First Claim
Patent Images
1. A method for treating a sinus disease, the method comprising the steps of:
- (a) inserting a portion of a device into a nasal cavity of a patient through a nostril, the device comprising;
a handle comprising a proximal end and a distal end;
an inflation device at least partially disposed within the handle;
a flexible tubular member extending from the distal end of the handle, the flexible tubular member comprising a proximal end, a distal end, an inflation lumen coupled to the inflation device and extending from the proximal end of the flexible tubular member, and a second lumen extending from the proximal end of the flexible tubular member to a medication port; and
an expandable member attached to the flexible tubular member, the expandable member comprising a proximal end and a distal end, wherein the inflation lumen opens, via an inflation port, into the expandable member, wherein the medication port is disposed proximally of the proximal end of the expandable member;
(b) expanding, using the inflation lumen, the expandable member adjacent to the patient'"'"'s choana;
(c) introducing an amount of medication into the nasal cavity, such that at least a portion of the medication enters an ostium of a paranasal sinus of the patient and enters the paranasal sinus and at least a portion of the medication remains in the paranasal sinus for a period of 5 minutes to 40 minutes;
(d) collapsing the expandable member; and
(e) removing the device from the nasal cavity.

Abstract
Methods and devices to quickly and accurately apply medication to a paranasal sinus are disclosed. Additionally, the methods and devices prevent the medication applied to a paranasal sinus from flowing down a patient'"'"'s throat by expanding, using an inflation lumen of a device, an expandable member of the device adjacent to the patient'"'"'s choana.
