A non-invasive bladder monitor, software to combat lung cancer and an app that identifies high-risk sexual behavior in adolescents are three technologies being developed right here in the Denver area. The three companies took the top awards at the recent Prime Health Challenge $150,000 competition that started with 30 contestants. Littleton’s dBMEDx won the $75,000 top prize for its BBS Revolution, a device that scans a person’s bladder to determine volume — and nix the invasive catheter.
