Device Description
The Stethee Pro 1 is an electronic stethoscope intended for medical screening or diagnostic purposes only. Stethee Pro 1 may be used for detection and amplification of sounds from the heart, lungs, arteries, veins, and other internal organs with or without the use of selective filters. It can be used on any person undergoing a physical assessment. The Stethee Pro 1 consists of hardware and embedded software which controls all of the various features found in the device, such as sound capture, digital signal processing, volume control, haptic feedback for user, LED display ring, and wireless data transfer (via Bluetooth®). No patient data is stored on the Stethee Pro 1 device itself. After amplification and filtering of the sounds detected, Stethee Pro 1 transfers the sounds to the User's ears via any Bluetooth® connected headphones, or by wired headphones connected to Stethee Pro 1 using an AUX adaptor at the device's USB port. The Stethee Pro 1 also includes features that permit it to stream sounds to a peripheral smart device (e.g., mobile phone) as an audio buffer to a smart device (iOS or Android) via a Bluetooth® connection. The audio buffer is handled on the smart device by a separate standalone software application called the Stethee Pro Software System. Stethee Pro Software System (SPS) is a series of software applications (Stethee Pro Mobile Applications and the Stethee Pro Central Web Application) that work with the Stethee Pro 1 electronic stethoscope. Stethee Pro Software System is supported by M3DICINE's proprietary software platform M3DICINE Cloud Services (MCS) which provides various services including database, security, and core business logic services so that services for data sharing and multiple sign-ins from multiple devices can be implemented.
More Information

Yes
The summary explicitly mentions "machine learning analysis algorithms" and "clinical validation of the performance accuracy of the device's machine learning analysis algorithms".

No
The device is described as an electronic stethoscope for screening and medical diagnostic purposes, focusing on detection and amplification of sounds, not on treating or restoring health.

Yes.
The "Intended Use / Indications for Use" section explicitly states that the device is "intended for screening and medical diagnostic purposes only."

No

The device description explicitly states that the Stethee Pro 1 "consists of hardware and embedded software" and describes hardware components like sound capture, digital signal processing, volume control, haptic feedback, LED display, and wireless data transfer. While it interacts with software systems, the core medical device itself includes hardware.

Based on the provided text, the Stethee™ Pro 1 is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
  • Stethee Pro 1 Function: The Stethee Pro 1 is an electronic stethoscope that detects and amplifies sounds from within the body (heart, lungs, etc.). It does not analyze specimens taken from the body.
  • Intended Use: The intended use clearly states it's for "screening and medical diagnostic purposes only" by detecting and amplifying internal body sounds.

While the device uses software for analysis and management of the collected sounds, the core function of the device itself is not based on analyzing biological specimens.

No
The provided text does not explicitly state that the FDA has reviewed and approved or cleared a PCCP for this specific device. The section "Control Plan Authorized (PCCP) and relevant text" is marked "Not Found," indicating the absence of such language.
