FORCE-DIRECTIONAL NASAL SURGERY DILATATION DEVICE

摘要

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.

1. A force-directional nasal surgery dilatation device for use in a nasal surgery, comprising:
an inflatable balloon; a shaft for supporting the balloon at a distal end and guiding the balloon into position for a procedure involving a patient; an inflation passageway associated with the shaft for introducing an inflation medium into the balloon; and a force directional member adjacent a side of the balloon; wherein, when the balloon is inflated in a nasal passage or sinus ostia of the patient, the amount of force applied to tissue adjacent the force directional member is less than the amount of force applied to other tissue in the nasal passage or sinus ostia of the patient.
