Intended Use
The HeartBuds Stethoscope is an electronic stethoscope that enables transmission of auscultation sound data, whereby a clinician at one location via the HeartBuds mobile application can listen to the auscultation sounds of a patient at a different location. The HeartBuds Stethoscope is intended to be used by professional users in a clinical environment or by non medical professional adult users in a non clinical environment. The device is for medical diagnostics purposes only. The device is not intended for self-diagnosis.
Device Description
HeartBuds is an electronic stethoscope intended to auscultate heart and lung sounds. HeartBuds Stethoscope can be used on any patient undergoing a physical assessment. This stethoscope consists of a hand-held device with integral plastic sound diaphragm, that must be used together with a smartphone equipped with the HeartBuds application software. HeartBuds Stethoscope allows users to digitally record heart and lung internal auscultation and transmit the sound data to a medical professional in another location. The HeartBuds system includes two (2) main components: The HeartBuds Electronic Stethoscope and the HeartBuds mobile app. The HeartBuds Electronic Stethoscope connects to mobile devices (Apple and Android) by means of an audio cable. The HeartBuds app with the integrated HeartBuds software provides users a platform to listen, display, and record sounds simultaneously using an external microphone. The users can share their recordings with their healthcare provider within the HeartBuds app for remote examination.
More Information

Not Found

No
The document describes a device for recording and transmitting auscultation sounds, but there is no mention of AI or ML being used for analysis, interpretation, or any other function. The "Mentions AI, DNN, or ML" section explicitly states "Not Found".

No
The device is described as being for "medical diagnostics purposes only" and is intended to "auscultate heart and lung sounds" and "record heart and lung internal auscultation." It facilitates remote examination by allowing sound data transmission, which is a diagnostic function, not a therapeutic one.

Yes

The "Intended Use / Indications for Use" section explicitly states, "The device is for medical diagnostics purposes only."

No

The device description explicitly states that the system includes a "hand-held device with integral plastic sound diaphragm" and an "Electronic Stethoscope" component, which are hardware components.

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

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices intended for use in vitro for the examination of specimens, including blood, tissue, and urine, derived from the human body, solely or principally for the purpose of providing information concerning a physiological or pathological state, or concerning a congenital abnormality, or to determine the safety and compatibility with potential recipients, or to monitor therapeutic measures.
  • HeartBuds Function: The HeartBuds Stethoscope is used for auscultation, which is the act of listening to internal sounds of the body, primarily the heart and lungs, using a stethoscope. This is a non-invasive method of physical examination.
  • Specimen Analysis: The HeartBuds Stethoscope does not analyze any specimens derived from the human body (like blood, tissue, or urine). It captures and transmits sound data from within the body.

Therefore, the HeartBuds Stethoscope falls under the category of a medical device used for physical examination and remote auscultation, but it does not meet the definition of an In Vitro Diagnostic device.

Description | The HeartBuds Stethoscope
when connected to the
HeartBuds App, captures
sounds by the HeartBuds
Stethoscope which can be
recorded by the App and
stored to the cloud for future
use. The HeartBuds mobile
application on the smartphone
records those sounds as an
audio recording to be stored
and if desired by the user to be
shared with a healthcare
provider. The HeartBuds App
requires a user to register and
create a secure login in order
to provide a means to associate
the recordings to each
individual user and to be
stored in the cloud (Google
application Firebase). The
HeartBuds App provides the
capability to start and stop
recording at the user's
discretion. The HeartBuds
App also provides the
capability for the user to
sample the sounds received
from the HeartBuds
Stethoscope before starting a
recording. This provides a
means for the user to either
change the position of the
Stethoscope to ensure the
recording includes sounds of
the heart or lung. The user

Discussion of Similarities and Differences

Summary of Similar Technological Characteristics.

The HeartBuds electronic stethoscope and the predicate are both electronic stethoscopes intended for projecting the sounds associated with vibrations or sounds of the human body. Therefore, they have the same intended use and core technology,

Both the Tyto Stethoscope and the HeartBuds Stethoscope are intended to transmit the recorded auscultation sounds to a remote location where a clinician can listen to them. In addition, both these devices are indicated for use by adult lay users (i.e., adults who are not health care professionals).

As shown in the table above, the HeartBuds Stethoscope shares with its predicate device similar structural design and similar principles and mode of operation as follows:

  • The indications for use is similar with the subject device having fewer capabilities for data 1. collection and processing.
    1. The core technology is the same, although the predicate utilizes wireless communications
  • The classification code is the same 3.
    1. Both devices are indicated for OTC devices that can be used in the home as well as in a clinical environment.
    1. Both devices are compliant with relevant safety standards (see performance data in this submission for ISO 10993, IEC 60601-1, IEC 60601-1-2 and ISO 62366)
  • Both devices use downloadable Apps for Android and iOS 6.
  • Both the HeartBuds Stethoscope and the Tyto Stethoscope record auscultation 7.
    1. Both the HeartBuds Stethoscope and the Tyto Stethoscope store the recording on smart phone storage
    1. Both the HeartBuds Stethoscope and the Tyto Stethoscope allow the user to share the recording
    1. Both the HeartBuds Stethoscope and the Tyto Stethoscope provide a transfer of the recording to on-line applications (via email, cloud storage)

Summary of Different Technological Characteristics.

As shown in the table above, the HeartBuds Stethoscope has some differences from the predicate device. Where these differences exist, performance data is provided in this submission to demonstrate that the differences do not raise any new issues of safety or effectiveness.

  • The HeartBuds device has more limited capabilities than the Tyto device as listed in the table 1. above. Because there are fewer capabilities there are fewer risks associated with the correct delivery of information to the health care professional who will review the device output.
  • Information on the specific materials used for the predicate are not available but are ISO 10993 2. compliant. Therefore, although the materials are not the same, both are substantially equivalent in that they are both compliant with ISO 10993.
