The Simbex Active Contact System automatically and continuously maintains superior lower-limb prosthesis interface in response to periods of rest and activity. The Simbex Active Contact System automatically manages the fit of a lower limb suction socket by changing the volume of the socket in response to natural fluctuations of volume of the residual limb.
Simbex developed the Simbex Active Contact System™ and the Actiflow Circuit™ that automatically and continuously maintains a lower-limb prosthesis connection that is adapted for the normal, daily fluctuations of limb volume and the activity level of the user.
Activity generates the pumping action for the Actiflow Circuit™ to draw fluid from a reservoir and directs it to custom-fitted liners. At higher activity levels when the user needs more precise control of the prosthesis and the socket needs to be more secure, and the socket fit is less firm during periods of rest or while seated.
