ZAP Surgical announces the installation of its pioneering radiosurgery platform at the Japanese bullet train station


SAN CARLOS, Calif.–(BUSINESS WIRE)–ZAP Surgical Systems, Inc. today announced the installation of its first ZAP-X® Gyroscopic Radiosurgery® platform in Japan. Using a new vaultless design that typically eliminates the need for expensive shielded radiation rooms, the new ZAP-X is located in the newly redeveloped Utsunomiya Bullet Train Station in Tochigi Prefecture, Japan. Operated by the Utsunomiya Neurospine Center Symphony Hospital, the site will offer non-invasive outpatient treatments for many brain tumors that once required invasive surgery.

Stereotactic radiosurgery (SRS) is a well-studied treatment for many primary and metastatic brain tumors. Compared to conventional surgery, radiosurgery can provide equivalent and superior clinical outcomes, while offering eligible patients a painless procedure with no anesthesia, no incisions, and often no recovery period. Despite the benefits, the significant radiation shielding costs and infrastructure requirements of previous generation SRS systems have limited widespread access to this potentially life-saving therapy.

Leveraging technological innovations that for the first time are making dedicated radiosurgery feasible outside of large teaching hospitals, this installation of the ZAP-X platform marks a significant step forward in bringing world-class SRS to patients. millions of potential patients who currently do not have access to it.

“With approximately 24-45% of cancer patients developing brain metastases during their disease, ZAP-X now allows us to bring the most advanced SRS technology to a significant patient population – a population that continues to grow. , particularly due to cancer survival rates are improving,” said Professor Phyo Kim, MD, PhD, ZAP-X program manager at the Utsunomiya Neurospine Center and former senior professor of neurosurgery at the University Dokkyo “By bringing advanced radiosurgery into a convenient and entirely new setting outside of the large urban hospital, we look forward to working with ZAP to make SRS accessible to more patients in more places.”

“Utsunomiya’s new facility ushers in a new era of patient access and convenience to the SRS, where patients from near and far will be treated cost-effectively, without having to enter Tokyo’s congested downtown or a crowded remote hospital,” said Dr. John Adler, CEO and Founder of ZAP Surgical, and Dorothy & TK Chan Professor Emeritus of Neurosurgery and Radiation Oncology at Stanford University.

Utilizing a distinctive gyroscopic design, ZAP-X delivers hundreds of uniquely angled ionizing beams to precisely sculpt radiation to the unique contours of the tumor. Through this unique approach, ZAP-X supports the clinical goal of protecting surrounding healthy brain tissue and patient neurocognitive function. Additionally, by significantly reducing the incident radiation dose to the body compared to other general-purpose radiation delivery systems, ZAP-X seeks to set new standards in patient safety.

ZAP-X is also recognized for being the first and only dedicated SRS platform to no longer require the hosting of volatile radioactive isotopes in the clinical setting.

It is estimated that the first treatments for patients at the Utsunomiya Neurospine Center will begin in early 2022.

ZAP-X received Japanese Shonin Clearance in April 2020. To learn more about the ZAP-X Gyroscopic Radiosurgery Platform, please visit: Detailed system overview animations are available at (English) and (Japanese).

About Utsunomiya Neurospina Center

The Utsunomiya Neurospine Center Symphony Clinic, inaugurated in December 2021, offers comprehensive neurological and neurosurgical services, including related specialties, such as orthopedics, neuro-otology, neuro-urology and pediatric neuro-endocrinology. It provides surgical treatments encompassing specialties of spinal, vascular, endovascular, tumor and functional neurosurgery as well as stereotactic radiosurgery using ZAP-X. The hospital is built as part of a complex (Symphony Project) consisting of a convention center, offices, a commercial building and hotels. It adjoins a high-speed train station, which reaches central Tokyo in 50 minutes. The terminal also serves classic local lines and a new tram line.
