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 th e walled chamber. An actuating mechanism (10) peristaltically moves fluids through a micro conduit (56). The actuating mechanism includes a closed pock et (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 th e micro conduit thereby changing the volume of the conduit (56).
