| Predicate Device | Manufacturer | 510(k)# |
|--------------------------------------------------------------|------------------|---------|
| DJS Massager; Recovery<br>Pump 701-E; Recovery Pump<br>701RA | MEGO AFEK AC LTD | K112479 |

#### I. Device Description

Powerpress Recovery Unit is a sequential pneumatic compression device designed to apply compression to a limb. The device is composed of two components.

{4}------------------------------------------------

- Pneumatic Manual / Analog Pump .
- . Limb Sleeve or garment composes of 4 chambers

Powerpress Recovery Unit enables different treatment pressure (30 ~ 100mmHg). When activated, air flows into chamber, the pump provides gradient pressurization to the chambers (sequential inflation of distal to proximal, with distal chambers inflated to a greater pressure than the proximal ones).

After each chamber is inflated, the pressure is held constant until all chambers are inflated, in order to prevent reverse gradient flow. Once all chambers are inflated, they are then all released simultaneously, and the cycle repeats. Pressure within chambers are adjustable pressure to chamber 1 is controlled by user-adjusted regulator on the pump. Pressure in chamber 2, 3 & 4 are individually lowered according to the default factory setting.

Gradient: appx 7%, example: Foot 60mmHg – Ankle 56mmHg – Calf 52mmHg - Thigh 48mmHg Cycle Time: Inflation 36 sec / Deflation 24 sec Inflation time each chamber : 1* chamber(foot) – 36 sec, 2nd chamber(ankle) – 27 sec, 3rd chamber(calf) - 18 sec, 4th chamber(thigh) - 9 sec

A calibrated dial gauge displays pressure in the range of 0 ~ 160 mmHg

- J. Substantial Equivalence of Technological Characteristics
Powerpress Recovery Unit Model PR1000 Massage Systems and the predicate device all provide sequential inflation pressure from distal to proximal segments. Both the Powerpress Recovery Unit and predicate devices offer adjustable pressure ranges.

The Powerpress Recovery Unit have decreasing gradient pressures from distal to proximal segments.while predicate device does not have decreasing gradient pressures. The Powerpress Recovery Unit provide continuously adjustable pressure in the range between 30 to 100 mmHg. while the predicate device provides three pressure adjustments options in increments of low, medium and high pressure ranges within the 20 to 80 mmHg range. The Powerpress Recovery Unit have fixed cycle times that are fixed by a motorized valve, and are independent of garment size and number (one or two garments). The predicate device does not have a motorized valve and uses back pressure to trigger the cycle to the next chamber of the garment.

A difference in the subject device from the predicate is that the Powerpress recovery unit has a pressure range from 30 mmHg to 100 mmHg while predicate device has from 20 mmHg to 80 mmHg. But there are FDA cleared devices for same intended use, which are shown in the table below, prove that our pressure range raises no new questions of safety and effectiveness. Also Electrical Safety Test (IEC 60601-1:2005+AMD1:2012) verifies that the technological differences in the fuse rating, power consumption, electric power plug, size and net weight of device do not raise different questions of safety and effectiveness.
