  • METHODS AND SYSTEM FOR SELECTIVE AND LONG-TERM NEUROMODULATION USING ULTRASOUND
    Publication number: 20210353967
    Abstract: Specific parameter sets are provided that makes the transcranial focused ultrasound to selectively activate a certain neuronal type at cortical brain and enables the transcranial focused ultrasound to non-invasively induce long-term effects at deep brain. A type of ultrasound collimator with incidence angle control is designed and validated through acoustic field pressure mapping in order to target brain areas at different depths. Multi-elements transducer arrays are also used to achieve transmission of focused ultrasound.

  • THERAPEUTIC ULTRASOUND TRIGGERED SILK FIBROIN SCAFFOLD DEGRADATION
    Publication number: 20210228773
    Abstract: A method and apparatus for degrading a hypodermal tissue scaffold involves exposing the scaffold to a low-intensity focused ultrasonic beam such as to induce transient cavitation of microbubbles trapped in the hydrophobic domains of the silk fibroin from which scaffold is constructed. In one embodiment, the ultrasonic beam is a 1 MHz pulsed signal having a period of approximately 500 ms. The weight reduction experienced by the scaffold as a function of the exposure time of the scaffold to the ultrasonic beam.
