• Submission Type: Traditional
• Regulation: 21 CFR 892.5750
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The unit is intended to be used in: - delivering the intended dose at a specified position; - delivering the radiation in accordance with the selected relationship of the radiation to the patient (fixed or moving beam therapy, beam modifying device, etc.); - delivering the radiation without causing unnecessary risk to the patient, the operator, other persons, or the immediate environment.

Device Story

Cobalt teletherapy system; delivers gamma radiation for cancer treatment. Components include source head, collimator, gantry, main frame, base, controls, and counterweight (pendulum or beamstopper). Operates by directing radiation beams at specified positions relative to patient anatomy (fixed or moving beam therapy). Used in clinical radiation therapy settings by trained healthcare professionals. Design improves upon predicate device via enhanced safety features and increased radiation shielding in the collimator and unit head assembly. Output is controlled radiation dose delivery; facilitates therapeutic cancer treatment.

Clinical Evidence

Bench testing only. Validation performed in compliance with manufacturer product development procedures to demonstrate that the device meets published specifications and performs equivalent to or better than the predicate device.

Technological Characteristics

Radionuclide radiation therapy system; utilizes cobalt source for gamma radiation. Features include source head, collimator, gantry, main frame, base, and counterweight. Incorporates improved radiation shielding in the collimator and unit head assembly compared to the predicate. System is a stationary clinical unit.

Indications for Use

Indicated for the treatment of cancer via gamma radiation delivery in a radiation therapy clinic under the direction of healthcare 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.

Dear Mr. Martell:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). 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 895. A substantially equivalent determination assumes compliance with the Good Manufacturing Practice for Medical Devices: General (GMP) regulation (21 CFR Part 820) and that, through periodic GMP inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at [phone] for Radiology devices, or 594-4613 for Ear, Nose and Throat devices. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at [phone]. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).
