Abstract

This disclosure relates to methods of reversing blood flow using a blood flow reversal valve that includes a first member having a first passage and a second passage, and a second member having a first passage and a second passage. The first and second members are rotatably fixed relative to one another such that the first passage of the first member is aligned with the first passage of the second member and the second passage of the first member is aligned with the second passage of the second member. A flow directing element is disposed in the cavity and is moveable between a first position in which the first passage of the first member and the first passage of the second member are fluidly connected and a second position in which the first passage of the first member and the second passage of the second member are fluidly connected.
