Claim:
1. An external nasal dilator consisting of: a first end region adapted to engage the outer wall tissues of a first nasal passage and a second end region adapted to engage the outer wall tissues of a second nasal passage; an intermediate segment connecting the first and second end regions and configured to traverse the bridge of the nose located between the first and second nasal passages; a flexible strip of base material defining the first and second end regions and the intermediate segment; a resilient band traversing the entire length of a first side of the flexible strip of base material; an adhesive covering the entire second side of the flexible strip of base material for removably engaging the dilator to the nose of the wearer; wherein the dilator including the flexible strip of base material, resilient band and adhesive are slotted inwardly from both lateral ends, terminating short of the intermediate segment, thereby dividing the dilator into four resilient branches comprising two lower branches and two upper branches, each resilient branch having slot side edges wherein the flexible strip of base material, resilient band and adhesive coterminate at the slot side edges and extended tabs, wherein the two upper branches are parallel to the two lower branches along an entire length of a longitudinal axis between the upper and lower branches; wherein each resilient branch further comprises an inwardly slotted portion that forms a first curved surface and a second curved surface, wherein the first curved surface coterminates with the resilient band and the second curved surface extends beyond the length of the resilient band; wherein the upper branches are between 15% and 30% shorter than the lower branches.
