Tissue fragmentation via ultrasonic cavitation

Tissue fragmentation via ultrasonic cavitation refers to the use of high-frequency ultrasound energy to disrupt biological tissue through the formation, oscillation, and collapse of microbubbles, a phenomenon known as cavitation. These bubbles produce physical forces that fragment tissue at the cellular level, selectively damaging targets like adipocytes in body contouring/liposuction, destroying atherosclerotic plaques, or ablating tumors[1][3][8]. The process is mediated by mechanical (cavitation), thermal (heat), and chemical (free radical generation) effects, with device parameters fine-tuned to target specific tissues while minimizing collateral damage. It is widely used in ultrasonic liposuction, surgical aspirators, and focused ultrasound therapies, but is not a molecular or receptor-based target; it is a physical-chemical method for tissue ablation[5][7][8]. Notable safety concerns include risk of burns, seroma formation, and DNA damage from free radicals[4][7].
