Making healing human.

Surgery that doesn’t cut.

Petal is redefining surgery with an intricate interplay of precisely directed sound waves with diseased cells. Our platform uses Acoustic Liquefaction - focused acoustic energy to break down targeted tissue without incisions, heat, or trauma enabling the body to heal itself naturally.

It’s time.

At Petal, we believe healing should never begin with harm.

We’re pioneering a new kind of surgery. One that doesn’t cut.

Rooted in science. Built for human dignity.

It’s time, to make healing human.

How does Acoustic Liquefaction work?

A new class of focused therapeutic ultrasound that delivers precise, controlled tissue manipulation without incisions, heat, or toxicity.

Targeting

Precisely controlled high intensity sound waves are focused deep inside the body to form a single, predictable vapor cavity.

Treatment

A cloud of small bubbles forms, expands, and collapses in front of the vapor filled cavity, liquefying all the cells in the region.

Removal

The liquefied region is left with non-viable subcellular debris that is naturally absorbed and eliminated by the body.

What industry leaders are saying:

  • "I am extremely excited about the clinical capabilities of boiling histotripsy and its ability to deliver touchless surgical intervention in the future."

    Frederic H Moll, MD

    Founder of Intuitive Surgical


  • “Surgery has long been the standard for treating life-threatening disease, but even with advances like robotics and radiation, complications still occur in over 20% of procedures prolonging recovery and increasing costs. The idea of offering curative therapy without cutting into the body once felt like science fiction. But with Petal’s technology, that vision is becoming reality. Imagine leaving the doctor’s office minutes after treatment and returning to life the same day."

    Sal Brogna

    Led development of the da Vinci product line at Intuitive Surgical.

  • “Progress in medicine is often slow and silent. Now, that progress has sound - through the harnessing of acoustic energy in histotripsy - to target tumors deep within the body without risking injury to nearby tissue, as current surgery often does. The promise of incisionless surgery is here, and Petal will change the way we treat patients going forward."

    Dr. Nicholas Theodore
