Methods and devices for modulating cellular activity using ultrasound
First Claim
1. A method for modulating neuronal cellular activity of a neuronal cellular site in a subject, comprising:
- (i) acoustically coupling at least one component for generating ultrasound waves to an external surface of the subject, and(ii) driving the at least one component for generating ultrasound waves to form at least one stimulus waveform at the neuronal cellular site, the stimulus waveform comprising a plurality of pulses, each pulse of the plurality comprising a plurality of acoustic cycles having a plurality of frequencies in a range from about 0.02 to about 100 MHz at the site of the cells to be modulated, wherein pulses of the plurality are repeated to produce spatial-peak temporal-average intensities of no more than 100 W/cm2 to modulate neuronal cellular activity at the neuronal cellular site.

Abstract
The present invention comprises methods and devices for modulating the activity or activities of living cells, such as cells found in or derived from humans, animals, plants, insects, microorganisms and other organisms. Methods of the present invention comprise use of the application of ultrasound, such as low intensity, low frequency ultrasound, to living cells to affect the cells and modulate the cells'"'"' activities. Devices of the present invention comprise one or more components for generating ultrasound waves, such as ultrasonic emitters, transducers or piezoelectric transducers, composite transducers, CMUTs, and which may be provided as single or multiple transducers or in an array configurations. The ultrasound waves may be of any shape, and may be focused or unfocused.
