HistoSonics, developer of a non-invasive robotic platform and sonic beam therapy, announced today that it has closed $40 million in an oversubscribed Series C-1 financing. The round was led by Yonjin Venture, LLC, who specializes in innovative early and mid-stage life science companies, and included additional new strategic investors. Also participating were existing investors Varian Medical Systems, Inc., Johnson & Johnson Innovation - JJDC, Inc. (JJDC), Venture Investors, Lumira Ventures, State of Wisconsin Investment Board, and others. The financing will be used to accelerate activities focused on the Company's Edison™ Platform, as well as launch new strategic projects.

HistoSonics' Edison Platform uses advanced imaging and proprietary sensing technology to deliver non-invasive, personalized treatments with unparalleled precision and control, and uses the science of histotripsy and focused sound energy to generate pressures strong enough to liquify and completely destroy targeted tissues at sub-cellular levels. The company believes that the novel mechanism of action of their proprietary technology provides significant advantages to patients, including the ability of the treatment site to recover and heal quickly, as well as provides physicians the unique ability to monitor the destruction of tissue under continuous real-time visualization and control, unlike any modality that exists today.

"We believe that having the ability to precisely destroy targeted tissue without entering the body and without the use of radiation or thermal energy, will provide meaningful change to patients and the physicians who care for them." said Mr. Wen Chen, Venture Partner at Yonjin Venture.

"We believe that histotripsy and the Edison Platform have the ability to provide meaningful clinical,
