Abstract: A residual limb prosthesis includes a socket for receiving a residual limb, the socket having a socket wall defining a limb-receiving surface. A coil-shaped channel extends through the socket wall from an inlet to an outlet, the outlet fluidly communicating with the ambient atmosphere. An air mover fluidly communicates with the inlet and the ambient atmosphere outside of the socket wall, the air mover drawing air from the ambient atmosphere and circulating the air through the coil-shaped channel to be exhausted at said outlet.
