Zero evidence Covid impacted the IDE process whatsoever. All blame there is on RDGL mismanagement. Covid did put RDGL out of business for several months in 2021 (per 2022 new year update), but that only impacted IsoPet business, as Radiogel isn't even a business yet. And who cares about money losing IsoPet at moment, when RDGL can't survive without Radiogel IDE approval?
