Intended Use

The AMPLIFE Wrist Watch Blood Pressure Monitor, Model M600 is a device intended to measure the systolic and diastolic blood pressure and pulse rate of an individual by using a non-invasive technique in which an inflatable cuff is wrapped around the Wrist.

Device Story

AMPLIFE Model M600 is a wrist-worn, auto-inflation oscillometric blood pressure monitor. Device uses an electronic semiconductor sensor to detect pressure alterations in an inflatable cuff; sensor converts these to electrical signals. Software algorithm analyzes signals to calculate systolic/diastolic blood pressure and pulse rate. Intended for over-the-counter use by individuals to monitor blood pressure at home. Deflation rate is controlled by a factory-set bleed valve. Output is displayed to the user for personal health tracking.

Clinical Evidence

Clinical testing performed according to ANSI/AAMI SP-10 standard. No specific numerical results (sensitivity/specificity) provided in the summary; device demonstrated safety and effectiveness equivalent to the predicate.

Technological Characteristics

Oscillometric blood pressure monitor; electronic semiconductor sensor; auto-inflation cuff; factory-set bleed valve for deflation; wrist-worn form factor; software-based signal processing.

Indications for Use

Indicated for individuals requiring non-invasive measurement of systolic and diastolic blood pressure and pulse rate via a wrist-worn inflatable cuff.

Regulatory Classification

Identification

A noninvasive blood pressure measurement system is a device that provides a signal from which systolic, diastolic, mean, or any combination of the three pressures can be derived through the use of tranducers placed on the surface of the body.

## EXHIBIT # 1

## 510(K) SUMMARY

This summary of 510(k) safety and effectiveness information is being submitted in accordance with the requirements of SMDA 1990 and 21 CFR §807.92.

The assigned 5l0(k) number is:

#### Submitter's Identification: 1.

AMPLIFE Corporation 10F, No. 69, Sec. 3, Hue Jung Rd Taichung, Taiwan, R.O.C

Date Summary Prepared: January 25, 2005

#### 2. Name of the Device:

AMPLIFE Wrist Watch Blood Pressure Monitor, Model M600

## Common Name or Classification Name:

Wrist Watch Blood Pressure Monitor / Auto-Inflation Oscillometric Digital Blood Pressure Monitor

#### 3. Predicate Device Information:

The AMPLIFE Wrist Watch Automatic Blood Pressure Monitor, Model M600 is substantially equivalent to the Microlife Automatic Wrist Watch Blood Pressure Monitor, Model BP3AX1, K# 040002.

#### 4. Device Description:

The AMPLIFE Wrist Watch Automatic Blood Pressure Monitor, Model M600 is designed to measure the systolic and diastolic blood pressure and pulse rate of an individual by using a non-invasive technique in which an inflatable cuff is wrapped around the Wrist. Our method to define systolic and diastolic pressure is similar to the auscultatory method but uses an electronic semiconductor sensor rather than a stethoscope and mercury manometer. The sensor converts tiny alterations in cuff pressure to electrical signals, by analyzing those signals to

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

define the systolic and diastolic blood pressure and calculating pulse rate, which is a well known technique in the market called the "oscillometric method".

#### Intended Use: 5.

The AMPLIFE Wrist Watch Blood Pressure Monitor, Model M600 is a device intended to measure the systolic and diastolic blood pressure and pulse rate of intendou to ividual by using a non-invasive technique in which an inflatable cuff is wrapped around the Wrist.

#### Comparison to Predicate Devices: 6.

The AMPLIFE Wrist Watch Automatic Blood Pressure Monitor, Model M600 and the predicate device are identical in functionality and performance with the difference being the external shape of the devices, and PCB layout of the devices, performance specifications, ergonomics of the user interface, dimensional specifications, display mode and memory function, which do not make any effects on the performance of the device. The blood pressure measurements algorithm and its fundamental scientific technology are identical to the predicate device.

Both devices use the well-known oscillometric method within the software algorithm to determine the systolic and diastolic blood pressure and pulse rate. A wrist watch cuff is inflated automatically; deflate rate is controlled but a factory set bleed valve and the deflation pressures are transferred via tubing to a sensor in both units.

### Discussion of Non-Clinical Tests Performed for Determination of 7. Substantial Equivalence are as follows:

Testing information demonstrating safety and effectiveness of the AMPLIFE Automatic Wrist Watch Blood Pressure Monitor, Model M600 in the intended environment of use is supported by testing that was conducted in accordance with the FDA November 1993 Draft "Reviewer Guidance for Premarket Notification Submissions", DCRND, which outlines Electrical, Mechanical and Environmental Performance Requirements.

The following testing was conducted:

- General Functions Test a.
- Reliability Test Operation Conditions b.
- Reliability Test Drop Testing C.
- Reliability Test Storage ದ.

{2}------------------------------------------------

- Reliability Test Vibrating Testing e.
- سن EMC Test
- IEC 60601-1 Safety Test g.

None of the testing demonstrated any design characteristics that violated the None of the Reviewer Guidance or resulted in any safety hazards. It was requirements of the Reviewer OE Automatic Blood Pressure Monitor, Model our conclusion that the Allant requirements of the aforementioned tests.
