The ACUSON Freestyle™ Utrasound System is intended for diagnostic imaging or fluid flow analysis of the human body including: Fetal. Abdominal, Intraoperative Neurological, Pediatric, Small Organ. Neonatal Cephalic. Cardiac, Peripheral Vessel, Musculoskeletal (Conventional), Musculoskeletal Superficial.

Device Description

The ACUSON Freestyle™ Ultrasound System is an ultrasound imaging system, which operates with linear, curvilinear, array transducers. The transducers may be used in either a wireless or wired configuration through a cable connected to the system.

AI/ML Overview

The provided text is a 510(k) summary for the ACUSON Freestyle™ Ultrasound System, detailing its substantial equivalence to previously cleared predicate devices. It focuses on the device's technical characteristics, intended use, and compliance with various safety standards.

However, the document explicitly states that "clinical data is not required for substantial equivalence." This means it does not contain information about specific acceptance criteria related to device performance in a clinical setting, nor does it describe a study that proves the device meets such criteria.

Therefore, I cannot provide the information requested in your prompt regarding acceptance criteria and performance studies, including sample size, data provenance, ground truth establishment, or multi-reader multi-case studies, because this type of clinical performance data is not present in the provided text.

The document mainly focuses on comparing the new device's technical specifications and intended uses to those of predicate devices to demonstrate substantial equivalence, rather than providing performance metrics from clinical trials.

Dear Mr. Job:

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.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Division of Industry and Consumer Education at its toll-free number (800) 638 2041 or (301) 796-7100 or at its Internet address

http://www.fda.gov/MedicalDevices/Resourcesfor You/Industry/default.htm. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to

http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm for the CDRH's Office of Surveillance and Biometrics/Division of Postmarket Surveillance.

Non-clinical Tests submitted, referenced, or relied on for determination of substantial equivalence

The devices have been evaluated for acoustic output, biocompatibility, cleaning and disinfectiveness as well as thermal, electrical, electromagnetic and mechanical safety and to conform with applicable medical devices safety standards. The systems comply with the following standards:

· AAMI/ANSI 60601-1: Medical Electrical Equipment Part 1 General Requirements for Basic Safety and Essential Performance
· IEC 60601-1-2: Medical Electrical Equipment Part 1-2: General Requirements for Basic Safety and Essential Performance: Electromagnetic Compatibility
· IEC 60601-2-37: Medical Electrical Equipment Part 2-37 For Basic Safety and Essential Performance of Ultrasonic Medical Diagnostic Monitoring Equipment
IEC 62366: Medical Devices Application of Usability .
IEC 62304: Medical Device Software Software Life Cycle Process .
NEMA UD-2: Acoustic Output Measurement Standard for Diagnostic Ultrasound ●
NEMA UD-3: Standard for Real-Time Display of Thermal and Mechanical Acoustic Output Indices on Diagnostic Ultrasound Equipment
· ISO 10993-1: Biological Evaluation of Medical Devices

Summary discussion of the clinical tests submitted, referenced, or relied on for determination of substantial equivalence

The ACUSON Freestyle™ Ultrasound System is a class II device, and uses the same technology and operating principle as the predicate devices; clinical data is not required for substantial equivalence.

Conclusion

As shown by the substantial equivalence table above, the ACUSON Freestyle™ is substantially equivalent as the predicate devices; Penrith Elettra Ultrasound System (K100598) and the ACUSON S2000 (K152369).

Regulation Number and Section

§ 892.1550 Ultrasonic pulsed doppler imaging system.

(a)
Identification. An ultrasonic pulsed doppler imaging system is a device that combines the features of continuous wave doppler-effect technology with pulsed-echo effect technology and is intended to determine stationary body tissue characteristics, such as depth or location of tissue interfaces or dynamic tissue characteristics such as velocity of blood or tissue motion. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.(b)
Classification. Class II.
