A system includes a platform configured for insertion into a users nostril and a catheter. The platform includes a board having first and second major surfaces and a support extending from the board. The support includes an aperture therethrough. The catheter includes an inflatable tube and a lumen having first and second ends, the first end connected to the tube and the second end connected to a pressurized fluid source for inflating the tube. The tube is configured for insertion through the aperture. A method includes inserting a platform into a users nostril, inserting a catheter through an aperture of the platform, and inflating a tube of the catheter. Inflating the tube is accomplished by introducing a pressurized fluid through a lumen of the catheter, to thereby cause the tube to conform to a passage of the users nasal or pharyngeal region.
