Abstract
A force-directional nasal surgery dilatation device for use in a medical procedure such as sinuplasty, correction of deviated septum, and expansion of sinus cavities and nasal passages. An inflatable balloon is affixed to the distal end of a shaft for supporting and guiding the balloon into position for a nasal surgery procedure involving a patient. The shaft includes an inflation passageway associated for introducing an inflation medium into the balloon. The device further includes a force distribution member affixed to the inflatable balloon that provides a relatively rigid surface for applying distributed force against a tissue in the patient's nasal cavity upon inflation of the balloon. The force distribution member can include a pair of generally planar articulated adjacent surfaces attached along a hinge line between the surfaces.
