Irrigation and aspiration devices and methods
Irrigation and/or aspiration devices and methods may be configured to aspirate and irrigate alone, sequentially, or concurrently. The devices and methods may provide a base with a removable head, and adapted for partial or complete separation of the irrigation and aspiration functions. The devices and methods can be configured to aspirate and/or irrigate the nasal and sinus cavities. The devices and methods may be manually and/or automatically controlled. The devices and methods may include removable, and/or replaceable, and/or refillable, and easily cleanable reservoirs for aspirant and irrigant. The device head and/or aspirant reservoir may comprise a diagnostic device, i.e., test device and/or container after use of the devices and methods.
