Blood Flow Reversal Valves and Related Systems and Methods

A method of reversing blood flow using a blood flow reversal valve that comprises a first member having a first passage and a second passage, a second member rotationally fixed relative to the first member and having a first passage and a second passage, and a flow directing element disposed in a cavity formed between the first and second members, the method comprising:

• moving the flow directing element of the blood flow reversal valve from a first position in which the first passage of the first member and the first passage of the second member are fluidly connected and the second passage of the first member and the second passage of the second member are fluidly connected to a second position in which the first passage of the first member and the second passage of the second member are fluidly connected and the second passage of the first member and the first passage of the second member are fluidly connected, wherein the first and second members of the blood flow reversal valve remain fixed with respect to one another while the flow directing element moves from the first position to the second position.
