For reference, OP is talking about the 510(k) process. One of the issues with that process is that an approved medical device may end up with a whole tree of "derivative" devices approved through the 510(k) process. If that original device is then found to have problems and has its approval removed, those derivative devices do not also become unapproved.

That may be true, but the FDA is no longer run by fiduciaries of the United States.

It sounds like they are trying to fly under the FDA thresholds for regulation as a medical device and be considered a low risk "wellness device" which makes no medical diagnostic claims and has low risk. This is why it is in spas and not doctor's offices.

> FDA may consider certain products that use non-invasive sensing (e.g. optical sensing) to estimate, infer, or output physiologic parameters (e.g. blood pressure, oxygen saturation, blood glucose, heart rate variability) to be general wellness products when such outputs are intended solely for wellness uses, and provided they:

• are non-invasive and not-implanted;

• do not involve an intervention or technology that may pose a risk to the safety of users or other persons if specific regulatory controls are not applied;

• are not intended for the diagnosis, cure, mitigation, prevention, or treatment of a disease or condition;

• are not intended to substitute for an FDA-authorized, cleared, or approved device;

• do not include claims, functionality, or outputs that prompt or guide specific clinical action or medical management; and

• do not include values that mimic those used clinically unless validated (e.g. manufacturer testing, peer-reviewed clinical literature) to reflect those values

do they need FDA approval to have a good impact? it doesn't need to be a licensed medical device for me to interpret the data, and then verbally tell my doctor what's wrong

this is similar to how people get a lot of medical value out of chatgpt today
