Intended Use
The Pure Flow External Counter-Pulsation 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, increased blood flow. It is intended for use under the oversight of a healthcare professional.
Device Description
The Pure Flow External Counter-Pulsa-tion device is a mechanical device used to increase aortic pressure during early native heart diastole to augment myocardial perfusion, and to decrease aortic pressure during early native heart systole to reduce ventricular workload and vascular afterload. The PureFlow consists of a main unit, and applied parts (computer monitor, keyboard, flexible tubes which connect to fabric cuffs, inside each cuff is an inflatable plastic balloon), EKG wires, and SpO2 sensors. PureFlow works on the basis of external counter pulsation. The pressure is created by inflating a series of cuffs (similar to blood-pressure cuffs) that squeeze the extremities (calf's, thighs, buttocks) forcing blood back up to the heart on each heart cycle. This process ultimately restores (by force) sufficient blood flow to parts of the heart that is lacking oxygen. The treatment process generally spans for a period of 1 hour each day for a period of 35 total treatments. ECP Treatment is proven to develop existing pathways of oxygenated blood back to the heart muscle. In other words, External Counterpulsation Therapy restores pathways for adequate & necessary blood flow back to heart through vessels that already exist. The device also utilizes the following cleared components: Cable/Lead wire (ECG/EKG, SpO2, and Invasive Blood Pressure): K120010 LNCS/M-LNCS Oximetry Sensor: K101896
More Information

No
The description focuses on the mechanical and physiological principles of external counter-pulsation and does not mention any AI or ML components or functionalities.

Yes

The device is intended for the "treatment of chronic stable angina" and "to provide improvement in vasodilation, increased blood flow," which are therapeutic applications.

No

Explanation: The device description states it is a mechanical device used for treatment, specifically to improve blood flow to the heart and reduce ventricular workload. Its intended use is for treating chronic angina and improving vasodilation/blood flow in healthy patients. It does not mention diagnosing conditions.

No

The device description explicitly states it is a "mechanical device" and lists several hardware components including a main unit, computer monitor, keyboard, flexible tubes, fabric cuffs with inflatable balloons, EKG wires, and SpO2 sensors. It also mentions utilizing cleared hardware components like cables and sensors.

Based on the provided information, the Pure Flow External Counter-Pulsaion device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
  • Pure Flow Function: The Pure Flow device is a mechanical device that applies external pressure to the extremities to influence blood flow within the body. It works by physically manipulating the circulatory system.
  • Lack of Specimen Analysis: The description does not mention the device analyzing any biological specimens. Its function is entirely external and mechanical.

Therefore, the Pure Flow device falls under the category of a therapeutic or physiological support device, not an IVD.

There are no differences between the subject device and the predicate device with respect to indications and intended use. Electrical safety and EMC testing was performed per IEC 60601 on the subject device. The device passed the testing, just as the predicate device did. Thus, in electrical safety and EMC testing, the devices are equivalent.

The difference in the length of the device is only a design preference. Renew has decided to incorporate a built in treatment bed. The core dimension of the machine are the same. The additional length of the unit is due to the extension of the bed components, which have no therapeutic or functional effect on the treatment. Our device can be wheeled bedside to the patient who can lie comfortably on specialized beds if required.

The increased weight of PureFlow, as compared to the predicate, is due to the materials used for the shell of the housing of the unit. It weighs approximately 18kg more but this has no direct effect on the clinical application.

No biocompatibility testing was conducted on PureFlow, as none of its components or parts are intended to touch the skin. The cuffs of the device are intended to be used on top of clothing. The device will only use 510(k) cleared ECG electrodes and pulse oximeters.
