Intended Use
The Varian Head Frame System is for use with a computed tomography scanner to perform imaging for treatment planning and a charged particle accelerator to perform immobilization of the treatment target for stereotactic radiosurgery or radiotherapy treatments on cranial lesions, tumors and conditions where radiation treatment is indicated.
Device Description
The Head Frame provides rigid immobilization of a patient's skull by attaching a rigid halo (head frame) to the patient through four invasive contact points (called screws or pins) which penetrate the patient's skin and contact the bone of the skull. The head frame is secured to either the CT table or the treatment table via a bracket which is included in the system. This ensures the patient cannot easily move during imaging or treatment. This level of immobilization is generally used for stereotactic radiosurgery.
More Information

Not Found

No
The device description focuses solely on mechanical immobilization and does not mention any software, algorithms, or data processing that would suggest the use of AI or ML. The "Mentions AI, DNN, or ML" and "Mentions image processing" sections are explicitly marked as "Not Found".

No
The device is used for immobilization during imaging and radiation treatment, not for providing therapy itself.

No

The Varian Head Frame System is used for immobilization during imaging and treatment; it does not perform a diagnostic function itself.

No

The device description explicitly details physical hardware components (rigid halo, screws/pins, bracket) used for patient immobilization, which are not software.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health. These tests are performed outside the body (in vitro).
  • Device Function: The Varian Head Frame System is a physical device used for immobilization of a patient's head during imaging and radiation treatment. It directly interacts with the patient's body (invasively) to hold them still.
  • Intended Use: The intended use is for immobilization during imaging and treatment planning, and for immobilization during the treatment itself. It does not involve analyzing biological samples.

The description clearly indicates a device used on the patient for physical support and positioning, not for analyzing samples taken from the patient.

§ 892.5050 Medical charged-particle radiation therapy system.

(a)
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.(b)
Classification. Class II. When intended for use as a quality control system, the film dosimetry system (film scanning system) included as an accessory to the device described in paragraph (a) of this section, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

Dear Mr. Coronado:

We have reviewed vour 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. 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.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
