Nearly 7.5 million American adults take insulin, but getting the dosage right can be tough, says Ed Damiano, co-founder of Beta Bionics. Inspired by his diabetic son, Damiano spent 20 years creating the iLet, a credit-card-size, AI-powered smart device that links to a tube plugged into a patient’s body. Similar to existing options, it monitors glucose levels every five minutes. Unlike others on the market, it dispenses appropriate insulin microdoses when needed, fully automatically. The device was approved by the FDA in May, and recently gained Medicare and Medicaid approval.
