No
The summary describes standard ultrasound transducers and their technical specifications. There is no mention of AI, ML, image processing beyond basic ultrasound functionality, or any data sets for training or testing, which are typical indicators of AI/ML integration in medical devices.

No
The device is described as "intended for diagnostic ultrasound imaging or fluid flow analysis", which are diagnostic, not therapeutic, applications.

Yes
The "Intended Use / Indications for Use" section explicitly states that the transducers "are intended for diagnostic ultrasound imaging or fluid flow analysis of the human body."

No

The device description clearly outlines physical specifications for transducers, which are hardware components of an ultrasound system.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is "diagnostic ultrasound imaging or fluid flow analysis of the human body." This describes a device that interacts with the body externally to produce images or analyze flow, not a device that analyzes samples taken from the body (which is the core of an IVD).
  • Device Description: The description details the technical specifications of ultrasound transducers, which are components of an ultrasound system used for imaging.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), reagents, or any processes typically associated with in vitro diagnostics.

Therefore, this device falls under the category of a medical imaging device, not an IVD.

(a)
Identification. A diagnostic ultrasonic transducer is a device made of a piezoelectric material that converts electrical signals into acoustic signals and acoustic signals into electrical signals and intended for use in diagnostic ultrasonic medical devices. Accessories of this generic type of device may include transmission media for acoustically coupling the transducer to the body surface, such as acoustic gel, paste, or a flexible fluid container.(b)

6. BASIS FOR SUBSTANTIAL EQUIVALENCE

The TETRAD Model TC-EC7-ACP, -L5-, -L7-, -V4-ACP Transducers are substantially equivalent to the corresponding Acuson products which are currently in commercial distribution in the United States, since the subject devices are functionally similar and have the same intended uses as the corresponding predicate transducers. The only substantive differences being the following points that were determined during the clearance of the TC-C3-ACP (an equivalent to the Acuson C3 Transducer) under K002193.

  • . The TETRAD Transducers are not intended for Fetal Doppler applications on the Acuson 128XP (a Track 1 device).
  • The acoustic output levels of the TETRAD Transducers are equal . to or slightly lower than those of their respective corresponding Acuson Transducers.

Dear Mr. Job:

We have reviewed your Section 510(k) premarket notification of intent to market the device we have to rearly 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 mendments, 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 the general vontrols pro risens or on, 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 rins decemination of backland 24XP Diagnostic Ultrasound Systems as described in your premarket notification:

Transducer Model Number

TC-L7-ACP
TC-L5-ACP
TC-EC7-ACP
TC-V4-ACP

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. may pacined 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 or any I 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 (301) 594-4591. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or at (301) 443-6597 or at its Internet address "http://www.fda.gov/cdrh/dsmamain.html".
