Intended Use

The Rotating Gamma System, GammaART 6000 is a tele-therapy radiation treatment device intended to be used for stereotactic irradiation of intracranial structures. The device is to be used by licensed medical professionals, having been trained in the use and safety precautions of this device.

Device Story

The GammaART 6000 is a tele-therapy system for intracranial radiosurgery. It utilizes 30 Cobalt-60 sources mounted on a hemispheric carrier. A secondary collimator assembly acts as a radiation shutter; when active, it aligns sources to a prescribed collimator size. The source unit and collimator rotate as a single unit to form 30 non-overlapping 360-degree arcs, providing high focal dose uniformity and small penumbra. The system was modified to replace an ACS SB214ND 4-axis motion controller with a Galil DMC-2000 5-axis motion controller. Operated by trained medical professionals in a clinical setting, the device delivers precise radiation to intracranial targets. The output is a focused radiation dose, which aids clinicians in treating selected intracranial abnormalities.

Clinical Evidence

No clinical data provided. The submission is a Special 510(k) for a component modification (motion controller) to a previously cleared device.

Technological Characteristics

Tele-therapy device; 30 Cobalt-60 sources; hemispheric shielded source carrier; secondary collimator assembly; 5-axis motion controller (Galil DMC-2000); 360-degree arc rotation; high focal dose uniformity.

Indications for Use

Indicated for stereotactic irradiation of intracranial structures in patients requiring radiation treatment, to be administered by trained licensed medical professionals.

Regulatory Classification

Identification

A radionuclide radiation therapy system is a device intended to permit an operator to administer gamma radiation therapy, with the radiation source located at a distance from the patient's body. This generic type of device may include signal analysis and display equipment, patient and equipment supports, treatment planning computer programs, component parts (including beam-limiting devices), and accessories.

Predicate 510(k) Number K970647

## Description:

2.

This 510(k) Special Submission if for a modification to cleared K970647 Rotating Gamma System that has received a motion controller upgrade. The ACS SB214ND 4axis motion controller (P/N: D-000024) has been replaced with the new Galil DMC-2000 5-axis motion controller (P/N: C-000141).

## Basis for Submission:

The replacement of the RGS 6000 motion controller is a "control mechanism change" as specified by question B1 of the 510(k) Memorandum #K97-1 from the United States Food and Drug Administration, Office of Device Evaluation dated January 10, 1997. As this change can potentially "raise new issues of safety and effectiveness" (question B.8.3 from the FDA Guidance), a Special 510(k) has been submitted.

## Intended use:

The Rotating Gamma System, GammaART 6000 is intended to be used by licensed Medical Professionals for radiation treatment of selected intracranial abnormalities. previously cleared for the OUR Rotating Gamma System and the Leksell Gamma Knife.

## Summary of technological characteristics:

Special 510(k) Summary

The Rotating Gamma System, GammaART 6000 is a tele-therapy device which contains 30 Cobalt-60 sources distributed on a hemispheric shielded source carrier. Inside the source unit is the "built in" secondary collimator which has four sides of collimators and one block position. When not treating, all sources are aligned with the block position of the secondary collimator, which in this case acts as a radiation shutter. Treatment starts with aligning the sources to the prescribed collimator size, then both the source unit and the secondary collimator rotate as one unit. By rotating the Cobalt-60 sources, 30 nonoverlapping full 360 degree arcs are formed, resulting in high focal dose uniformity and small focal spot penumbra.

Dear Mr. Olivier:

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.
