Petal Surgical develops a surgical platform that destroys targeted tissue with focused ultrasound instead of an incision, a mechanism it calls Millisecond Pulse Histotripsy. High-intensity sound waves are focused deep inside the body to form a vapor cavity, and a cloud of small bubbles that forms, expands, and collapses in front of it liquefies the cells in the region. The treated region is left as non-viable subcellular debris the body absorbs and eliminates.
Petal differentiates the platform from incisional surgery on mechanism: diseased tissue is liquefied by focused acoustic energy rather than cut, and the company states the approach avoids incisions, heat, and trauma while preserving surrounding tissue and structure. It designs the treatment for hospitals and the clinicians who work in them, with outpatient-ready workflows as its stated operating requirement.
