Low-Frequency Ultrasound (MIST)
MIST Ultrasound
A gentle, painless mist of sound waves that helps clean and heal slow wounds.
What it does
MIST therapy uses a fine saline mist with low-frequency sound waves to clean the wound bed without touching it. It's especially helpful for wounds that are too painful for traditional cleaning, or that aren't progressing as expected.
