Intended Use
The CardioSleeve System consisting of the CardioSleeve Front-End stethoscope with integrated ECG device. mobile heart sound and ECG recording application and the remote diagnostic heart murmur software is a decision support device intended to be used on a single patient to assist the qualified clinician in analyzing cardiac sounds and electrical signals for the identification and classification including of suspected murmurs. It is used to distinguish between normal/physiological and pathological heart murmurs by recording the acoustic signal of the heart and the ECG signal simultaneously and analyzing these signals. The acoustic heart signal is analyzed to identify specific heart sounds that may be present. Identified sounds include S1, S2, and suspected murmurs. CardioSleeve indicates whether or not a recorded heart sound contains a suspected heart murmur. The device must be used in a clinical setting by trained personnel with the prescribed accessories and all relevant patient information must be taken into consideration before a diagnosis is made. The interpretations of heart sounds offered by the CardioSleeve device are only significant when used in conjunction with physician over-read as well as consideration of all other relevant patient data. CardioSleeve is not intended to be a diagnostic device. It does not supersede the judgment of the clinician. The device is intended to aid the physician in the evaluation of heart sounds.

Unknown
The summary mentions a "Diagnostic Heart Murmur Algorithm" and "analyzing these signals" to distinguish between normal and pathological murmurs. While this suggests algorithmic processing, it doesn't explicitly state whether AI or ML techniques are used in this algorithm. The lack of mention of AI, DNN, or ML in the dedicated section further contributes to the uncertainty.

No
The device is described as a "decision support device" intended to assist clinicians in analyzing cardiac sounds and electrical signals for the identification and classification of suspected murmurs. It explicitly states it is "not intended to be a diagnostic device" and "does not supersede the judgment of the clinician." It aids in evaluation but does not provide therapy or treatment.

No
Explanation: The "Intended Use / Indications for Use" section explicitly states, "CardioSleeve is not intended to be a diagnostic device."

No

The device description explicitly states that the complete system comprises a "stethoscope front-end recorder device with integrated ECG to acquire the acoustic and electrical heart signals," which is a hardware component.

Based on the provided text, the CardioSleeve System is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • Intended Use: The intended use explicitly states that the device is a "decision support device" and is "not intended to be a diagnostic device." It is designed to assist clinicians in analyzing cardiac sounds and electrical signals, but the final diagnosis is made by the clinician.
  • Nature of the Signals: The device analyzes acoustic signals (heart sounds) and electrical signals (ECG). IVD devices typically analyze samples taken from the body, such as blood, urine, or tissue.
  • Clinical Setting: The device is used directly on the patient in a clinical setting, not in a laboratory setting for testing samples.

Therefore, the CardioSleeve System falls under the category of a medical device that provides information to aid in diagnosis, but it is not an IVD.
