Premarket evidence — what FDA accepted

Device typesamd
source quote (p.6)
Cydar EV is a Software-as-a-Service product and consists only of the software running on Cydar's cloud servers. Cydar EV, the subject device, is a software medical device, it does not contact the patient, nor does it control any life sustaining device.
