It's crazy how each substantially similar innovation arrives about 9ish years after the last one. Must be the natural cycle of drug research?

Not that there would be any generic manufacturers chomping at the bit to make the doohickies anyway. Think of the insulin or epinephrine pens. Drugs are cheap. Doohicky is expensive. Probably all sorts of regulations, certifications etc related to manufacturing them not to mention distribution channels, insurance coverageand who knows what barriers.
