Surgery without Knives or Needles

Published on Mar 31, 2016

A team of researchers at the University of Michigan has developed a new, revolutionary technique that has the potential to reshape the practice of surgery. Histotripsy — literally, the “crushing of tissue” — is a noninvasive therapy that uses high-intensity ultrasound pulses to liquify tissue inside the body without ever breaking the skin. With applications from congenital heart defects to brain tumors, Histotripsy will significantly impact quality of life for patients, who will be able to receive it at their physician’s office — potentially at the exact time of diagnosis — without sedation or a lengthy recovery.


Histotripsy, a non-invasive cancer treatment

Michigan Engineering Professor Charles Cain outlines a new technique called “Histotripsy,” which is a non-invasive ultrasonic approach for the treatment of benign disease and cancer. Cain says the knifeless surgical approach generates energetic microbubbles that oscillate very rapidly, almost like a “nano-blender.” The procedure can be used for multiple applications, including treating newborn infants with heart defects, prostate patients and potentially diseases such as breast cancer.

ABOUT THE PROFESSOR: Professor Cain is the Founding Chair of Biomedical Engineering at the University of Michigan and the Richard A. Auhll Professor of Engineering. He and his research team have been developing the histotripsy technique for the last five years.
