## Resource

Today, I want to tell you a story that sounds like it was completely made up for a movie script, but it’s 100% real. Imagine an automotive mechanic in Argentina. He has zero medical training, no background in obstetrics, and no clinical degree. One night, he sees a simple party trick on YouTube: how to get a lost cork out of the inside of an empty wine bottle using nothing more than an inflated plastic bag. Most people would laugh, finish their glass of wine, and move on. But this mechanic, Jorge Odón, looked at that plastic bag and had a radical thought: Could this same basic physics principle be used to safely deliver a trapped baby during second-stage labor? Fast forward through years of engineering refinements, global partnerships, and early clinical pilots, and we get the Odón device- or OdonAssist™. It is, without a doubt, one of the most creative and innovative mechanical concepts to hit the field of operative vaginal delivery in generations. Instead of rigid metal blades applying direct compression, or high-pressure suction cups on the scalp, it uses an inflatable pneumatic cuff wrapped inside a lubricated, double-layered polyethylene sleeve. The inner layer grips the fetal vertex, while the outer layer glides smoothly against the vaginal walls, replacing high friction with plastic-on-plastic sliding action. But, and this is a big "but", as clinicians, we don't practice medicine based on good ideas or clever engineering alone. We practice based on rigorous, reproducible evidence on efficacy and safety. And that’s where the narrative gets complicated. Although the device recently secured CE mark approval in Europe, it is not FDA approved in the United States. Why? Because despite nearly two decades of development, it is still facing a major shortage of…
