Abstract
A nasal dilator that prevents the outer wall tissue of the nasal passages of the nose from drawing in during breathing comprises a truss member. The truss member includes a flexible strip of material having a first end region, a second end region and an intermediate segment. The first and second end regions are adapted to engage the outer wall tissue of first and second nasal passages of the nose. The intermediate segment is configured to traverse a portion of a nose located between the first and second nasal passages. The truss member further includes first and second resilient bands secured to the strip of material adjacent opposite edges of the intermediate segment. The resiliency of the first and second resilient bands acts to stabilize the outer wall tissue and thereby prevents the outer wall tissue of the first and second nasal passages from drawing in during breathing.
