摘要：
A method of delivering a substance includes providing a substance at a location in a gastrointestinal (GI) tract, excluding a buccal membrane, of a biological body and applying ultrasonic waves, having a frequency between about 20 kHz and about 10 MHz, at the location. The method can include storing the substance in at least one reservoir and exposing a medium within or of the GI tract to the substance. The method can further include delivering a device into the GI tract, the device including at least one ultrasound transducer and circuitry powering the at least one ultrasound transducer and circuitry from within the device and driving the at least one ultrasound transducer, using the circuitry, in a manner causing the at least one ultrasound transducer to emit ultrasonic waves to a medium within or of the GI tract.
