I agree that advertising is a sum of its parts. It is like the company is conveying the functions of the part that is made for. In other words, any device that is made is approved by FDA on the basis of it’s functions, working and it’s liability. Advertising is conveying those details to everyone. This details are necessary in order to get an FDA approval ultimately making it a part of that device. Also many companies disclose only good details which is inappropriate. There should be a full disclosure in order to avoid any type of misconceptions to the consumer or the patients.
