MICROLIFE UPPER ARM AUTOMATIC DIGITAL BLOOD PRESSURE MONITOR, MODEL BP3MQ1-2D

{0}------------------------------------------------ ## Exhibit#1 # 510(k) SUMMARY # MAY 1 3 2008 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: k080337 ### 1. Submitter's Identification: Microlife Intellectual Property GmbH, Switzerland Espenstrasse 139 9443 Widnau / Switzerland Date Summary Prepared: Jan. 11, 2008 ### 2. Name of the Device: Microlife Upper Arm Automatic Digital Blood Pressure Monitor, Model BP3MQ1-2D ## Information for the 510(k) Cleared Device (Predicate Device): 3. a. Microlife Upper Arm Automatic Blood Pressure Monitor, Model BP3BT0-1, K#013485, Microlife Corporation, b. AfibAlbert™ , K#052767, Lechnologies Research, Inc. ## 4. Device Description: Microlife Upper Arm Automatic Digital Blood Pressure Monitor, Model BP3MQ1-2D 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". The device detects the appearance of atrial fibrillation during measurement and the atrial fibrillation symbol "~ " is displayed on the LCD screen if any atrial fibrillation signal has been detected. page 1 OF 4 {1}------------------------------------------------ # 5. Intended Use: The Microlife Upper Arm Automatic Digital Blood Pressure Monitor, Model BP3MQ1-2D is a device intended to measure the systolic and diastolic blood pressure and pulse rate of an adult individual by using a non-invasive oscillometric technique in which an inflatable cuff is wrapped around the upper arm. The device detects the appearance of atrial fibrillation during measurement and gives a warning signal with the reading once the atrial fibrillation is detected. ### 6. Comparison to the 510(k) Cleared Device (Predicate Device): The modified device model BP3MQ1-2D and the predicate device model BP3BT0-1 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 by a factory set bleed valve and the deflation pressures are transferred via tubing to a sensor. The solely differences between the two models are the additional features such as atrial fibrillation detection function. However, the difference does not affect the accuracy and normal use of this device. Atrial fibrillation detection function of BP3MQ1-2D is similar with what is used in predicate device AfibAlbert™, with 510(k) cleared number K#052767. The input data from the blood pressure signals (data) from BP3MQ1-2D will produce a substantially equivalent outcome as the predicate AfibAlert™ getting the input data from an ECG signal (data). They are processed by an algorithm and both output atrial fibrillation diagnositic information. ## 7. Discussion of Non-Clinical Tests Performed for Determination of Substantial Equivalence are as follows: Testing information demonstrating safety and effectiveness of the Microlife Upper Arm Automatic Digital Blood Pressure Monitor, Model BP3MQ1-2D 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: - Reliability Test Storage test a. - Reliability Test Operating test ﻘ - C. Reliability Test - Vibration test - Reliability Test Drop test d. - Reliability Test Life test e. - EMC Test ಿ - g. IEC 60601-1 Safety 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 page 2 of 4 {2}------------------------------------------------ our conclusion that Microlife Upper Arm Automatic Digital Blood Pressure Monitor, Model BP3MQ1-2D tested met all relevant requirements of the aforementioned tests. ### 8. Discussion of Clinical Tests Performed: For clinical validation the atrial fibrillation function, AfibAlert™ algorithm was tested using published available annotated MIT-BIH AFIB database, which showed a 92% sensitivity value and a 96% specificity value. The BP3MQ1-2D was tested in two clinical trials which compared the atrial fibrillation (AF) readings from the BP3MQ1-2D to the rhythm determined by an electrocardiogram(ECG). The studies, Trial of Regular versus Irregular Pulse to Prevent Stroke (TRIPPS) 1.0 and 1.1, enrolled 205 and 157 subjects, respectively. All subjects in TRIPPS 1.0 and all, but one subject, in TRIPPS 1.1 had three atrial fibrillation readings performed with the BP3MQ1-2D. The results comparing the BP3MQ1-2D readings to the ECG readings read in a blinded fashion are shown in the table 1. The BP3MQ1-2D detected atrial fibrillation with a sensitivity ranging from 93% to 98% and a specificity ranging from 82-88%. | BP3MQ1-2D reading | ECG reading | | Sensitivity | Specificity | |-------------------|-------------|--------|-------------|-------------| | | AF | Non-AF | | | | TRIPPS 1.0 | | | 98.1% | 88.2% | | AF | 156 | 54 | (96-99%) | (85-91%) | | Non-AF | 3 | 402 | | | | TRIPPS 1.1 | | | 92.9% | 81.7% | | AF | 92 | 68 | (88-98%) | (78-86%) | | Non-AF | 7 | 303 | | | | Combined | | | 96.1% | 85.2% | | AF | 248 | 122 | (94-98%) | (83-88%) | | Non-AF | 10 | 705 | | | Table 1. Results for individual readings by the device compared to ECG. The last two columns show the sensitivity and specificity and the 95% confidence intervals in parentheses. In a second analysis of these results, the three sequential readings done in each subject were used to determine a single final reading based on which reading was most frequent. Thus if two or all three of the readings for a given patient showed atrial fibrillation then the combined final reading was atrial fibrillation. If none or only one of the three readings showed atrial fibrillation then the combined final reading PAGE 3 OF 4 {3}------------------------------------------------ was not atrial fibrillation. The results of this analysis is shown in the table 2. Using the combined three sequential readings, the BP3MQ1-2D detected atrial fibrillation with a sensitivity ranging from 94% to 100% and a specificity ranging from 85-90%. | BP3MQ1-2D reading | ECG reading | | Sensitivity | Specificity | |-------------------|-------------|--------|-------------|-------------| | | AF | Non-AF | | | | TRIPPS 1.0 | | | 100.0% | 89.5% | | AF | 53 | 16 | (92-100%) | (83-94%) | | Non-AF | 0 | 136 | | | | TRIPPS 1.1 | | | 93.9% | 85.4% | | AF | 31 | 18 | (78-99%) | (78-91%) | | Non-AF | 2 | 106 | | | | Combined | | | 97.7% | 87.7% | | AF | 84 | 34 | (91-100%) | (83-91%) | | Non-AF | 2 | 242 | | | Table 2. Results for the three sequential readings combined compared to the ECG. The last two columns show the sensitivity and specificity and the 95% confidence intervals in parentheses. Based upon the aforementioned information, the requirement to develop an atrial fibrillation detection module for the BP3MQ1-2D to detect atrial fibrillation that is added to the existing firmware included in the BP3BT0-1 has been met. ### Software information: a. Software validation was conducted in accordance with a moderate level of concern designation in accordance with the FDA November 2005 document, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices". ## 10. Conclusions: It has been demonstrated that there is no difference between the Microlife Upper Arm Automatic Digital Blood Pressure Monitor Model BP3MQ1-2D and the predicate model BP3BT0-1 in terms of safety and effectiveness based on electrical, mechanical and environmental test results, the FDA DCRND November 1993 Draft "Reviewer Guidance for Premarket Notification Submissions", and the ANSI/AAMI Voluntary Standard, SP10: 2002 test results. {4}------------------------------------------------ Public Health Service Image /page/4/Picture/2 description: The image shows the seal of the Department of Health & Human Services (HHS).
