1. A method for capturing a thrombus with a catheter and a stent which is inserted in and pushed out of the catheter, the stent being configured to be pushed out of the catheter to unfold while rotating and swinging when the stent is pushed out of the catheter in a state of being unrestrained, the method comprising:
pushing the stent out of the catheter inside a blood vessel; and
capturing a thrombus,
wherein the stent includes:
a plurality of first bodies of a first pattern, each first body having a first element, an adjacent pair of the first bodies being arranged so as to share only a part of the first element thereof; and
a plurality of second bodies of a second pattern interconnected with the first bodies, each second body having a second element, an adjacent pair of the second bodies being arranged so as to share only a part of the second element thereof,
wherein each of the plurality of first bodies is configured to share a common part with at least one of the plurality of second bodies so as to be adjacent to each other,
wherein the first bodies and the second bodies are respectively arranged in a circular direction that is inclined by an inclination with respect to a circumferential direction perpendicular to a direction of a longitudinal axis of the stent in a deployed state of the stent, thereby the first element of the first bodies and the second element of the second bodies are wound about the longitudinal axis of the stent in a spiral manner in a tubular state of the stent, and
wherein a winding direction of the first element is opposite to a winding direction of the second element with respect to the longitudinal axis of the stent, such that a deformation in a radial direction due to a distortion load is suppressed.
