Abstract:
1. A method of delivering pharmaceutical product comprising the operations of: depositing a pharmaceutical product across a plurality of driver elements and a plurality of acoustic lenses that focuses acoustic energy from the plurality of drivers, the distance from a top surface of the plurality of acoustic lenses to a top surface of the pharmaceutical product being less than 150 micrometers, the plurality of driver elements including at least two drive elements; positioning the plurality of driver elements within four inches of a human orifice; delivering electrical power to the plurality of driver elements causing the plurality of driver elements to deliver acoustic energy to the pharmaceutical product, at least one driver element in the plurality of driver elements coupled to a plurality of lenses such that when the at least one driver element is energized, the acoustic energy from the at least one driver element is received by a plurality of acoustic lenses, each lens approximately focuses a portion of the acoustic energy at a pharmaceutical and air interface to cause approximately simultaneous ejection of droplets of pharmaceutical product into the human orifice.
