Abstract
A method for delivering drugs into cystic fluid, the method comprising injecting a drug delivery system (DDS) into a cystic fluid space at an injection site, the DDS comprising at least one therapeutic agent encapsulated in biodegradable polymers, applying ultrasonic energy proximal to the injection site, and controlling the at least one of buoyancy, delivery location, mixing, and dispersion of the DDS to a targeted area using the ultrasonic energy.
