METHODS FOR TREATING SINUS DISEASES

摘要

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.

主权项

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; andan 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.
