AI/ML (Artificial Intelligence / Machine Learning)

No
The summary describes a standard ultrasound system with basic imaging and measurement capabilities, and there is no mention of AI or ML in the device description, intended use, or specific sections for AI/ML details.

Therapeutic

No
The device is described as a diagnostic ultrasound system used for imaging and measurement, not for treatment.

Diagnostic

Yes
The device description explicitly states, "The SIUI CTS-5500/CTS-6600 is a portable diagnostic ultrasound system."

SaMD (Software as a Medical Device)

No

The device description explicitly states it consists of probes, a main unit, a control panel, and a monitor, which are all hardware components.

IVD (In Vitro Diagnostic)

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

Here's why:

• IVD devices are used to examine specimens obtained from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
• This device is an ultrasound system. Ultrasound uses sound waves to create images of internal organs and structures within the body. It does not analyze samples taken from the body.

The intended use and device description clearly indicate it's an imaging device for visualizing internal anatomy, not for testing biological samples.

Dear Mr. Leiker:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and we 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. 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.

This determination of substantial equivalence applies to the following transducers intended for use with the CTS-5500/CTS-6600 Diagnostic Ultrasound Imaging System, as described in your premarket notification:

Image /page/2/Picture/11 description: The image is a circular seal with the letters "FDA" in the center. The text "The New FDA Centennial" is arranged around the top and bottom of the circle. The seal is surrounded by a dotted border.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), 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); 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.

This determination of substantial equivalence is granted on the condition that prior to shipping the first device, you submit a postclearance special report. This report should contain complete information, including acoustic output measurements based on production line devices, requested in Appendix G, (enclosed) of the Center's September 30, 1997 "Information for Manufacturers Seeking Marketing Clearance of Diagnostic Ultrasound Systems and Transducers." If the special report is incomplete or contains unacceptable values (e.g., acoustic output greater than approved levels), then the 510(k) clearance may not apply to the production units which as a result may be considered adulterated or misbranded.

The special report should reference the manufacturer's 510(k) number. It should be clearly and prominently marked "ADD-TO-FILE" and should be submitted in duplicate to:

Food and Drug Administration Center for Devices and Radiological Health Document Mail Center (HFZ-401) 9200 Corporate Boulevard Rockville, Maryland 20850

This letter will allow you to begin marketing your device as described in your 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 market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at [phone]. Also, please note the regulation entitled. "Misbranding by reference to premarket notification" (21CFR Part 807.97). You may obtain other general information on your responsibilities under the Act from the Division of Small
