and Office of Digital Innovation Leader Peter Schulam (who also serves as global head of medical affairs, clinical a…

The FDA today released its first plan to regulate artificial intelligence/machine learning (AI/ML)-based Software as a Medical Device (SaMD).

The plan is a response to feedback received from the agency’s April 2019 discussion paper, “Proposed Regulatory Framework for Modifications to Artificial Intelligence/Machine Learning-Based Software as a Medical Device.”
