Abstract
A method of treating diseased ethmoid sinuses in a patient with a therapeutic agent includes providing an injection device comprising an elongate member having a proximal end, a distal tip or end, and a lumen extending between the distal tip and the proximal end, the proximal end being operatively coupled to a source of the therapeutic agent. The distal tip of the injection device is inserted at least partially within an interior portion of an ethmoid air cell. The therapeutic agent is then injected into the interior portion of the ethmoid air cell using the injection device, the therapeutic agent being delivered via the lumen in the elongate member.

A method of treating diseased ethmoid sinuses in a patient with a therapeutic agent comprising:
- providing an injection device comprising an elongate member having a proximal end, a distal end having a cutting head having a plurality of cutting surfaces arranged about a distal surface of the cutting head and facing in a distal direction, and a lumen extending between the distal end and the proximal end, the proximal end being operatively coupled to a source of the therapeutic agent;
- advancing the injection device so as to place the distal end adjacent to a wall of an ethmoid air cell;
- forming a passageway in the ethmoid air cell by rotating the cutting head against the wall of the ethmoid air cell so as to engage the plurality of cutting surfaces against the wall of the ethmoid air cell;
- injecting the therapeutic agent into an interior portion of the ethmoid air cell with the elongate member of the injection device, the therapeutic agent consisting essentially of a fluid or fluid-like substance;
- and
- withdrawing the injection device from the ethmoid air cell.
