The Overlay works with most suspension methods, such as suspension sleeves, passive and active vacuum, and distal attachment.
As for now, we don’t have a large sample size of enough users with an active vacuum system; therefore, we cannot confirm and assure the efficiency and synergy of the overlay with that type of suspension system.
That said, the patients currently using the Overlay with an active vacuum system enjoy their Overlay as much as the other type of patient. Also, the Overlay might not be suitable for all patients with a supracondylar socket (the data on the compatibility with this type of system is insufficient).
Finally, this device can’t be used on patients with leather thigh straps (Cuffs, Straps and Belts) if they interfere with the pump or valve of the Overlay.
Patients with a sleeve that includes a sealing ring can use the device, however, sometimes the ring takes significant space on the residual limb, and this space, if too proximal, may interfere with the Overlay. In these particular cases, it will be necessary to ensure that all the air cells are inside the socket and that the product does not come into contact with the sealing ring.
