Intended Use

The Microlife Upper Arm Blood Pressure Monitor, Model BP-3BT0-AP, 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 cives a warning signal with the reading once the irregular heartbeat is detected.

Device Story

Non-invasive blood pressure monitor; uses inflatable upper arm cuff; electronic capacitive pressure sensor converts cuff pressure variations to electrical signals; oscillometric method determines systolic/diastolic pressure and pulse rate; detects irregular heartbeats and provides warning signal. Intended for adult use; operated by patient or clinician. Output displayed to user to assist in monitoring cardiovascular health.

Clinical Evidence

No clinical validation required for blood pressure measurement as algorithm is identical to predicate BP-3BT0-1. Simulator comparison study conducted to validate irregular heartbeat detection function. Bench testing performed per FDA November 1993 Draft Reviewer Guidance, including electrical, mechanical, environmental, reliability (drop, storage, vibration), EMC, and IEC 60601-1 safety testing.

Technological Characteristics

Capacitance-type pressure sensor; oscillometric measurement principle; electronic integrating circuit; split slope resolution software algorithm; non-invasive inflatable cuff; powered by internal batteries (implied); standalone device.

Indications for Use

Indicated for adult individuals to measure systolic/diastolic blood pressure and pulse rate via non-invasive upper arm cuff; includes irregular heartbeat detection.

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 5l0(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: K0414) /

## 1. Submitter's Identification:

Microlife Intellectual Property GmbH, Switzerland Max Schmidheiny-Strasse 201 9435 Heerbrugg / Switzerland

Date Summary Prepared: May 26, 2004

Contact: Mr. Gerhard Frick

## 2. Name of the Device:

Microlife Blood Pressure Monitor, Model BP3BT0-AP

## 3. Predicate Device Information:

The Microlife Upper Arm Automatic Blood Pressure Monitor. Model BP-3BTO-AP is substantially equivalent to the Microlife Automatic Blood Pressure Monitor. Model BP-3BT0-1, K# 013485, and, the A&D Medical Lifesource Blood Pressure Monitor, Model UA-787V, K#012472.

## 4. Device Description:

The Microlife Upper Arm Automatic Blood Pressure Monitor, Model BP-3BTO-AP 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 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".

## റ Intended Use:

The Microlife Upper Arm Blood Pressure Monitor, Model BP-3BT0-AP, 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 cives a warning signal with the reading once the irregular heartbeat is detected.

## 6. Comparison to Predicate Devices:

Both the subject device and Microlife predicate use the well known oscillometric method within the software algorithm to determine the systolic and diastolic blood pressure and pulse rate. Both devices use a similar capacitance-type pressure sensor to translate the pressure variations to electrical signals that can be interpreted by an integrating circuit. For both devices, the software is capable of a split slope resolution to improve accuracy over the entire range. The subject device differs from the Microlife predicate in the irregular heartbeat detection function.

Both the subject device and the A&D Medical Lifesource predicate have the same indications for use. Both devices include an irregular heartbeat detection function. Both the subject device and the A&D Medical Lifesource predicate use the well known oscillometric method within the software algorithm to determine the systolic and diastolic blood pressure and pulse rate.

## 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 BP3BT0-AP 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.

KO-1411 p. 313

- Reliability Test Operation Conditions b.
- Reliability Test Drop Testing C.
- Reliability Test Storage d.
- Reliability Test Vibrating Testing e.
- (. EMC Test
- IEC 60601-1 Safety Test ப்.

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 Automatic Blood Pressure Monitor, Model BP-3BT0-AP tested met all relevant requirements of the aforementioned tests.

### 8. Discussion of Clinical Tests Performed:

Since the blood pressure measuring algorithm in this device is exactly the same as in the predicate device, BP3BT0-1, no clinical validation for blood pressure measurement is required. Instead, we conducted a simulator comparison study for the function of irreqular heartbeat detection.

#### 9. Conclusions:

We have demonstrated that the Microlife Automatic Blood Pressure Monitor, Model BP3BT0-AP, is as safe and effective as the predicate, the Microlife Automatic Blood Pressure Monitor, Model BP-3BT0-1, and, the A&D Medical Lifesource, based on electrical, mechanical and environmental testing results as well as the FDA DCRND November 1993 Draft "Reviewer Guidance for Premarket Notification Submissions", and, the ANSI/AAMI Voluntary Standard, SP10-1992 testing results.
