I'll explain it like I would to a child: Just because two toys have batteries doesn’t mean they do the same thing. RadioGel and YntraDose both use Y-90, sure — but RadioGel injects tiny Y-90 particles that spread through a tumor and solidify in place, like pouring Jell-O into every corner. YntraDose glues big Y-90 beads into one spot — totally different game. And no, the core RadioGel tech isn’t expired or duplicable — its current patents cover how those particles are made, how they’re suspended, and how the gel behaves in the body. That’s why it’s FDA-tagged as a Breakthrough Device — a regulated device, not just a “gel with Y-90.” So no, YntraDose can’t just copy or leapfrog it.
