Minneapolis, Minnesota-based Preventice this week received FDA clearance for its BodyGuardian heart rhythm monitor. The monitor is affixed to the skin and monitors heart rate, ECG, respiratory rate and physical activity to detect cardiac arrhythmias, uploading the data via mobile phone to a clinician or physician. The BodyGuardian was developed by Preventice in collaboration with the Mayo Clinic; Mayo developed the algorithms and clinical practices, licensing them to Preventice and also investing in the company. Debut is expected to be late 2012. No patent lawsuits likely here, unless another company chooses to sue Mayo. FDA OKs remote monitoring sensor powered by Mayo Clinic technology (MedCityNews).
