PROBLEM TO BE SOLVED: To provide an embolization therapy device in which the adhesion between an embolic agent ejected and a device is prevented or suppressed by a simple structure.SOLUTION: An embolization therapy device 10 includes a long body 12 having first and second lumens 20, 24 inserted into a blood vessel and enabling an embolic agent X to flow therein. The long body 12 includes: multiple branch tubes 32 having outlets 48 for ejecting the embolic agent; an expansion and contraction unit 29 for expanding and contracting based on a flow operation of the embolic agent in the base end position rather than the multiple branch tubes 32; and an outside catheter 16 for receiving the multiple branch tubes 32. The multiple branch tubes 32 are spaced apart to each other with exposure from the outside catheter 16, and shaped so as to expand radially outward. |
