Forbes -- There may not be three people in the world less likely to invent and launch a groundbreaking medical device than Jeff Chimenti, Billy Procida and A.J. Santella. Chimenti’s day job is playing keyboard alongside former Grateful Dead stars Bob Weir and Phil Lesh for post-Garcia offshoot bands including The Dead and Ratdog. Procida is a real estate developer who befriended Chimenti ten years ago and has since advised both bands on business matters including the recent release of Grateful Deadopoly. Santella is a roadie.
