I reported 3 years ago (see here) when Israel’s Vectorious Medical raised funds to trial its V-LAPTM microcomputer that monitors for imminent heart failure. The device has just been successfully implanted in the first human trials in a six-minute procedure, under local anesthesia. It is said to be the world’s first digital, wireless, battery-less device that can communicate from deep within the body.
