Regulatory Classification

Identification

(2) Class III (premarket approval) for the following intended uses: Unstable angina pectoris; acute myocardial infarction; cardiogenic shock; congestive heart failure; postoperative treatment of patients who have undergone coronary artery bypass surgery; peripheral arterial disease associated with ischemic ulcers rest pain or claudication, threatened gangrene, insufficient blood supply at an amputation site, persisting ischemia after embolectomy or bypass surgery, and/or pre- and post-arterial reconstruction to improve runoff; diabetes complicated by peripheral arterial disease or other conditions possibly related to arterial insufficiency including nocturnal leg cramps and/or necrobiosis diabeticorum; venous diseases, including prophylaxis of deep vein thrombophlebitis, edema (e.g., chronic lymphedema) and/or induration (e.g., stasis dermatitis) associated with chronic venous stasis, venous stasis ulcers, and/or thrombophlebitis; athletic injuries, including Charley horses, pulled muscles and/or edematous muscles; necrotizing cellulitis. (c) *Date premarket approval application (PMA) or notice of completion of product development protocol (PDP) is required.* A PMA or notice of completion of a PDP is required to be filed with FDA on or before March 31, 2014, for any external counter-pulsating device, with an intended use described in paragraph (b)(2) of this section, that was in commercial distribution before May 28, 1976, or that has, on or before March 31, 2014, been found to be substantially equivalent to any external counter-pulsating device, with an intended use described in paragraph (b)(2) of this section, that was in commercial distribution before May 28, 1976. Any other external counter-pulsating device with an intended use described in paragraph (b)(2) of this section shall have an approved PMA or declared completed PDP in effect before being placed in commercial distribution.

### Predicate Device Information 4.

K023701. The Mobile External Counter Pulsation System AngioNew-IV Living Data Technology Corporation, Brooklyn, NY

### ട. Device Description

The Mobile External Counter Pulsation System AngioNew-V is a mobile noninvasive external counter pulsation device for the treatment of patients suffering from congestive heart failure, stable or unstable angina pectoris, acute myocardial infarction and cardiogenic shock.

The Living Data Technology AngioNew-V system consists of a central control unit and three pairs of inflatable cuffs that are wrapped respectively around a patient's calves, thighs and buttocks. External pressure is applied via the cuffs to the lower extremities of the patient in synchronization with the heartbeat. When the heart is in the relaxed state during diastolic period, pressure is applied sequentially from the distal to proximal extremities to force blood back to the heart, increase coronary perfusion pressure (diastolic augmentation) and, at the same time, increases coronary blood flow and enhances the development of

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

coronary collateral circulation. Just before the heart starts ejecting blood during systolic period, air is quickly withdrawn from all cuffs simultaneously to remove all the external applied pressure, leaving behind empty vasculature in the lower extremities to receive the output of the heart, thereby reducing systolic pressure (systolic unloading) and the workload of the heart.

### Indications for Use 6.

The Mobile External Counter Pulsation System AngioNew-V is a mobile noninvasive external counter pulsation device for the treatment of patients suffering from congestive heart failure, stable or unstable angina pectoris, acute myocardial infarction and cardiogenic shock.

### Comparison to Predicate Device 7.

The modified device AngioNew-V is essentially same in specifications as well as in technological and functional characteristics as the current device AngioNew-IV (cleared under K023701), except for the following technological upgrading:

- A control loop is added to the AC drive regulate the compressor motor for . stabilizing the air reservoir pressure.
- A finger pulse plethysmography sensor is employed and the original . temporal artery pressure sensor is optional now.
- The central control unit CPU is upgraded. The display is also upgraded . from 9" CRT to 8.4" LCD.
- The quick connectors between cuffs and valves are improved with . integrated senor to identify cuff connection sequence so that the machine adjusts inflation sequence accordingly, therefore adding an additional safety feature to the device.
- A new inflation timing adjustment method for better counter pulsation . effect is used in AngioNew-V. Using a predetermined, heart rate dependent inflation timing as the initial value, the software updates the inflation timing to maximize counterpulsation effect.
- A finger oximetry sensor is added to provide measurement and display of . blood oxygen saturation level.
- A built-in printer is added to the device to provide real time recording of . ECG and pulse wave, as well as other information such as heart rate, D/S ratios, etc., during ECP treatment.

### 8. Discussion of Non-clinical Tests Performed for Determination of Substantial Equivalence

In addition to safety tests in accordance with IEC 60601-1 and EN 60601-1; EMC tests in accordance with IEC 60601-1-2, EN 55011, EN 61000-3-2, and EN 61000-3-3; other testing was also conducted, such as:

etc.

It is concluded that AngioNew-V meets all safety and EMC requirement, as well as all design specifications. Therefore it is substantially equivalent to AngioNew-IV in safety and effect.

#### ਹੈ. Conclusions

The subject device, AngioNew-V, has the same intended use and similar characteristics as the predicate device. Moreover, bench testing contained in our submission and non-clinical testing supplied demonstrate that there are no differences in their technological characteristics, thereby not raising any new Thus, the AngioNew-V device is questions of safety or effectiveness. substantially equivalent to the predicate device.
