Dear Dave Yungvirt:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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

{1}------------------------------------------------

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 of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

# Section 5 - 510(k) Summary

# 5.1 DEVICE DESCRIPTION

eKuore Pro Series is formed by eKuore Pro Series device and eKuore Pro App.

The eKuore Pro Series device introduce three different models:

- . eKuore Pro, the basic version of the stethoscope.
- eKuore Pro Amplified, that has a higher sound amplification designed for . people with hearing problems

The main purpose of eKuore Pro Series device is the detection and amplification of heart, lung, arteries, veins and internal sounds using selective frequency organ ranges. eKuore Pro and eKuore Pro Amplified creates a WLAN access point, to which the client is able to connect via Wi-Fi with smartphones and tablets, to send the data acquired during auscultation to the eKuore Pro App.

The design of eKuore Pro Series lets the user change the chestpiece attached between different sizes depend on the patient to be auscultated.

The main purpose of the eKuore Pro Series App is to get the acoustic signals from the eKuore Pro Series WLAN access point. Once the device is turn on, a new Wi-Fi signal could be detected by the smartphone/tablet, the signal name contains the last 6 digits of the serial number of the device for its identification.

After the connection, the eKuore Pro App displays the acoustic signal as a phonogram in real time, in the monitor screen there is a record button. When it is pressed the recording start, there is defined a record maximum duration of 30 seconds, it could be changed on the App configuration to 60. 90 or 120 seconds. To stop the record the recording button must be pressed again. Recordings are stored in *.wav file format in the internal memory of the connected smartphone/tablet, each recording is stored named with the date and time of the moment of the record.

eKuore Pro App has a management screen where it is possible to play, remove and edit a recording. Only the length and the name of the record file could be edited. Also, the eKuore Pro App lets the user share the records.

Furthermore, eKuore Pro App has a tutorial to help the user and one "About App" screen where access to support is available.
