There's another possible interpretation of a design/manufacturing customer spec that components must be "medically approved".
Many makers of component materials and devices are gunshy about the use of their products in applications that have an adverse history regarding civil lawsuits in the event of less-than-optimal performance. Such component makers frequently impose terms of sale that attempt to establish an agreement-by-purchase not to use their products in those product types--frequently, in medical devices--and to indemnify the component maker against judgments, damage to reputation, costs of staff time, legal counsel costs, etc.
Such conditions and contractural barriers are very common in regard to two use-types...life safety systems, and implantables.
Thus, "medically approved" might refer to a component maker not establishing such constraints against medical-device use.
