Inflatable nasal packing device with two non-elastic, flexible bags oversized relative to nasal cavities
First Claim
1. An inflatable apparatus for insertion into a nasal passage of a patient for controlling epistaxis, comprising:
- an insertion tube having a first inlet for receiving gas or fluid from a first source and a first outlet for the gas or fluid received from the first source and a second inlet for receiving gas or fluid from a second source and a second outlet for the gas or fluid received from the second source;
a first bag including sealed sidewalls comprising non-elastic material sealably connected to the insertion tube with a fully-inflated interior volume defined by the bag sidewalls and in fluid communication with the first outlet, wherein the exterior of the first bag has a flat surface and the interior volume of the first bag defined by the sidewalls is greater than the volume of the anterior nasal cavity of the patient; and
a second bag including sealed sidewalls comprising non-elastic material sealably connected to the insertion tube with a fully-inflated interior volume defined by the bag sidewalls and in fluid communication with the second outlet, wherein said second bag partially overlaps with said first bag and the exterior of the second bag has a flat surface and the interior volume of the second bag defined by the sidewalls is greater than the volume of the posterior nasal cavity and nasopharynx of the patient.

Abstract
An inflatable nasal packing device, and method of use, for insertion in a patient'"'"'s nasal cavity to control bleeding or epistaxis. The device includes a flexible insertion tube, a first inflatable bag attached to and surrounding an anterior section of the tube, and a second inflatable bag attached to and surrounding a posterior section of the tube. The tube has three lumens for providing separate fill passageways to the two bags to allow independent filling and pressurization and for providing an air passageway through the device even when the bags are inflated. Both bags have walls of non-elastic, flexible material with fixed surface areas defining interior volumes when inflated that are larger than the anterior nasal cavity and the posterior nasal cavity and nasopharynx.

13. An inflatable nasal packing device, comprising:
-
an insertion tube comprising three lumen including an air passageway lumen extending the length of the tube with an opening at each end of the tube, a first fill lumen with an inlet at one end of the tube and an outlet in a first portion of the tube, and a second fill lumen with an inlet adjacent the inlet for the first fill lumen and an outlet in a second portion of the tube; a first bag formed of non-elastic, flexible material positioned about the first portion of the tube and sealed to the tube with a pair of circumferential end seals that are spaced apart on the tube such that the first bag encloses a first portion of the tube; and a second bag formed of non-elastic, flexible material positioned about the second portion of the tube and sealed to the tube with a pair of circumferential end seals that are spaced apart on the tube such that the second bag encloses a second portion of the tube wherein said first and second bag have flat outer surfaces that partially overlap one another. - View Dependent Claims (14, 15, 16)
