A thrombectomy apparatus and associated method that permit removal of a blood clot from a blood vessel utilize multiple segments (i.e., a first terminal segment and additional segment(s)), with each segment including magnetically responsive element(s) configured to cooperate with the at least one magnetic field supplied by magnetic field generator(s) arranged external to an animal body. Each segment includes projections expandable end portion(s) thereof, such that when adjacent segments are magnetically manipulated to press against one another (e.g., forming a mated segment assembly), the projections deflect outwardly and thereby increase a maximum width of the end portions. A method includes moving a terminal segment and at least one additional segment in one direction through a blood clot, pressing the segments against one another to expand terminal end segments and form a mated segment assembly, and moving the assembly in an opposing direction to engage and dislodge the clot.
