Nasal dilator apparatus
A “frame-like” nasal dilator that is configured to open a user's nasal passages and maintain the user's nasal passages in an open position to improve breathing. The nasal dilator has an overall shape that mimics the shape of a butterfly, with right and left stent sections or “wings” that apply gentle pressure to open the nasal passages.
1 . A nasal dilator apparatus, comprising:
first and second intranasal stents;
first and second support sections; and
a bridge section;
wherein each support section comprises an arcuate anterior portion, a substantially straight upper segment extending from the arcuate anterior portion and merging into a corresponding stent, and a substantially straight lower segment extending from the arcuate anterior portion and merging into a corresponding side of the bridge section;
wherein the bridge section symmetrically bridges the first and second support sections in a spaced apart lateral position, wherein the stents are spaced apart, each stent comprising a semicircular curved portion that extends posteriorly in relation to the anterior portion of the corresponding support section, that curves upwardly from the corresponding substantially straight upper segment, and that then extends anteriorly and curves toward the substantially straight upper segment to terminate at a distal end that is spaced apart from the substantially straight upper segment, such that the stent can extend in a posterosuperior direction and approximately follow the curve of the inferior edge of the piriform aperture of a nose; and
wherein the bridge section is positioned distal to the anterior portions of the support sections.
2 . The apparatus of claim 1 :
wherein the stents are spaced apart and develop from the first and second support sections along two adjustably inclined planes forming a flare;
the stents having each an adjustable curvature and being each arranged to apply gentle pressure to open the nasal passage without applying pressure to the lesser alar cartilage.
3 . The apparatus of claim 2 , wherein the adjustable curvature comprises a radius of curvature adjustable from about 4 mm to about 7.5 mm.
4 . The apparatus of claim 1 , wherein the apparatus comprises a flexible metal alloy material.
5 . The apparatus of claim 4 , wherein the metal alloy material comprises stainless steel, nickel-titanium or titanium-molybdenum.
6 . The apparatus of claim 1 , wherein at least a portion of the apparatus is covered with a biocompatible material.
7 . The apparatus of claim 6 , wherein the biocompatible material comprises a polymer.
8 . The apparatus of claim 1 , wherein the apparatus comprises a single resilient wire formed into the stents, support sections, and bridge section.
9 . The apparatus of claim 1 , wherein the apparatus comprises a biocompatible material formed into the stents, support sections, and bridge section.
10 . The apparatus of claim 9 , wherein the biocompatible material comprises a polymer.
11 . The apparatus of claim 1 , wherein each stent and associated support section in combination has a wing-like shape.
12 . The apparatus of claim 1 , wherein the stents have a posteriorly divergent lateral spacing.
13 . The apparatus of claim 1 :
wherein said stents, said support sections, and said bridge section are in combination a unitary structure.
14 . The apparatus of claim 13 :
wherein the apparatus comprises a flexible metal alloy material formed into the stents, support sections, and bridge section; and
wherein the metal alloy material is selected from the group consisting of stainless steel, nickel-titanium and titanium-molybdenum.
15 . The apparatus of claim 14 , wherein at least a portion of the apparatus is covered with a biocompatible polymer material.
16 . The apparatus of claim 13 , wherein the apparatus comprises a biocompatible polymer material formed into the stents, support sections, and bridge section.
