Intended Use

The Accu-Source™ remote control high dose rate afterloading brachytherapy system is intended for the treatment of cancer and other lesions by intracavitary, interstitial, intralumenal, intraoperative, endobronchial and surface applicator irradiation treatments.

Device Description

The Accu-Source™ is a remote afterloading system for High Dose Rate Brachytherapy. The system is designed to deliver a predetermined dose of radiation to organs and tissue via a radioactive source. The ACCU-SOURCE™ system includes an operator console and a remote afterloading device. The ACCU-SOURCE™ system has a tungsten shielded storage safe which houses a radioactive source when the system is not in use. There are encoders and motors used in conjunction with electronic circuitry that drive the source and keep track of its position. A battery is used for back-up power and an uninterruptible power supply is also integrated into the ACCU-SOURCE™ system to charge the battery backup subsystem.

AI/ML Overview

The provided document is a 510(k) summary for a medical device called Accu-Source™, a Remote Control High Dose Rate Afterloading Brachytherapy Device. This type of submission is for demonstrating substantial equivalence to a predicate device, not for proving the device meets specific acceptance criteria through a formal clinical study with performance metrics as one might see in a de novo or PMA submission.

Therefore, the document does not contain the acceptance criteria and study details as requested in the input prompt (e.g., sample sizes for test/training sets, expert qualifications, adjudication methods, MRMC studies, standalone performance, or ground truth establishment for a diagnostic device).

Instead, it focuses on demonstrating that the Accu-Source™ device is substantially equivalent to a legally marketed predicate device (Nucletron MicroSelectron HDR Version 2). This is done through a comparison of technical specifications, intended use, and general features.

Here's a breakdown of what can be extracted based on the provided text, and what cannot:


1. A table of acceptance criteria and the reported device performance:

  • Acceptance Criteria: Not explicitly stated as "acceptance criteria" in the context of a performance study. However, the implicit acceptance criteria for a 510(k) submission are that the new device is as safe and effective as a predicate device and does not raise new questions of safety or effectiveness. This is demonstrated by showing similar specifications and performance characteristics to the predicate.
  • Reported Device Performance: The document provides a comparison table of technical specifications between the Accu-Source™ and its predicate, the Nucletron MicroSelectron HDR Version 2. This table highlights features, intended use, and various physical and operational parameters. The "performance" here is described by these specifications, rather than quantitative metrics from a clinical study.

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):

  • Not Applicable: The document does not describe a clinical performance study with a test set of data. It is a comparison of technical specifications against a predicate device.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

  • Not Applicable: No clinical performance study or ground truth establishment is described for a test set.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

  • Not Applicable: No clinical performance study or adjudication is described.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

  • Not Applicable: This device is a remote afterloading brachytherapy system, not an AI-assisted diagnostic tool involving human readers.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

  • Not Applicable: This device is a physical brachytherapy system, not solely an algorithm. Its performance is demonstrated through its physical and operational specifications.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):

  • Not Applicable: The concept of "ground truth" for a performance study is not relevant in this 510(k) submission, which focuses on substantial equivalence based on technical specifications and safety features.

8. The sample size for the training set:

  • Not Applicable: No machine learning or algorithm development with a training set is described.

9. How the ground truth for the training set was established:

  • Not Applicable: No machine learning or algorithm development with a training set is described.

In summary: The provided 510(k) summary for the Accu-Source™ device establishes substantial equivalence by comparing its technical specifications and intended use to a predicate device, rather than through a detailed clinical or diagnostic performance study that would typically involve acceptance criteria, test/training sets, expert ground truth, or MRMC studies.

Dear Ms. Williams:

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.

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); 200d manufacturing practice requirements as set forth in the quality systems (05) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act): 21 CFR 1000-1050.

{5}------------------------------------------------

This letter will allow you to begin marketing your device as described in your Section 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), please contact the Office of Compliance at one of the following numbers, based on the regulation number at the top of this letter:

21 CFR 876.xxxx(Gastroenterology/Renal/Urology)240-276-0115
