## Indications for Use

The AUSCO ES-3100 Electronic Stethoscope is intended for medical diagnostic purposes. It may be used for the amplification of sounds associated with the heart, lungs, arteries, veins, and other internal organs. It can be used on any person undergoing a physical assessment.

## Device Story

AUSCO ES-3100 is an electronic stethoscope for clinical auscultation. Device captures internal body sounds (heart, lungs, arteries, veins) via a sensor; processes signals through active high and low pass filtering circuits to provide two frequency modes: Bell (20-200Hz) and Diaphragm (20-1000Hz). Amplified audio is delivered to the clinician via an active speaker and passive sound tubes. Features include volume control, frequency mode selection, and automatic power-off. Operated by healthcare professionals during physical assessments to aid in diagnosis by enhancing sound clarity and reducing frictional noise. Powered by two AAA alkaline batteries.

## Clinical Evidence

Bench testing only. Biocompatibility testing performed per ISO 10993-1 for limited skin contact. Electrical safety and EMC testing performed per IEC/ISO/EN 60601-01 and 60601-01-02.

## Technological Characteristics

Electronic stethoscope with active high/low pass filtering. Frequency modes: Bell (20-200Hz), Diaphragm (20-1000Hz). Power: 2x AAA alkaline batteries. Biocompatibility: ISO 10993-1 compliant. Safety/EMC: IEC/ISO/EN 60601-01 and 60601-01-02. Embedded firmware controls volume, frequency selection, and power management.

## Regulatory Identification

Manual stethoscope: A mechanical device used to project the sounds associated with the heart, arteries, and veins and other internal organs. Electronic stethoscope: An electrically amplified device used to project the sounds associated with the heart, arteries, and veins and other internal organs.

## Special Controls

*Classification.* Class II (special controls). The device, when it is a lung sound monitor, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 870.9.

## 4. Description of Device:

The AUSCO ES-3100 Electronic Stethoscope is a healthcare device that clectronically filters and amplifies sounds of the heart, lungs, arteries, veins and other internal organs, and transfers them to the user's ears through an active speaker and passive sound tubes. The AUSCO ES-3100 provides two filter frequency modes for auscultation: Bell (20 to 200Hz) and Diaphragm (20 to 1000Hz).

{1}------------------------------------------------

K070550/51
P2/2

The AUSCO ES-3100 incorporates electronics and embedded software, which controls all of the various features such as volume control, frequency mode selection, and automatic powering off of the stethoscope. Active high and low pass filtering circuits are employed to produce the bell and diaphragm frequency response modes that are used to listen to the heart, lungs and other body sounds, while reducing frictional noises.

The AUSCO ES-3100 does not employ any off-the-shelf-software.

The AUSCO ES-3100 uses two (2) AAA alkaline batteries.

## Indications for Use: ನ.

The AUSCO ES-3100 Electronic Stethoscope is intended for medical diagnostic purposes. It may be used for the amplification of sounds associated with the heart, lungs, arteries, veins, and other internal organs. It can be used on any person undergoing a physical assessment.

# Comparative Data for Determining Substantial Equivalence to Predicate Device: 6.

The similarities and differences of the AUSCO ES-3100 (new device) were compared to predicate devices (Littmann® models 2000 and 3000 and ADC 656). The proposed device under this new pre-market notification is similar in characteristics, materials, features, has similar performance features, intended use and indications for use as the Littmann " Model 2000 cleared under K961848 (September 26, 1997 clearance date), the Littmann® Model 3000 cleared under K041934 (October 15, 2004 clearance date) and American Diagnostic Corporation's ADC 656 electronic stethoscope cleared under K012304 (November 1, 2001 clearance date).

# Non-Clinical Performance Summary: 7.

Components of the AUSCO ES-3100 electronic stethoscope have been reviewed for biocompatibility and conform to ISO10993-Part 1 Biological Evaluation of Medical Devices for limited (≤ 24 hour) skin contact for direct patient exposure.

The AUSCO ES-3100 electronic stethoscope was tested and conforms to applicable safety and EMC requirements found in the IEC/ISO/EN 60601-01 and IEC/ISO/EN 60601-01-02 international standards.

#### 8. Conclusions:

The AUSCO ES-3100 electronic stethoscope is similar if not identical in materials, technological characteristics, and has the same intended use as the predicate devices. Any differences in technological characteristics between the AUSCO ES-3100 and the predicate devices do not raise any new questions of safety or effectiveness.

We conclude that the AUSCO ES-3100 electronic stethoscope is substantially equivalent to the predicate devices.

You may, therefore, market the device, subject to the general controls provisions of the Act. 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.

If vour device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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.
