Methods and systems for delivering fluids, aerosols, and/or acoustic energy to target sites on tissue surfaces and within body cavities or lumens, obstructions or undesired materials associated with body cavities and tissue surfaces and, particularly, target sites on tissue surfaces or at obstructions within natural orifices, such as ear, nose and throat passages and, particularly, nasal passages and cavities, are provided. In one aspect, methods and systems for delivering fluids and/or aerosols to target sites such as nasal passages at generally high frequency (e.g., sonic and ultrasound) pulsation rates and at multiple, alternating pulsation rates are provided. |
