1. An intranasal expandable occlusion device, comprising:
an expandable body having a first end and an opposite, second end, and comprising:
at least one flexible expandable sponge having an anterior end, an opposite, posterior end and an exterior surface defined therebetween;
a flexible inflatable balloon that is completely surrounded by and is completely in contact with the at least one flexible expandable sponge so that no portion of the flexible inflatable balloon is uncovered by the at least one flexible expandable sponge; and
a flexible expandable cover that is impermeable to liquids and overlies a portion of the exterior surface of the at least one expandable sponge and extends over the posterior end and along sides of the at least one expandable sponge so as to define an uncovered portion including the anterior end and a portion proximate the anterior end of the at least one expandable sponge uncovered by the flexible expandable cover that provides an access to the at least one expandable sponge, wherein the access is an opening that allows fluid to reach and be collected by the at least one expandable sponge;
wherein the first end and the second end of the expandable body are respectively coincident with the anterior end and the posterior end of the at least one flexible expandable sponge, and the expandable body has no through passageway extending from the posterior end to the anterior end of the at least one flexible expandable sponge such that when the expandable body rests in an airway of a structure in use, the expandable body operably occludes the airway bilaterally for preventing drainage from passing through the expandable body;
an inflation catheter connected to the flexible inflatable balloon through the uncovered portion of the at least one expandable sponge; and
a suction catheter connected to the at least one expandable sponge through the uncovered portion of the at least one expandable sponge, for suctioning the fluid collected by the at least one expandable sponge.
