The ALPS VIVA Sleeve has a built-in valve to evacuate air in the socket to provide superior security. It provides suction suspension without the need of creating a valve in the socket. Once the sleeve is donned the valve should be located proximal to the patella (above the knee cap) to create back pressure within knee flexion (the knee's range of flexing movement). The VIVA is made with ALPS GripGel which prevents the sleeve from rolling down on the patient’s limb. The sleeve is designed to minimize compression and irritation proximally on the thigh and knee joint.
