1 Preliminary In Vivo Testing of a Novel Pump for Short-Term Extracorporeal Life Support 
David J. Spurlock, MD, Kelly Koch, BS, Daniel E. Mazur, BS, Emilia M. Fracz, ME, Robert H. Bartlett, MD, Jonathan W. Haft, MD  The Annals of Thoracic Surgery  Volume 93, Issue 1, Pages (January 2012) DOI: /j.athoracsur Copyright © 2012 The Society of Thoracic Surgeons Terms and Conditions

2 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.)
