Abstract: An external nasal dilator comprising resilient and engagement elements is provided. A greater portion of the plan view surface area of the nasal dilator supports moisture vapor transmission (MVT) compared to prior art nasal dilators having a nearly identical plan view surface area and the same or similar functional resiliency. The engagement element surface area relative to the surface area of the resilient element of nasal dilators of the present invention is significantly greater compared to prior art nasal dilators having a nearly identical plan view surface area and the same or similar functional resiliency. In use the nasal dilator stabilizes and/or expands nasal passage outer wall tissues, and prevents said tissues from drawing inward during breathing.

Abstract: A nasal dilator comprises adjacent, substantially parallel resilient members having mid-sections substantially parallel to the dilator longitudinal centerline and end portions that diverge obliquely away from the centerline. The dilator may comprise a laminate of vertically stacked material layers that each have a different peripheral shape, and greater or lesser surface area, from that of the others. The dilator may comprise resilient members that diverge or curve symmetrically about the dilator longitudinal centerline such that a shape of a resilient member on one side of a lateral centerline is a mirror image of its shape on the opposite side of the lateral centerline.
