A. Introduction
A.1 How Does the Movement and Compressions System Work?
The Movement and Compressions System works by providing intermittent
compressive forces to the legs, increasing the blood flow in the veins, moving blood
towards the direction of the heart and reducing the risk of clot formation.
To perform intermittent compression for DVT Prophylaxis, a single-patient use
disposable fabric moisture wicking strap (MAC Strap) is wrapped around a patient’s
calf muscle just below the knee. The controller is attached to the strap in two
places; the strap mounts and securement ring (see Figure 2). Inside the controller is
a small DC motor that moves the securement ring in and out of the controller, thus
contracting and retracting the strap. When the strap is contracted, compression is
applied to the patient’s calf muscle. When the strap is retracted, compression force
is released to the patient’s calf muscle. This provides the blood flow ‘pumping’
action once per minute that prevents blood clots from forming.
Based upon this mode of action, the MAC System™ uses mechanical force to
provide intermittent compression, not pneumatic force. The system does not
require a powered air supply, so the risk of aerosolization of potential contaminants
or germs is mitigated as there is no blowing air. Also, the device components are
either disposable (the MAC Strap) or the surfaces are easily disinfected (MAC
Controller and Charging Hub) allowing for ease of cleaning and mitigation of cross-
contamination. There are no air connections or pneumatic pumps to clean
between patients.
A.2 Intended Use & Indications for Use
The Movement and Compressions System is intended to be a portable and
wearable system, prescribed by healthcare professionals, to treat the following
conditions by stimulating blood flow in the legs:
• Aid in the prevention of DVT (deep vein thrombosis);
• Enhance blood circulation;
• Diminish post-operative pain and swelling;
• Reduce wound healing time;
• Aid in the treatment and healing of: stasis dermatitis, venous stasis ulcers,
arterial and diabetic leg ulcers, chronic venous insufficiency, chronic
lymphedema, and reduction of edema in the lower limbs;
