Abstract: An apparatus and method for anesthetizing various portions of a patient's nasal sinuses. For example, a kit can be provided that includes a first agent configured to modulate a rate of absorption of a subsequently-applied topical agent by one or more nasal structures. The kit also includes a first applicator configured to apply the first agent to a first portion of the one or more nasal structures. The kit also includes a second agent configured to anesthetize the first portion of the one or more nasal structures subsequent to application of the first agent and a second applicator configured to apply the second agent to the second portion of the one or more nasal structures.

Abstract: An apparatus that includes a container portion and a coupler portion. The container and coupler are, in one embodiment, mated via an adapter that includes a one-way valve. The coupler includes a second one-way valve. In use, a fluid source, such as a vial, is connected to the coupler. An air source, such as a syringe is also connected to the coupler. Air from the syringe is introduced to the vial via the second one-way valve. The second one-way valve prevents fluid from the vial from being drawn into the syringe. Introduction of air from the syringe into the vial forces fluid from the vial into the container via the first one-way valve. The first one-way valve prevents the fluid from escaping the container.
