Intended Use

This submission describes a system intended for use with a linear accelerator in Radiation Therapy(RT)/stereotactic Radiosurgery(RS) to position a patient relative to the isocenter of the linear accelerator and to monitor the patient's location relative to that position.

Device Story

System uses high-resolution optical camera array and illuminator to track optical markers attached to patient; determines and monitors patient position/orientation relative to linear accelerator treatment isocenter. Components include optical camera array, computer workstation, optical positioning device, and optical calibration device. Used in radiation therapy/stereotactic radiosurgery clinical settings. Provides real-time spatial data to clinicians to ensure accurate patient alignment during treatment. Benefits include improved precision in patient positioning, potentially enhancing radiation delivery accuracy.

Clinical Evidence

No clinical data. Bench testing only.

Technological Characteristics

High-resolution optical tracking system; optical camera array and illuminator; computer workstation; optical positioning/calibration devices. Materials are USP classified for skin contact or 510(k) cleared. System is standalone workstation-based.

Indications for Use

Indicated for patients undergoing radiation therapy or stereotactic radiosurgery requiring positioning and monitoring relative to a linear accelerator isocenter.

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.

#### 510(k) Summary

# Navigator Patient Head/Neck Positioning and Position Monitoring System

#### 5. System Description

The Navigator System utilizes a high resolution optical tracking system to determine and monitor the position of optical markers attached to the patient as the means to locate and monitor the position and orientation of the patient, relative to treatment isocenter.

The Navigator System consists of the following major components:

- a. A high resolution optical camera array and illuminator.
- b. A computer workstation.
- c. An optical positioning device.
- d. An optical calibration device.

#### 6. Performance Standards

Performance standards for this type of system have not been established by the FDA under Section 514 of the Food, Drug, and Cosmetic act.

#### 7. Biocompatibility

The materials used in system components that contact the patient are USP classified for skin contact or 510(k) cleared. These materials have a long history of safe use in dental applications. Their use in this system does not raise any new issues related to safety and effectiveness.

#### 8. Summary of Substantial Equivalence

This system is similar in design, construction, materials, intended use, and performance characteristics to the predicate devices. No new issues of safety or effectiveness are introduced by using this system.

Dated: June 9, 2005 Received: June 10, 2005

Dear Mr. Spotten:

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.
