Any good examples? When I was looking into this a few years ago most of them did not have favourable reviews by doctors and individuals. Do they still require batteries or are they passive?
These are passive devices. Some examples include Thornton Adjustable Positioner (TAP) devices, SomnoDent, Prosomnus, and others.
