New throat device aims to help people with severe swallowing issues eat without choking
NCT ID NCT02296528
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early study tested a device called the Swallow Expansion Device (SED) in 4 people who could not swallow safely and relied on a feeding tube. The device was designed to mechanically open the upper throat muscle to allow food and liquid to pass without entering the airway. The study was terminated early, so results are limited.
