Abstract: The disclosure provides a stent including: an annular first strut forming a wave shape; an annular second strut that is adjacent to the first strut in the axial direction and forms a wave shape; a first extension portion that is formed on a first crest as some of plural crests protruding toward the second strut in the first strut and extends from both sides with respect to a bisector of the first crest toward the second strut; a second extension portion that is formed on a second crest, which is located to be shifted in a circumferential direction with respect to the first crest among plural crests protruding toward the first strut side in the second strut, and extends from both sides with respect to a bisector of the second crest toward the first strut; and a bridge portion bridged between the first extension portion and the second extension portion.

Abstract: This embolic material is produced by a production method including a step for dispersing a mixture that contains a biodegradable polymer, an oil-based contrast agent, and a solvent in a hydrophilic liquid. The biodegradable polymer has a hydrophobic biodegradable polymer.

Abstract: An embolic material contains at least one type of polymer and a liposoluble contrast medium. A method for producing an embolic material includes extruding a raw material that is in a molten state into a solvent, and cooling the raw material so as to solidify the raw material. The raw material contains a polymer and a liposoluble contrast medium.
