Patent ID: 8277504

Claim:
A method for irrigating a maxillary sinus cavity comprising: advancing a flexible tube having a proximal end and a distal end, a first linear tube segment extending from the proximal end, a first curved tube segment extending from an end of the first linear tube segment, and a second linear tube segment extending from an end of the first curved tube segment toward the first linear tube segment; placing at least a portion of the first linear segment of the flexible tube in a nasal airway; and placing at least a portion of the second linear segment of the flexible tube in the maxillary sinus cavity, wherein after the step of placing the at least a portion of the second linear segment, the second linear segment is positioned such that the second linear tube segment extends from an end of the first curved section in a direction toward the first linear tube segment, and wherein a sinus wall is held between the first and second linear segments of the flexible tube and wherein the flexible tube comprises a passageway extending through the flexible tube, and wherein the second linear segment comprises one or more holes extending from the passageway to an exterior surface of the flexible tube.
