Fig 1 BioVAD schematic. Pump chamber. (A) Conditions of absent venous return, in which the pump chamber is flat (inlet pressure = 0). (B) Conditions of sufficient venous return with expansion of the pump chamber (inlet pressure > 0). (a = pump chamber; b = roller; c = rotor; d = pump chamber inlet region; e = pump chamber outlet region.)
