Methods of soft tissue emulsification using a mechanism of ultrasonic atomization inside gas or vapor cavities and associated systems and devices

摘要

The present technology is directed to methods of soft tissue emulsification using a mechanism of ultrasonic atomization inside gas or vapor cavities, and associated systems and devices. In several embodiments, for example, a method of non-invasively treating tissue includes pulsing ultrasound energy from the ultrasound source toward the target site in tissue. The ultrasound source is configured to emit high intensity focused ultrasound (HIFU) waves. The target site comprises a pressure-release interface of a gas or vapor cavity located within the tissue. The method continues by generating shock waves in the tissue to induce a lesion in the tissue at the target site. The method additionally includes characterizing the lesion based on a degree of at least one of a mechanical or thermal ablation of the tissue.

1. A method of non-invasively treating tissue, the method comprising:
pulsing ultrasound energy from an ultrasound source to a target site in tissue, wherein the ultrasound source is configured to emit high intensity focused ultrasound (HIFU) waves, and wherein the target site comprises a pressure-release interface located between tissue and a gas or vapor cavity; generating shock waves in the tissue to induce a lesion in the tissue at the target site; atomizing the tissue at the pressure-release interface to create an acoustic fountain; and characterizing the lesion based, at least in part, on a degree of at least one of a mechanical or thermal ablation of the tissue at the target site.
