Date Summary Prepared: May 25, 2006

Contact: Mr. Gerhard Frick

#### 2. Name of the Device:

Microlife Upper Arm Automatic Digital Blood Pressure Monitor, Model BP3MC1- PC.

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

- a. Microlife Upper Arm Automatic Digital Blood Pressure Monitor, Model BP3BT0-AP, K#041411.
- b. Microlife Wrist Watch Automatic Blood Pressure Monitor, Model BP3BU1-5, K#021305.

#### Device Description: র্ব

Microlife Upper Arm Automatic Blood Pressure Monitor, Model BP3MC1- PC is designed to measure the systolic and diastolic blood pressure and pulse rate of an individual by using a non-invasive MAM (Microlife Average Mode) technique in which an inflatable cuff is wrapped around the Upper arm. Our method to define systolic and diastolic pressure is similar to the auscultatory method but uses an electronic capacitive pressure sensor rather than a stethoscope and mercury manometer. The sensor converts tiny alterations in cuff pressure to electrical signals, by analyzing those signals to define the systolic and diastolic blood pressure and calculating pulse rate, which is a well - known technique in the market called the "oscillometric method".

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

The device detects the appearance of irregular heartbeat during measurement, and the symbol " " " "is displayed after the measurement. In addition, 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.

#### ട്. Intended Use:

The Microlife Upper Arm Blood Pressure Monitor, Model BP3MC1-PC is a device intended to measure the systolic and diastolic blood pressure and pulse rate of an adult individual by using a non-invasive technique in which an inflatable cuff is wrapped around the upper arm.

The device detects the appearance of irregular heartbeat during measurement, and gives a warning signal with the reading once the irregular heartbeat is detected.

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. An upper arm 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. Moreover both devices have a pulse irregular heartbeat detection (IHD) function.

However the difference between BP3MC1- PC and the predicate devices are as follows:

### 1. MAM function:

BP3MC1- PC contains a switchable average mode in which the device automatically repeats 3 individual measurements cycles, each with a rest time of 15 seconds in between. After that the average of these 3 individual measurements is calculated and shown on the display. By certain key operation the user can access the individual results of the measurements.

### 2. 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.

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

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

Testing information demonstrating safety and effectiveness of the Microlife Automatic Blood Pressure Monitor, Model BP3MC1- PC 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. Moreover

The following testing was conducted:

- a. Reliability Test Storage test
- b. Reliability Test Operating test
- Reliability Test Vibration test C.
- d. Reliability Test Drop 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 Upper Arm Automatic Blood Pressure Monitor, Model BP3MC1- PC tested met all relevant requirements of the aforementioned tests.

#### Discussion of Clinical Tests Performed: 8.

ANSI/AAMI SP10-2002 "National Standard for Manual. Electronic or Automated Sphygmanometers" testing was performed. All relevant sections were addressed and testing conducted. The BP3MC1-PC 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".
