Abstract:
1. A system for treating a paranasal sinus by dilating a natural or manmade paranasal sinus opening, said system comprising: (a) an elongate shaft having a proximal end, a distal end and an outer diameter sized to allow the elongate shaft to be inserted into a patient's nose; (b) an expandable dilation device coupled with distal end of the elongate shaft, the expandable dilation device being expandable from a first configuration to a second configuration; the elongate shaft being advanceable, with the dilation device in its first configuration, through the patient's nose to a position where the dilation device is positioned within the paranasal sinus opening; the dilation device being expandable, while positioned within the paranasal sinus opening, from the first configuration to the second configuration, said second configuration being sized to cause dilation of the paranasal sinus opening, wherein said dilation device in said second configuration expands with sufficient force to cause breakage or rearrangement of bone which surrounds the paranasal sinus opening; and the expandable dilator being thereafter removable from the paranasal sinus opening such that the paranasal sinus opening remains dilated after removal of the dilator therefrom.
