A nasal dilator of vertically laminated layers, each consisting of one or more components. The laminated layers form a unitary truss with end regions for engaging outer wall tissues of a users nasal passages and for traversing the bridge of the nose. The dilator includes means to direct its resilient properties comprising material separations or shape discontinuities formed in at least one region of the truss and extending through at least one layer of the dilator. Said material separations or discontinuities may comprise an opening, relief cut, slit or notch, and may be configured to separate or vertically protrude from the dilator when it is in use. The separations transform the angle of focused delaminating spring biasing forces generated by the resilient layer from primarily peel forces into primarily shear forces, and further redistribute the transformed forces to tissue-engaging surface areas extending outward and beyond the separations.
