Abstract
An apparatus for creating an accessory maxillary ostium for purposes of ventilation, irrigation, or procedural work within the maxillary antrum. An introducer having a ventilation tube and grommet is provided to create and then provide access through the accessory maxillary ostium. An irrigation catheter may be advanced through the ventilation tube in order to irrigate or express the contents of the sinus cavities. A secondary irrigation catheter or a balloon catheter may be advanced through an outer irrigation catheter, deeply into the sinus cavity, in order to irrigate or express the contents of the sinus cavities. Moreover, the balloon catheter may alternatively or additionally be employed to for dilation of the natural ostium. Still further, a device for delivering drugs, fluids or the like, may be coupled to the ventilation tube for delivery of same.

13. A method of ventilating the sinus, comprising the steps of:
-
guiding a ventilation tube and a sharp cutting distal tip toward the wall of a sinus cavity using a first tool; puncturing the wall with the sharp cutting distal tip; pressing the ventilation tube partially through the wall, until a proximal flange is adjacent the sinus wall; retracting the first tool with the ventilation tube in place with the proximal flange adjacent the side of the sinus cavity wall; and guiding a further tool toward the ventilation tube and operating the tool. - View Dependent Claims (14, 15, 16, 17, 18, 19)
