Abstract
Abstract An intranasal device to be used in combination with septum operations consists of a breathing channel and an inflatable balloon positioned in side by side relation to one another on one side of a thin plate which is shaped to conform to the interior anatomy of the nasal cavity. The balloon is connected to a pressure balancing device for controlling the pressure in the balloon, and valve means are provided for setting a maximum allowable pressure in the balloon.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
127 words
An intranasal device for insertion into a nasal cavity following a septum operation, comprising a thin plate which is shaped to conform to the interior anatomy of the nasal cavity, a breathing channel attached to one side of said plate, an inflatable balloon of thin-walled material attached to said one side of said plate in laterally spaced side-by-side relation to said breathing channel, the side of said plate opposite to said one side being adapted to abut the nasal septum to provide support for the septum when said plate and the breathing channel and balloon attached thereto are inserted into the nasal cavity, and inflation means attached to said balloon for inflating said balloon, said inflation means including means for maintaining a controlled pressure in said balloon.
Claim 2
Dependent Claim
127 words
An intranasal device for insertion into a nasal cavity following a septum operation, comprising a thin plate which is shaped to conform to the interior anatomy of the nasal cavity, a breathing channel attached to one side of said plate, an inflatable balloon of thin-walled material attached to said one side of said plate in laterally spaced side-by-side relation to said breathing channel, the side of said plate opposite to said one side being adapted to abut the nasal septum to provide support for the septum when said plate and the breathing channel and balloon attached thereto are inserted into the nasal cavity, and inflation means attached to said balloon for inflating said balloon, said inflation means including means for maintaining a controlled pressure in said balloon.
Claim 3
Dependent Claim
