An alienated thrombus capture device 1 has a ring portion 12 made of a wire member having foldable elasticity, an flexibly transformable linear stiffener portion 11 that penetrates the ring portion 12, a porous bursiform portion 13 whose opening edge portion 13a is mounted on the ring portion 12 and whose closed edge portion 13b is mounted on a part of a distal end side of the stiffener portion 11, and flexibly transformable support linear member portion 14 that is supported between the stiffener portion 11 and the ring portion 12 in a strained state. The support linear member portion 14 supports the ring portion 12 in a spread state with a distance between a support portion 14a on the stiffener portion 11 and a circumference of the ring portion 12 kept generally constant at least in a state that the ring portion 12 is spread.
