Dear Lynn Allman:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

glomus tumors, and hemangiomas), metastasis (including all parts of the body such as brain, bone, liver, lung, kidney, and skin), pediatric tumors (such as glioma, ependymoma, pituitary tumors, hemangioblastoma, craniopharyngioma, meningioma, metastasis, medulloblastoma, nasopharyngeal tumors, arteriovenous malformation, cavernous malformation, and skull base tumors), and low-dose radiotherapy for adults with medically refractory osteoarthritis.

The modification to the Indications for use do not change the Intended Use of the device, as the general purpose of the device and its function remain the same. Additionally, the intended therapeutic use of the device remains the same - "to provide stereotactic radiosurgery and precision radiotherapy for lesions, tumors, and conditions anywhere in the body where radiation treatment is indicated." As demonstrated by the risk management activities per ISO 14971, the differences do not affect the safety and effectiveness of the device when used as labeled.

## COMPARISON OF TECHNOLOGICAL CHARACTERISTICS

Both subject device and the predicate device contain the same technological characteristics and functional scientific technology to deliver radiation therapy and stereotactic radiosurgery by authorized medical practitioners. The Intended Use is unchanged. There are no changes in the principle of operation of the device. The biocompatibility of patient-contacting components remains the same as the predicate device. The results of the verification, validation and safety standards testing demonstrates that there are no changes to the safety profile of the device.

Both the predicate device and the subject device are based on the same characteristics:

Both the subject device and the predicate device configurations use the same medical linear accelerator (linac) to deliver stereotactic radiosurgery and precision radiotherapy and support the same treatment techniques.

- Both devices use the same couch and support the same couch motions.
- Both devices use the same integrated treatment and imaging consoles and support external beam radiation delivery with X-RAY, Electron, and PHOTON beam for SRT/SRS.
- Both devices use the same muti-leaf collimators and support a range of imaging techniques.

The significant difference (based on "Deciding When to Submit a 510(k) for a Change to an Existing Device. (October 2017)") compared to the predicate device is the modification of the indications for use.

Non-significant changes include defect fixes, cybersecurity improvements, and minor hardware changes.
