Abstract
A myringotomy device includes a housing; an elongated tube extending from the housing; and a retractable cutting tool extendable through the elongated tube, the cutting tool comprising a blade. The cutting tool is configured such that when advanced, the blade of the cutting tool extends beyond a distal end of the elongated tube. The cutting tool is also configured such that when retracted, the blade is retracted into the elongated tube and a fluid conduit is created from the distal end of the elongated tube to the housing.
