Vascular lesion model

A vascular lesion model, comprising:

• a blood vessel portion having a hollow shape and configured to simulate a blood vessel;
• and
• a lesion portion arranged inside the blood vessel portion and divided into a plurality of lesion regions each having a different hardness, at least a part of lesion regions among the plurality of lesion regions being formed from a polymer material,
• wherein the lesion portion includes, as the at least the part of the lesion regions, at least one type of lesion region selected from the group consisting of:
• a first lesion region arranged to contact a part of an inner periphery of the blood vessel portion in a cross section perpendicular to a longitudinal direction of the vascular lesion model and having a shape that extends from the part of the inner periphery toward a center of the lesion portion,
• a second lesion region having a solid shape separated from an outer periphery of the lesion portion in both a cross section perpendicular to the longitudinal direction and a cross section parallel to the longitudinal direction,
• a third lesion region arranged separated from both ends of the lesion portion in the longitudinal direction and configured to occlude the blood vessel portion, and
• a plurality of fourth lesion regions provided separated from the inner periphery of the blood vessel portion in a cross section perpendicular to the longitudinal direction, and arranged independently and separately from one another.
