AssistENT is a medical technology company in Baltimore, Maryland, developing impactful solutions to disorders of the ears, nose, and throat. We design intuitive consumer devices that transform users​ quality of life and less invasive medical instruments that will empower physicians to deliver optimal patient outcomes at reduced costs. Our first product, the N-Stent Breathing Aid, is the first nasal dilator designed for use throughout the day. Much like a contact lens, users insert and remove the device daily, experience an instant improvement in nasal breathing upon insertion, and comfortably wear the device in public without detection. N-Stent’s key value lies in its ability to instantly enhance nasal breathing without the risk and inconvenience of reconstructive surgery or the stigma and discomfort of prevailing sleep aid nasal dilators.
