US 6,607,546 B1 · Nasal catheter

Abstract

The nasal catheter system will provide an improvement over existing devices that do not fill the recesses of the nose, do cause significant pain and still do not stop nosebleeds very effectively. The objectives are achieved through the design of a version of the device that has two inflatable bags, which in the preferred embodiment are not elastic balloons. The anterior bag is much larger in volume than the anterior nasal cavity. The design of the bag is generally cylindrical but has deep ridges projecting outward producing a “pleated” design with ribs running along and parallel to the axis of the catheter. Alternate designs include a circumferential ring or capillary tube fingers projecting outward. Any surface projection that serves to create additional surface area or any projection that winds and flows into the meatus recesses of the nasal cavity with greater ease will accomplish some aspect of the desired objective.

Dependent claims

A nasal catheter system comprising:

a) a catheter having a first anterior fluid channel, a first anterior output opening, a first anterior input port, and a first external section;
and
b) a first anterior bag fixedly attached to the catheter, the first anterior bag having a first anterior chamber, a first outer surface, a first front end, a first middle portion and a first rear end, and a plurality of first anterior elongated ridges attached to the first outer surface and spanning over about the first middle portion, the plurality of first anterior elongated ridges having a plurality of first anterior ridge cavities, wherein the first anterior ridge cavities are in communication with the first anterior chamber;
whereby the nasal catheter system may be inserted into a first anterior nasal cavity and when the catheter is filled with a fluid, the fluid flows through the first anterior fluid channel and into the first anterior bag, thereby expanding the first anterior bag and producing pressure upon the first anterior nasal cavity.
