Device Description
The RESP is a non-invasive battery-operated device, including a wearable component, intended to longitudinally acquire, record, and store lung sounds from adult patients in a healthcare setting. The device stores the data for later playback, review, and analysis by a clinician on a mobile app. The Strados Remote Electronic Stethoscope Platform (RESP) is comprised of the Strados Wearable Device (SWD), Strados Charging Station (SCS) and external power supply, and Strados Patient Adhesive (SPA) used to adhere the SWD to the patient. The SWD is controlled by a mobile device running the Strados Mobile Application (SMA) via Bluetooth connection. The Strados Wearable Device (SWD) sits on the chest wall and passively records the patient's lung sounds. The Strados Mobile App (SMA) on a smartphone allows playback of lung sounds from the wearable device in order for clinicians to listen to the patient's lung sounds. The device is used in a healthcare setting.
More Information

No
The description focuses on data acquisition, recording, storage, and playback for clinician review. There is no mention of automated analysis, pattern recognition, or any technology that would typically involve AI/ML for interpretation or diagnosis.

No.
The device is intended to acquire, record, and store lung sounds for review and analysis by a clinician, which is a diagnostic function, not a therapeutic one.

No
The device is limited to acquiring, recording, and storing lung sounds for later playback, review, and analysis by a clinician. It does not perform any diagnostic function itself.

No

The device description explicitly states it includes hardware components: a wearable device, charging station, external power supply, and patient adhesive. It is not solely software.

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

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. These tests are performed outside of the body (in vitro).
  • Device Function: The RESP device acquires, records, and stores lung sounds directly from the patient's chest wall. This is a non-invasive process that involves listening to sounds produced within the body. It does not involve analyzing samples taken from the body.
  • Intended Use: The intended use is to acquire, record, and store lung sounds for later playback, review, and analysis by a clinician. This is a form of physical examination and data collection, not an in vitro diagnostic test.

The device functions more like an electronic stethoscope with recording capabilities, which is a diagnostic tool used for physical examination, not an IVD. The predicate and reference devices listed (electronic stethoscopes) further support this classification.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Clinical performance testing was performed to validate the quality of the subject device's recorded lung sounds.

Non-Clinical performance testing conducted includes:

  • Frequency response equivalence testing from 20 to 2000Hz against a reference 510(k) cleared stethoscopes
  • Functional Testing
  • Validation of device cleaning instructions for likely use
  • Ship Testing

The biocompatibility evaluation of the subject device was based on ISO 10993-1:2009 Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process. This includes Cytotoxicity, Sensitization and Intracutaneous Reactivity/Irritation testing was passed.

Dear Grace Powers:

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 statutes and regulations administered by other Federal agencies. You must comply with all the Act's

Clinical Performance Data

Clinical performance testing was performed to validate the quality of the subject device's recorded lung sounds.

Non-Clinical Performance Data

The subject device was subject to non-clinical performance testing. There are no device-specific guidance documents, special controls document, and/or requirements in a device-specific regulation that is applicable to the subject device. A list of the standards, guidance and additional testing for all the devices is listed below:

  • . IEC 60601-1:2005, COR1:2006, COR2:2007, AMD1:2012- Medical electrical equipment - Part 1: General requirements for basic safety and essential performance
  • . AAMI/IEC 60601-1:2005 + AMD 1:2012- Medical electrical equipment - Part 1: General requirements for basic safety and essential performance
  • IEC 62366-1:2015- Medical devices — Part 1: Application of usability engineering to medical devices
  • IEC 62304:2006-Medical device software - Software life cycle processes
  • . UL 62368-1:2012- Audio/video, information and communication technology equipment - Part 1: Safety requirements

IEC 60601-1-6:2010- Medical electrical equipment - Part 1-6: General requirements for basic safety and essential performance - Collateral standard: Usability

  • Additional Non-Clinical performance testing conducted includes:
    • Frequency response equivalence testing from 20 to 2000Hz against a reference 510(k) O cleared stethoscopes
    • O Functional Testing
    • o Validation of device cleaning instructions for likely use
    • Ship Testing O

The Strados Wearable Device is considered as surface devices in contact with intact skin. The biocompatibility evaluation of the subject device was based on ISO 10993-1:2009 Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process. This includes Cytotoxicity, Sensitization and Intracutaneous Reactivity/Irritation testing was passed.

Conclusion

The Strados Remote Electronic Stethoscope Platform (RESP) is substantially equivalent to the legally marketed predicate device as demonstrated by the similar indication for use, similar technologies and performance data, and does not raise different questions of safety and effectiveness.
