Intended Use

The CyberKnife® Robotic Radiosurgery System is intended to provide treatment planning and image-guided stereotactic radiosurgery and precision radiotherapy for tumors, lesions and conditions anywhere in the body when radiation treatment is indicated.

Device Story

CyberKnife Robotic Radiosurgery System is a computer-controlled medical device for stereotactic radiosurgery and precision radiotherapy. System components include a linear accelerator mounted on a robotic manipulator and a target-locating subsystem. Input data consists of medical images used for treatment planning and real-time tracking signals. The device employs multiple tracking modalities—skull, fiducial, Xsight Spine, Xsight Lung, and Synchrony Respiratory tracking—to dynamically position and point the linear accelerator at the treatment target. Used in clinical settings by specialized medical personnel to deliver precise radiation doses to tumors or lesions. Output is the delivery of therapeutic radiation. Benefits include high-precision targeting of lesions throughout the body, allowing for accurate dose delivery while sparing surrounding healthy tissue.

Clinical Evidence

No clinical data provided; substantial equivalence is based on technological characteristics and intended use.

Technological Characteristics

Computer-controlled robotic system featuring a linear accelerator, robotic manipulator, and integrated target-locating subsystem. Employs multiple tracking technologies (skull, fiducial, Xsight Spine, Xsight Lung, Synchrony Respiratory) for dynamic positioning. Class II medical charged-particle radiation therapy system.

Indications for Use

Indicated for treatment planning, image-guided stereotactic radiosurgery, and precision radiotherapy for lesions, tumors, and conditions anywhere in the body where radiation therapy is clinically indicated.

Regulatory Classification

Identification

A medical charged-particle radiation therapy system is a device that produces by acceleration high energy charged particles (e.g., electrons and protons) intended for use in radiation therapy. This generic type of device may include signal analysis and display equipment, patient and equipment supports, treatment planning computer programs, component parts, and accessories.

#### Device Name

Trade Name: CyberKnife® Robotic Radiosurgery System Classification Name: Medical charged particle radiotherapy device

#### Device Description

The CyberKnife Robotic Radiosurgery System is a computer controlled medical system for planning and performing stereotactic radiosurgery and precision radiotherapy using a linear accelerator, manipulator (robot), and a target locating subsystem to accurately deliver radiation to the treatment target. The CyberKnife System uses skull tracking, fiducial tracking, Xsight™ Spine Tracking, Xsight™ Lung Tracking, and Synchrony™ Respiratory Tracking for dynamic positioning and pointing of the linear accelerator.

## Intended Use

The CyberKnife Robotic Radiosurgery System is intended to provide treatment planning and image-guided stereotactic radiosurgery and precision radiotherapy for tumors, lesions and conditions anywhere in the body when radiation treatment is indicated.

#### Substantial Equivalence

The CyberKnife Robotic Radiosurgery System is substantially equivalent to the predicate device. The intended use, principles of operation, technological characteristics and labeling are the same or equivalent.

#### Dear Ms. Schlagenhaft:

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 (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. 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.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such 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.

Image /page/1/Picture/10 description: The image shows a logo with the letters FDA in a stylized font. Above the letters, the numbers 1906-2006 are visible, indicating a centennial celebration. The word Centennial is written below the letters. The logo is surrounded by a circular border with small stars and text, creating a seal-like appearance.
