Device and method for treatment of sinusitis
A method of treating a constricted sinus passageway in a frontal sinus of a patient includes forming an artificial passageway into the frontal sinus of the patient with a tool. An elongate member having an inflation member thereon is inserted through the passageway. The inflation member is positioned with the constricted sinus passageway and the inflation member is expanded so as to expand at least a portion of the constricted sinus passageway.
1. A method of treating a constricted passageway in a frontal sinus of a patient comprising:
forming an artificial access passageway in a floor of the frontal sinus with a tool, the artificial access passageway providing an access point to the frontal sinus from directly outside the skull of the patient;
inserting an elongate member through the passageway, the elongate member having an inflation member disposed thereon;
positioning the inflation member within the constricted sinus passageway; and
expanding the inflation member so as to expand at least a portion of the constricted sinus passageway.
2. The method of claim 1 , wherein the inflation member is positioned within the constricted passageway under visualization.
3. The method of claim 2 , wherein the visualization comprises placement of a visualization tool into the nasal cavity.
4. The method of claim 3 , wherein the visualization tool comprises an endoscope.
5. The method of claim 1 , wherein the inflation member comprises an expandable balloon.
6. The method of claim 5 , wherein the elongate member comprises a balloon catheter.
7. The method of claim 1 , wherein the inflation member is positioned within the constricted sinus passageway by advancing the elongate member over a wire guide passing through the passageway.
8. The method of claim 7 , wherein the wire guide is positioned within the constricted passageway under visualization.
9. The method of claim 8 , wherein the visualization comprises placement of a visualization tool into the nasal cavity.
10. The method of claim 9 , wherein the visualization tool comprises an endoscope.
11. The method of claim 1 , wherein the inflation member is positioned using one or more markers contained thereon.
12. The method of claim 1 , wherein the constricted sinus passageway comprises the frontal sinus ostium.
13. The method of claim 1 , wherein the tool comprises a drill tool.
