Publication number: 20220184354Abstract: A treatment device and a treatment method are capable of improving permeability of a physiologically active substance into a blood vessel wall while maintaining a blood flow. A treatment device for treating a lesion in a blood vessel includes: a shaft portion including at least one lumen; a balloon disposed at a distal side of the shaft portion and configured to inflate; and at least one anchor member that can be inserted into the lumen and to radially expand at a state in which a distal portion protrudes from the lumen. The balloon has an outer diameter when inflated that is smaller than an outer diameter of the anchor member when radially expanded. When the anchor member radially expands in a blood vessel to come into contact with a blood vessel wall, the balloon is held away from the blood vessel wall.Type: ApplicationFiled: March 3, 2022Publication date: June 16, 2022Inventor: NAOKI ISHII
