Indications for Use

The ManaFlow system, part numbers MFLOW51 and MFLOW52, is comprised of a gradient compression sleeve and a portable intermittent pump to provide graduated compression in both sustained and intermittent settings for use in both the hospital and outpatient setting. ManaFlow 51 is pre-set to the default setting of 50 mmHg and cannot be adjusted, whereas the ManaFlow 52 can be adjusted by the physician to a pressure within the specified range. It is intended for use in: - Treatment of lymphedema - Treatment of chronic venous insufficiency - Treatment and promotion of healing of stasis dermatitis and venous stasis ulcers - Reducing venous leg ulcer healing time - Reducing edema due to venous stasis - Enhancing venous return The device is intended for home, and hospital use.

Device Story

ManaFlow is a portable, rechargeable, prescription-only intermittent pneumatic compression system for home and hospital use. It consists of a control unit with an air pump and an inflatable sleeve with multiple air chambers. The device is operated by a physician or patient; the user initiates the cycle via an ON/OFF button. The system inflates the cuff to a default (50 mmHg) or physician-adjusted pressure, then deflates to ambient pressure during a rest period. This cyclic inflation/deflation mimics muscle contractions to enhance venous return, treat lymphedema, and reduce edema. The control unit monitors pressure via an internal switch and software, providing audible and visual alarms for system faults. The output is mechanical compression of the limb, which aids in blood circulation and promotes healing of venous ulcers. The device benefits patients by providing portable, automated compression therapy to manage edematous conditions and prevent DVT.

Clinical Evidence

Bench testing only. No clinical data provided. Validation included electrical safety (ANSI AAMI ES60601-1), electromagnetic compatibility (IEC 60601-1-2), and software verification per FDA guidance.

Technological Characteristics

Portable, rechargeable electromechanical device. Components: plastic-housed control unit, inflatable multi-chamber cuff (soft medical fabric). Sensing: internal pressure switch. Energy: internal rechargeable battery or AC adapter. Connectivity: standalone. Sterilization: supplied clean, non-sterile. Software: microprocessor-controlled pump cycles. Biocompatible materials.

Indications for Use

Indicated for patients requiring venous return and lymphedema treatment, including chronic venous insufficiency, stasis dermatitis, venous stasis ulcers, and edema due to venous stasis. Contraindicated for patients with suspected/active/untreated deep vein thrombosis (DVT), ischemic vascular disease, severe arteriosclerosis, pulmonary edema, severe congestive heart failure, thrombophlebitis, active infection, or on legs where cuffs interfere with conditions like gangrene, open wounds, or recent skin grafts.

Description of Subject Device The ManaFlow system, part numbers MFLOW51 and MFLOW52, is a portable and rechargeable prescriptive device. It is intended to be used in the home or clinical/hospital setting by or under the direction of a medical professional to apply pressure to treat lymphedema and other edematous conditions and to prevent Deep Vein Thrombosis (DVT). The ManaFlow, supplied clean and non-sterile, utilizes the pneumatically controlled cuff actuated by an electronically controlled air pump unit. All pump, battery and control components are protectively {4}------------------------------------------------ housed in a plastic case of the control unit that is attached to an inflatable cuff/sleeve. An ON/OFF button, a SET button, and a display provide for user interface. There is also a port for connecting the battery charger/AC adapter plug. The cuff component consists of multiple (four or so) air chambers/bladders encased inside a soft medical fabric or equivalent medical for increased patient comfort and biocompatibility compliance. In operation, the user simply turns the power on via the ON/OFF button. A cuff containing air chambers/bladders is connected to the control unit. And the control unit then inflates the cuff to the default pre-determined pressure (50 mmHg), which could be adjusted/calibrated via the SET button. The cuff pressure is monitored by an internal pressure switch and system software. Once the cuff pressure of the multiple air chambers/bladders reaches the pre-determined or adjusted level, the pump is turned OFF for a rest period, and the cuff deflates to ambient pressure through a valve inside the plastic case. After the rest period, the cycle of inflation and deflation repeats until the device is turned off. ## 5.
