The Hitachi Aloka Medical, Ltd UST-5310 or UST-5311 or UST-5311-TIP transducers are intended for use with the PROSOUND ALPHA 6, PROSOUND ALPHA 7 and ARIETTA70 Diagnostic Ultrasound systems by trained personnel (doctor, sonographer, etc.) for the diagnostic ultrasound evaluation during intraoperative and Intra-operative (neurosurgery) procedures.

This device is not indicated for Ophthalmic applications.

Device Description

Linear Array transducer

AI/ML Overview

The provided text is a 510(k) summary for a medical device (ultrasound transducers). It describes the device, its intended use, and compares it to a predicate device to establish substantial equivalence. However, it does not contain information about acceptance criteria or a study that specifically proves the device meets those criteria in the way you've outlined.

The document states:

"No new hazards were identified with the addition of the UST-5311 transducers to the PROSOUND ALPHA7 & ARIETTA70."
"The subject systems and the transducers have been evaluated for acoustic output, biocompatibility, electromagnetic compatibility, as well as electrical and mechanical safety, and have been found to conform to applicable medical device safety standards."
"Clinical testing: None required"

This means the submission relies on demonstrating that the new application (using existing transducers with new ultrasound systems) does not introduce new risks and that the components (transducers and systems) individually meet safety and performance standards. It does not describe a performance study with acceptance criteria in the context of diagnostic accuracy, sensitivity, specificity, etc., which would typically be included for devices that provide diagnostic insights.

Therefore, I cannot provide the answer in the requested format because the necessary information is not present in the provided text. The document is essentially declaring that the existing transducers, when used with modified systems, are still safe and effective as previously determined, without the need for a new study to assess their diagnostic performance against specific acceptance criteria.

Dear Ms. Arsdale:

This letter corrects our substantially equivalent letter of October 16, 2014.

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. 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 (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.
