Intended Use

The AviaFit™ Device is intended for use to help prevent the onset of DVT in patients by stimulating blood flow in the legs (simulating muscle contractions). Furthermore, the unit can be used as an aid in the prophylaxis for DVT by persons traveling, or those expecting to be stationary for long periods of time (> 4 hours). This device can also be used to aid in the prevention of DVT, enhance blood circulation, diminish post-operative pain and swelling, reduce wound healing time, and aid in the treatment and healing of: stasis dermatitis, venous stasis ulcers, arterial and diabetic leg ulcers, chronic venous insufficiency, and reduction of edema in the lower limbs.

Device Story

Portable, battery-operated, calf-mounted device; uses mechanical intermittent compression to simulate muscle contractions. Control unit contains motor, gears, springs, and microprocessor; tugs and releases leg strap to exert pressure on tissue, aiding venous return. Operates in cycles of active pressure followed by release. Used by patients to prevent DVT, reduce edema, and treat leg ulcers. Healthcare providers or patients use device to improve circulation and reduce post-operative pain/swelling. Benefits include reduced DVT risk and accelerated wound healing.

Clinical Evidence

No clinical data. Non-clinical performance testing verified device meets design and performance specifications.

Technological Characteristics

Battery-operated, portable, calf-mounted device. Components: plastic control unit, leg strap, motor, gears, springs, microprocessor. Mechanism: mechanical intermittent compression. Connectivity: standalone. Sterilization: not specified.

Indications for Use

Indicated for patients requiring DVT prophylaxis, enhanced blood circulation, or treatment of venous/arterial/diabetic ulcers, stasis dermatitis, chronic venous insufficiency, and lower limb edema. Suitable for travelers or individuals stationary for >4 hours.

Regulatory Classification

Identification

A compressible limb sleeve is a device that is used to prevent pooling of blood in a limb by inflating periodically a sleeve around the limb.

Predicate Devices

• AviaFit™ Device (K071744)

#### Establishment Registration No .:

3005003051

#### Classification Name:

Compressible Limb Sleeve (21 CFR 870.5800, Product Code JOW)

#### Classification:

FDA has classified Compressible Limb Sleeve devices as Class II devices (product code JOW), which are reviewed by the Cardiovascular Devices Panel.

11720

g 208 3

#### Predicate Device:

The AviaFit™ Device is substantially equivalent to the originally cleared AviaFit™ Device (also manufactured by FlowMedic Ltd. and the subject of 510(k) document no. K071744) and the DVTcare CA5 device (manufactured by Doctor's Orders Inc. and the subject of 510(k) document no. K061125).

#### Device Description:

The FlowMedic AviaFit™ is a battery operated portable device integrating a patented mechanical intermittent compression technology to improve blood circulation in the lower limbs and reduce the risk of deep vein thrombosis, edema and leg discomfort during limited mobility conditions. The device is comprised of an actuator and is externally mounted on the calf.

The anatomical concave shaped control unit is connected to the leg strap and applied to the calf. Using an innovative low power consumption mechanism, the system tugs and releases the leg strap placed around the calf muscle, thus exerting intermittent cycles of external pressure build-up on the tissue, and a subsequent release, thus aiding venous return. Strap tug and release are controlled by a system of gears, springs, a motor and integrated microprocessor contained in the plastic control unit.

The device mimics the muscle activity during walking by acting sequentially in cycles of an active interval of exerting pressure on the muscle, thus augmenting blood flow. followed by a loose state for a period of time, allowing blood flow to return to the limb.

#### Intended Use / Indication for Use:

The AviaFit™ Device is intended for use to help prevent the onset of DVT in patients by stimulating blood flow in the legs (simulating muscle contractions). Furthermore, the unit can be used as an aid in the prophylaxis for DVT by persons traveling, or those expecting to be stationary for long periods of time (> 4 hours). This device can also be used to aid in the prevention of DVT, enhance blood circulation, diminish post-operative pain and

swelling, reduce wound healing time, and aid in the treatment and healing of: stasis dermatitis, venous stasis ulcers, arterial and diabetic leg ulcers, chronic venous insufficiency, and reduction of edema in the lower limbs.

#### Comparison of Technological Characteristics with the predicate device:

The technological characteristics of the AviaFit™ device are similar to the technological characteristics of the predicate devices including mechanism of action (e.g., compression to simulate muscle contraction), pressure range of compression time and cycle time, treatment site, indicators, power requirements, etc.

#### Non-Clinical Performance Data and Performance Standards

The performance tests performed on the original, cleared and identical AviaFit™ device verified that the operating characteristics and performance of the device are in accordance with its specifications.

#### Clinical Performance Tests:

Not Applicable.

#### Conclusions Drawn from Non-Clinical and Clinical Tests:

The non-clinical tests demonstrated that the AviaFit™ device meets its design and performance specifications.

#### Substantial Equivalence:

The AviaFit™ device has the same intended use as the DVTcare CA5 device. Furthermore, the AviaFit™ device has the same technological characteristics, (i.e., same mechanism of action, and similar design and specifications) as the originally cleared AviaFit™ device and the DVTcare CA5 predicate device. The differences in the new device do not raise new issues of safety or effectiveness. In conclusion, the modified AviaFit™ device is substantially equivalent to the predicate devices and therefore, may be cleared for marketing in the United States.
