  • Publication number: 20220184354
    Abstract: 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.

  • Patent number: 10856873
    Abstract: A medical apparatus for joining body lumens in a living body includes a puncture member having a lumen, a distal opening portion and a needle tip at the distal end of the lumen. The needle tip can puncture a tube wall of the body lumen to form a puncture site. The medical apparatus includes a tubular member in the lumen of the puncture member that expands radially outward and contracts radially inward and a plunger movable relative to the puncture member to release the tubular member from the distal opening portion of the puncture member. The tubular member expands to be fixed to the puncture site when the tubular member is released from the distal opening portion of the puncture member.
