The Axxent Balloon Applicator is indicated for use with the Axxent Electronic Brachytherapy System to deliver intracavity or intraoperative brachytherapy wherever the physician chooses to deliver radiation treatment.

Device Description

The Axxent Balloon Applicator is a component of the Axxent Electronic Brachytherapy System, which utilizes a proprietary miniaturized X-ray source and does not require radioactive isotopes. The applicator allows the Axxent HDR Xray Source to deliver intracavitary or intraoperative brachytherapy wherever the physician chooses to deliver radiation treatment. The Axxent HDR X-ray Source mimics the penetration and dose characteristics of Iridium-192 within the treatment target. The Axxent Balloon Applicator is provided in five sizes to ensure proper fit into treatment areas of varying shapes and sizes. The applicators are disposable and provided sterile.

AI/ML Overview

The provided text is a 510(k) premarket notification for the Axxent® Balloon Applicator. It primarily focuses on the regulatory submission and approval process, stating that the device has "No device design changes" and that "The purpose of this submission is only to expand the indications for use of the Axxent Balloon Applicator to deliver intracavitary or intraoperative brachytherapy wherever the physician chooses to deliver radiation treatment."

Critically, the document does not describe any new study proving device performance or establishing acceptance criteria. Instead, it relies on the substantial equivalence to a previously approved predicate device (K050843) and its existing technological characteristics.

Therefore, I cannot provide the requested table and study information because the provided text does not contain any new acceptance criteria or details of a study conducted to prove the device meets new acceptance criteria. The submission is purely about expanding the indications for use based on the previous approval.

To answer your request, a new study would need to have been conducted, and the details of that study, including acceptance criteria and performance data, would need to be present in the document.

Device Description

Note: No device design changes. The purpose of this submission is only to expand the indications for use of the Axxent Balloon Applicator to deliver intracavitary or intraoperative brachytherapy wherever the physician chooses to deliver radiation treatment.

The Axxent HDR X-ray Source mimics the penetration and dose characteristics of Iridium-192 within the treatment target. The Axxent Balloon Applicator is provided in five sizes to ensure proper fit into treatment areas of varying shapes and sizes. The applicators are disposable and provided sterile.

Intended Use

The Axxent Electronic Brachytherapy System is intended to deliver high dose rate X-ray radiation for brachytherapy.

Summary of the Technological Characteristics

No device design changes. The technological characteristics of the Axxent Balloon Applicator are the same as the Axxent Balloon Applicator approved under K050843. The device is substantially equivalent in terms of design, materials, principles of operation, and product specification to the predicate device. A comparison table is available in Tab 8.

Dear Mr. Lin:

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). You may, therefore, market the device, subject to the general controls provisions of the Act and the limitations described below. 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.

The Office of Device Evaluation has determined that there is a reasonable likelihood that this device will be used for an intended use not identified in the proposed labeling and that such use could cause harm. Therefore, in accordance with Section 513(i)(1)(E) of the Act, the following limitation must appear in the Warnings device's labeling:

The Safety and effectiveness of the Axxent Electronic Brachytherapy System as a replacement for whole breast irradiation in the treatment of breast cancer has not been established.

Please note that the above labeling limitations are required by Section 513(i)(1)(E) of the Act. Therefore, a new 510(k) is required before these limitations are modified in any way or removed from the device's labeling.

{3}------------------------------------------------

The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and permits your device to proceed to the market. This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification if the limitation statement described above is added to your labeling.

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