The summary describes "analysis procedure" and "computer-assisted auscultatory device" but does not explicitly mention AI, ML, or related terms, nor does it provide details about training or test sets typically associated with such technologies.
No
The device aids in the evaluation of heart sounds and identifies suspected murmurs, but it is explicitly stated "It is not intended as a sole means of diagnosis" and results are "only significant when used in conjunction with physician over-read as well as consideration of all other relevant patient data." This indicates it's a diagnostic aid, not a device that provides therapy.
Yes
The device is intended to provide support to the physician in the evaluation of heart sounds and identify specific heart sounds that may be present, which aligns with the purpose of a diagnostic device. Although it states it is "not intended as a sole means of diagnosis," it does contribute to the diagnostic process.
No
The device description explicitly states that the ZAC system consists of an electronic stethoscope, a laptop computer, software, and a printer, indicating it includes hardware components beyond just software.
Based on the provided information, the Zargis Acoustic Cardioscan (ZAC) is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD devices are used to examine specimens derived from the human body. The ZAC acquires and analyzes acoustic signals directly from the patient's chest (heart sounds). It does not process biological samples like blood, urine, tissue, etc.
- The intended use and device description clearly state it's an electronic auscultatory device for evaluating heart sounds. This is a non-invasive method of examining the body directly.
Therefore, the ZAC falls under the category of a medical device, but not specifically an In Vitro Diagnostic device.

PERFORMANCE STANDARDS:
The device complies or will comply with the relevant international Safety Standards. It has been manufactured in compliance with the Quality System Regulation.
SYSTEM DESCRIPTION:
The ZAC is a computer-assisted auscultatory device, intended to provide support to the target users in the evaluation of heart sounds and murmurs. The product will acquire and record the acoustic signal of the heart, over appropriate regions of the chest, and then analyze these signals. The analysis procedure will evaluate sounds of the heart and aid healthcare providers in identifying murmurs. Results are presented to the user in near real-time.
As a complete system, the ZAC consists of an electronic stethoscope, a laptop computer. software, and a printer.
The ZAC system was cleared by FDA on 26 May 2004. The proposed revisions, included as part of this submission, do not affect the current method of operation, data acquisition, processing, or existing data analysis in any way.
1
Zargis wishes to submit, for FDA review, a revision to the previously cleared ZAC system. The proposed changes to the system:
-
- Add, to the existing user interface, a graphical display of timing and energy of any suspected murmurs that may have been identified.
- Revise the existing Heart Sound Recording Display to remove the "mm" label from 2. shaded areas designating the location of suspected murmurs
-
- The wording of the summary reports returned when suspected murmurs identified have been changed to include a designation of the heartbeat interval in which the suspected murmur occurs
-
- Minor software revisions to correct or adjust operational anomalies identified since the previous submission
- a. Adjusted sequence of software routine calls to shorten analysis time
- b. Store software revision level as part of patient record
- Have software license expire annually c.
- d. For increased security, disable Windows shortcut keys
- For increased security, disable Ethernet card and jump drive e.
EQUIVALENCE INFORMATION:
Zargis wishes to receive FDA clearance to market this revised product based on its substantial equivalence to the original device cleared by FDA. There are no changes in intended use of the product, nor any changes in technology. The previously cleared system included a graphical display of the heart sound and graphically highlighted the suspected murmur. The new display will identify in which of 4 time periods (subdivisions of the cardiac waveform) the suspected murmur occurs and provides a metric that establishes the onset and duration timing of the suspected murmur. The graphical display also presents, in histogram format, the sound energy during each time period. The revised graphical representation allows an increased level of quantification of the display.
SAFETY INFORMATION:
The results of the hazard analysis, combined with the appropriate preventive measures taken indicate the change to the ZAC, as the ZAC itself, is of minor level of concern, per the August 29, 1991 issue of the "Reviewers Guidance for Computer Controlled Medical Devices Undergoing 510(k) Review".
The ZAC device continues to have no patient contacting materials and is utilized only by trained professionals. As it was for the original ZAC, the output of the improved device is evaluated by trained professionals allowing sufficient review to afford identification and intervention in the event of a malfunction. Device output and analysis is used to indicate the appropriateness of a referral. The device impacts the quality or status of the original acquired data only in the validated manner described.
Zargis feels that sufficient information and data are contained in this submission to enable CDRH to reach a determination of substantial equivalence within a reasonable time period. In the event that additional information is required, please contact Zargis Medical Corp.

Dear Mr. Brooks:
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.
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 letter will allow you to begin marketing your device as described in your Section 510(k) 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 the 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) 594-4648. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97).
