Abstract:
1. A method for delivering a substance to a location within a paranasal sinus or nasal cavity, or an opening into a paranasal sinus or nasal cavity of a human or animal subject to treat a disorder, said method comprising the steps of: obtaining or providing a device that comprises: inserting the introducer device into the nose to a position where its distal end opening is aligned with the paranasal sinus or nasal cavity or the opening into the paranasal sinus or the opening into the nasal cavity; causing the pusher to advance, thereby delivering the self-expanding structure out of the distal end opening of the introducer device so that the self-expanding structure self-expands within the paranasal sinus or nasal cavity or the opening into the paranasal sinus or the opening into the nasal cavity; and leaving the self-expanding structure in place for a period of time over which the biodegradable material degrades and wherein the therapeutic substance is released.
