Intended Use
The Strados Remote Electronic Stethoscope Platform (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 or outpatient setting including transition from healthcare setting to outpatient care without interruption. The device stores the data for later playback, review, and analysis by a clinician and comparison with earlier data from the same patient.
Device Description
The Strados Remote Electronic Stethoscope Platform (RESP) is a non-invasive battery-operated device, including a wearable component, intended to longitudinally acquire, record, and store lung sounds from adult patients. The device stores the data for later playback, review, and analysis by a clinician and comparison with earlier data from the same patient. 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 airway sounds, including but not limited to cough, wheeze, rhonchi, rales, crackles, coarse (bronchial) breath sounds, quiet breathing, and chest wall movement onto internal memory. 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 and outpatient setting including the home.
More Information

No
The summary explicitly states "Mentions AI, DNN, or ML: Not Found" and describes the device as storing data for "later playback, review, and analysis by a clinician". There is no mention of automated analysis or algorithms that would suggest AI/ML.

No
The device is described as a non-invasive battery-operated device intended to acquire, record, and store lung sounds for later playback, review, and analysis by a clinician. It aids in diagnosis and monitoring, not treatment.

Yes

The device is intended to acquire, record, and store lung sounds for "later playback, review, and analysis by a clinician," which are activities performed to diagnose conditions.

No

The device description explicitly states it includes hardware components: the Strados Wearable Device (SWD), Strados Charging Station (SCS), external power supply, and Strados Patient Adhesive (SPA). While it uses a mobile application for control and playback, it is not solely software.

Based on the provided information, the Strados Remote Electronic Stethoscope Platform (RESP) is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: IVD devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information about a person's health. This examination is performed in vitro (outside the body).
  • Strados RESP Function: The Strados RESP is a non-invasive device that acquires, records, and stores lung sounds directly from the patient's chest wall. It does not analyze specimens taken from the body. Its purpose is to provide clinicians with acoustic data (lung sounds) for review and analysis.

The device's function aligns with that of a medical device used for physiological monitoring and data acquisition, not an IVD.

Dear Prithul Bom:

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.
