Stent

A stent to be inserted into a catheter while being compressed radially, comprising:

• a plurality of corrugated pattern bodies having a corrugated pattern and arranged next to each other in an axial direction;
• and
• a plurality of connection elements arranged in a direction about an axis and connecting the corrugated pattern bodies adjacent to each other,
• wherein the corrugated pattern is formed of a plurality of corrugated units, each corrugated unit includes a first stem, a second stem, a third stem, a first top portion coupling a first end portion of the first stem on one side and a first end portion of the second stem on one side, and a second top portion coupling a second end portion of the second stem on the other side and a first end portion of the third stem on one side, and a second end portion of the third stem on the other side is connected to a second end portion of the first stem on the other side in another one of the corrugated units adjacent to each corrugated unit in the direction about the axis,
• the second top portion of each corrugated unit is formed to protrude only toward a distal side in a direction of insertion of the stent into the catheter, and
• a first end portion of each connection element on one side is connected to the first top portion of one of adjacent ones of the corrugated units in the axial direction, and a second end portion of each connection element is connected to the second end portion of the first stem of the other one of the adjacent ones of the corrugated units in the axial direction.
