1. A device for locating and dilating a natural ostium of a maxillary sinus, the device comprising;

  • (a) an elongate shaft assembly, comprising;

    (i) a substantially rigid straight proximal portion,(ii) a curved distal portion extending from a distal end of the straight proximal portion,(iii) an atraumatic distal tip at the end of the curved distal portion, wherein the curved distal portion has a size and shape to allow passage of the distal portion into a nasal cavity to position the atraumatic distal tip within or near a maxillary sinus ostium, and(iv) an inflation lumen passing through at least part of the shaft assembly; and

    (b) at least one expandable dilator coupled with the shaft assembly, wherein the expandable dilator extends from the distal end of the straight proximal portion to a distal end of the curved distal portion and encompasses the curved distal portion therebetween, wherein the expandable dilator is in fluid communication with the inflation lumen;

    wherein the atraumatic distal tip comprises a ball-shaped tip for enhancing tactile feedback.
