Intended Use

Microlife Wrist Watch Blood Pressure Monitor, Model BP3AX1-4U is a device intended to measure the systolic and diastolic blood pressure and pulse rate of an adult individual by using a technique in which an inflatable cuff is wrapped around the wrist. The device can be used in connection with your personal computer (PC) running the Microlife Blood Pressure Analyzer (BPA) software. The memory data can be transferred to the PC by connecting the monitor via cable with the PC.

Device Story

The Microlife Wrist Watch Blood Pressure Monitor (Model BP3AX1-4U) is an automated non-invasive blood pressure monitor. It uses an inflatable wrist cuff and an electronic semiconductor pressure sensor to detect pressure variations, which are converted into electrical signals. The device employs the oscillometric method to calculate systolic and diastolic blood pressure and pulse rate. It features a MAM (Microlife Average Mode) function. The device is intended for use by adults. Users can transfer stored measurement data to a personal computer (PC) via a cable connection for analysis using the Microlife Blood Pressure Analyzer (BPA) software. This allows for long-term tracking and management of blood pressure data, aiding in clinical decision-making by providing a record of measurements.

Clinical Evidence

No new clinical testing was performed for the modified device. The manufacturer relied on clinical data from the predicate device (K040002), which was tested against the ANSI/AAMI SP10-2002 standard for electronic sphygmomanometers. The manufacturer concluded that the modifications (addition of PC-link functionality) did not affect clinical performance results.

Technological Characteristics

Non-invasive oscillometric blood pressure monitor; semiconductor pressure sensor; automatic cuff inflation; factory-set bleed valve for deflation; PC connectivity via cable; MAM (Microlife Average Mode) function; software-based algorithm for signal processing.

Indications for Use

Indicated for adult individuals to measure systolic and diastolic blood pressure and pulse rate via an inflatable wrist 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 510(k) number is:

#### 1. Submitter's Identification:

Microlife Intellectual Property GmbH, Switzerland

Max Schmidheiny-Strasse 201 9435 Heerbrugg / Switzerland

Date Summary Prepared: May 18, 2006

Contact: Mr. Gerhard Frick

### 2. Name of the Device:

Microlife Wrist Watch Blood Pressure Monitor, Model BP3AX1-4U

#### 3. Information for the 510(k) Cleared Device (Predicate Device):

Microlife Wrist Watch Blood Pressure Monitor, Model BP3AX1, K#040002.

#### 4. Device Description:

The Microlife Wrist Watch Blood Pressure Monitor, Model BP3AX1-4U is designed to measure the systolic and diastolic blood pressure and pulse rate of an individual by using a technique in which an inflatable cuff is wrapped around the wrist. Our method to define systolic and diastolic pressures is similar to the auscultatory method but uses an electronic semiconductor pressure sensor rather than stethoscope and mercury manometer. The sensor converts tiny alteration in cuff pressure to electrical signals; by analyzing those signals to define the systolic, diastolic and calculating pulse rate is a well known technique in the market called the "oscillometric method". The device can be used in connection with your personal computer (PC) running the Microlife Blood Pressure Analyzer (BPA) software. The memory data can be transferred to the PC by connecting the monitor via cable with the PC.

### ട. Intended Use:

Microlife Wrist Watch Blood Pressure Monitor, Model BP3AX1-4U is a device intended to measure the systolic and diastolic blood pressure and pulse rate of an adult individual by using a technique in which an inflatable cuff is wrapped around the wrist.

The device can be used in connection with your personal computer (PC) running the Microlife Blood Pressure Analyzer (BPA) software. The memory data can be transferred to the PC by connecting the monitor via cable with the PC.

### 6. Comparison to the 510(k) Cleared Device (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. Wrist 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. They use semiconductor pressure sensor instead of capacitive pressure sensor to translate the pressure variations to electrical signals that can be interpreted by an integrating circuit. Moreover both devices have a MAM function.

The difference between BP3AX1-4U and the predicate device is the addition of a PC function. The device can be used in connection with your personal computer (PC) running the Microlife Blood Pressure Analyzer (BPA) software. The memory data can be transferred to the PC by connecting the monitor via cable with the PC.

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

Testing information demonstrating safety and effectiveness of the Microlife Wrist Watch Blood Pressure Monitor, Model BP3AX1-4U 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:

- a. Reliability Test StorageTest
- b. Reliability Test - Operating Test

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

- Reliability Test Vibration Test ﻥ
- d. Reliability Test Drop Test
- e. Reliability Test Life Test
- f. EMC Test
- g. PC-link software BPA Test

None of the testing demonstrated any design characteristics that violated the requirements of the Reviewer Guidance or resulted in any safety hazards. It was our conclusion that the Microlife Wrist Watch Automatic Blood Pressure Monitor, Model BP3AX1-4U tested met all relevant requirements of the aforementioned tests.

### 8. Discussion of Clinical Tests Performed:

ANSI/AAMI SP10-2002 "National Standard for Manual, Electronic or Automated Sphygmomanometers" testing was performed on our predicate device. All relevant sections were addressed and testing conducted. The BP3AX1-4U met all relevant requirements of this standard, as applicable to our modified device. Repeat testing was not performed for the modified device, as clinical testing results were not affected by the changes to the modified device.

### 9. Software information:

In keeping with current FDA policy on software level of concern, the modified device is consistent with a moderate level of concern. We provided software documentation in accordance with the FDA November 2005 document "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices ". Moreover, the subject device requires the use of off-the-shelf software to operate the PC-link function, and we met all required elements as outlined in FDA's "Off the Shelf Software Guidance Document".

### 10. Conclusions:

We have demonstrated that the Microlife Wrist Watch Blood Pressure Monitor, Model BP3AX1-4U, is as safe and effective as our predicate, the Microlife Wrist Watch Blood Pressure Monitor, Model BP3AX1 based on electrical, mechanical and environmental testing results as well as the FDA DCRND November 1993 Draft "Reviewer Guidance for Premarket Notification Submissions", and our "Risk Analysis", as supplied with this submission.
