The description focuses on the physical characteristics of the transducer and its ability to add volume imaging, with no mention of AI or ML algorithms for image processing or analysis.
No
The device description and intended use clearly state that it is for "Diagnostic ultrasound imaging or fluid flow analysis" and for "non-quantitative visualization." It is not described as treating any condition.
Yes
The "Intended Use / Indications for Use" section explicitly states "Diagnostic ultrasound imaging or fluid flow analysis of the human body". The "Device Description" also mentions it is a modification of a transducer "cleared for...diagnostic ultrasound imaging systems" and that it "will add volume imaging to conventional diagnostic ultrasound images."
No
The device description explicitly states it is a "volume imaging transducer," which is a physical hardware component used in ultrasound systems. It is a modification of an existing transducer.
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 an in vivo diagnostic procedure, meaning it's performed on a living organism.
- Device Description: The device is a "volume imaging transducer" for use with diagnostic ultrasound imaging systems. Ultrasound is a non-invasive imaging technique applied externally to the body.
- Lack of IVD Characteristics: IVD devices are designed to examine specimens (like blood, urine, tissue) taken from the human body to provide information about a physiological state, health, or disease. This device does not interact with such specimens.
Therefore, this device falls under the category of a medical imaging device used for in vivo diagnosis, not an in vitro diagnostic device.

Device Description
The PVF-375DT volume imaging transducer is a modification of the PVF-375MT convex transducer that was cleared for the SSA-340A, SSA-270A and SSH-140A diagnostic ultrasound imaging systems. It will add volume imaging to conventional diagnostic ultrasound images. Volume imaging is due to the physical characteristics of the device and is intended to assist with patient education during an examination.

§ 892.1570 Diagnostic ultrasonic transducer.
(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)
Classification. Class II.

Modification of the PVF-375MT Reason for Submission:
Substantial Equivalence Summary:
The PVF-375DT volume imaging transducer is a modification of the PVF-375MT convex transducer that was cleared for the SSA-340A, SSA-270A and SSH-140A diagnostic ultrasound imaging systems. It will add volume imaging to conventional diagnostic ultrasound images. Volume imaging is due to the physical characteristics of the device and is intended to assist with patient education during an examination.
The PVF-375DT follows previously cleared software verification and validation procedures and employs the same general technology as that most lately cleared for the PVF-375MT. It does not affect cleared patient contact materials or acoustic output intensities. Based on a review of TAMS Complaint and MDR files for similar transducers, any potential failure of this transducer is not expected to result in an injury to the patient.
TAMS believes that the PVF-375DT is substantially equivalent to the PVF-375MT because it does not change the cleared safety and effectiveness attributes or the indications for use of the PVF-375MT.

Re: K972771 Phased Array Tranducer - PVF-375DT Dated: November 7, 1997 Received: November 13, 1997 Regulatory class: II 21 CFR 892.1570/Procode: 90 ITX
Dear Mr. Biggins:
We have reviewed your section 510(k) 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 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. You may, therefore, market the device, subject to the general controls provisions Act (Act). The general controls provisions of the Act include requirements for registration, listing of devices, good manufacturing practices, labeling, and prohibitions against misbranding and adulteration.
This determination of substantial equivalence applies to the following transducers intended for use with the SSA-340A, SSA-270 and SSA-140A Ultrasound Systems, as described in your premarket notification:
Transducer Model Number
PVF-375DT
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 895. A substantially equivalent determination assumes compliance with the Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General (GMP) regulation (21 CFR Part 820) and that, through periodic QS inspections, the FDA will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, the Food and Drug Administration (FDA) may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification does not affect any obligation you may have under sections 531 and 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
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.
