Abstract
The present invention discloses a nasal dilator comprising at least one breathable layer of adhesive-coated high MVTR layer, such as a polyurethane film, one or more adhesive-coated high modulus “spring” elements for dilating the nasal passages by applying a tension force to the skin, and a carrier delivery system. The carrier delivery system comprises a separation line or split through the carrier to allow for easy delivery of the nasal dilator. The carrier aids in the handling and delivery of the thin adhesive-coated high MVTR layer.
