Indications for Use
The ECP-MC3 device is intended for the treatment of chronic stable angina that is refractory to optimal anti-anginal medical therapy and without options for revascularization. In addition, it is intended for use in healthy patients to provide improvement in vasodilation, and increased blood flow. It is intended for use under the oversight of a healthcare professional.
Device Story
ECP-MC3 is a computer-controlled external counterpulsation system for non-invasive treatment of cardiovascular and ischemia-related diseases. Input data includes real-time ECG signals via electrodes and plethysmograph waveforms via finger clip sensor. System uses these inputs to synchronize the inflation/deflation of three pairs of air cuffs (calves, lower thighs, upper thighs/buttocks) with the patient's cardiac cycle. Cuffs inflate sequentially during diastole to increase diastolic blood pressure, coronary perfusion, and cardiac output; cuffs deflate before systole to reduce cardiac workload. Operated by healthcare professionals in clinical settings. Output consists of hemodynamic augmentation monitored via plethysmograph. Benefits include improved blood flow and vasodilation for patients with refractory angina or healthy individuals.
Clinical Evidence
No clinical data provided. Substantial equivalence supported by bench testing, including reliability testing, pressure control timing, pressure range accuracy, and electrical safety/EMC compliance (IEC 60601-1, 60601-1-2, 60601-1-6, 60601-1-8).
Technological Characteristics
Computer-controlled pneumatic system; three-pair cuff assembly (calves, lower thighs, upper thighs/buttocks). Sensing: ECG electrodes and finger plethysmograph. Connectivity: Standalone. Power: AC 120V/60Hz. Standards: IEC 60601-1, IEC 60601-1-2, IEC 60601-1-6, IEC 60601-1-8, GB 10035-2017. Software: Moderate level of concern.
Indications for Use
Indicated for patients with chronic stable angina refractory to optimal medical therapy without revascularization options, and healthy patients seeking improved vasodilation and blood flow. Intended for use under healthcare professional oversight.

#### Device Description 4.
ECP-MC3 is the most updated designed External Counter Pulsation System for non-invasive treatment of certain cardiovascular and other ischemia related diseases.
The ECP-MC3 system is computer-controlled system that inflates and deflates three pairs of air cuffs in synchronization with the patient's cardiac cycle. The three pairs of cuffs are wrapped around the calves, lower thighs, and upper thighs/buttocks of the patients. As diastole begins, the cuffs inflate separately in sequence from the calves, to the lower thighs, to the upper thighs including the lower buttocks. This inflation sequence generates and impels a counter-pulsation wave, increasing diastolic blood pressure (diastolic augmentation), coronary perfusion pressure and coronary blood flow, and
{5}------------------------------------------------
raising cardiac output.
The start of inflation, deflation and cuff pressure can be adjusted by the operator. The system will deflate simultaneously before systole, this will reduce the heart's workload and resistance of blood vessel.
Before ECP treatment, ECG electrodes and Finger Clip plethysmograph Sensor are placed on the patient. The ECG waveform is used to generate triggering signals for cuff inflation and deflation. The plethysmograph waveform is used to monitor the proper timing of the inflation cycle and to indicate the effect of ECP treatment on patient homodynamic.
### 5. IntendedUse
The ECP-MC3 device is intended for the treatment of chronic stable angina that is refractory to optimal anti-anginal medical therapy and without options for revascularization. In addition, it is intended for use in healthy patients to provide improvement in vasodilation, and increased blood flow. It is intended for use under the oversight of a healthcare professional.

## Note 1
Although there is little difference for illustration about the indication for use, the description of the predicate device is more specified, yet their meanings are the same. This difference does not affect the safety and effectiveness.
## Note 2
Although the subject device does not provide with SPO2, since it is not provided with the function for monitoring SPO2; but the treatment is supervised by the qualified physician, so for the subject device's intended use, SPO2 is not mandatory and it will not affect the safety and effectiveness.
## Note 3
Although the device design and part of functional parameters between the predicate device and subject device are different, they are both complied with IEC 60601-1. So the minor differences on such parameters do not affect the safety and effectiveness.
## 9. Summary for clinical test
Clinical performance is not deemed necessary.
#### 10. Conclusion
{10}------------------------------------------------
The subject device External Counterpulsation System has all features of the predicate device for intended use.
Through the reliability testing, it demonstrate that the subject device is as effective and performs as well as the predicate device in its lifetime; And through the performance testing, the device was tested and demonstrated for its synchronization of therapy and pressure control accuracy.
