Abstract: A micro-fluidic pump (22) has a pulsating micro chamber (46) which includes a walled chamber (50). The walled chamber further includes at least one pulsating portion (52) actuable to pulse and change an interior volume of the walled chamber. An actuating mechanism (10) peristaltically moves fluids through a micro conduit (56). The actuating mechanism includes a closed pocket (11) adjacent to the conduit. A flexible mechanism (18) defines a portion of a wall of the micro conduit (56). An expanding mechanism (14) which is understood to be a fluid is disposed within the pocket (11) for expanding a volume of the pocket and thereby flexing the flexible mechanism (18) into the micro conduit thereby changing the volume of the conduit (56).
