Nasal congestion, obstruction relief, and drug delivery

摘要

A nasal insert may include a wall in the shape of a tube, the wall including a first end defining a first orifice and a second end defining a second orifice. The first end may have a diameter, diagonal measurement, or cross-sectional area larger than that of the second end. The first end may define at least one break in the wall, so that the first end incompletely encircles the first orifice. The second end may completely encircle the second orifice. 18 1alt 130 130 170 FIG. 17 140 FIG. 18 170
