The vast majority of FDA-approved medical devices enabled by artificial intelligence or machine learning are concentrated in radiology and cardiovascular care, according to an analysis by Rock Health. Rock Health used data from FDA clearances and approvals from 1997 to 2021 to determine where these devices are used the most. Here are the AI/machine-learning enabled devices by therapeutic area, the Oct. 8 report found:

Emergency response data: RapidSOS, a startup whose software platform automatically transmits data from 911 callers to emergency responders, secured $25 million in new funding, led by the investment firm Energy Impact Partners in its Series B funding round. The company closed the round with $55 million in funding including $30 million collected last year. The funding accelerates RapidSOS's work partnering with thousands of public safety agencies, most major public safety software providers, and connected device companies to transform emergency response and disaster management Remote medical documentation: Tech-enabled remote documentation company Augmedix uses natural-language-processing technology and remote medical documentation experts to help reduce the burden of medical documentation for physicians. The San Francisco-based company landed $19 million in Series B funding that included investments from Redmile Group, McKesson Ventures, DCM Ventures, Wanxiang Healthcare Investments, and others. Augmedix provides clinicians with hardware, smartphones or Google Glass, to stream the clinic visit to a cloud-based platform.

From a venture investment perspective, digital health is having a record year--one that has come as something of a surprise against the backdrop of federal policy uncertainty. But is investor interest extending into artificial intelligence applications for healthcare? That's a topic we'll explore at Xconomy's Healthcare A.I.
