I disagree, in fact, some schools I visit had fields in BME that I personally think has nothing engineering in it. Engineering is design and build so if they just build something (internal, external) without designing, it is not engineering either. My interest is designing and building devices but there are people who targets cellular level. I did some research in Biomedical sciences department and all i did was to find mechanism of how something affects something in the body (drug affects inflammation. Protein affects cell’s function, etc)
