    Abstract: Provided are an administrable aqueous solution to a living body and a method for manufacturing the same, the administrable aqueous solution having a function of supplying sufficient oxygen to peripheral cells, causing less damage and injury of cells under a hypoxic or anaerobic stimulation, and continuously exhibiting a sufficiently high and stable effect to protect cells. The administrable aqueous solution to a living body according to the present invention contains oxygen nanobubbles having a mean particle size of 30 nm or less and a density of 1016 bubbles per ml, preferably a mean particle size of 1 to 10 nm and a density 1017 bubbles or more per ml, respectively, as determined by a measurement with a cryo-transmission electron microscope by an ice-embedding method. The administrable aqueous solution to a living body according to the present invention contains oxygen nanobubbles which are generated by jetting an aqueous solution containing dissolved oxygen from the outside of a cylinder, the cylinder being provided with 2 or more small through holes formed in the circumferential direction, via the small through-holes under atmospheric pressure or higher and thus bringing the jetted solution into collision in such a manner that water hammer is concentrated at the center of the cylinder on the same plane parallel to a cross-section in a radial direction of the cylinder.

    Abstract: A filler delivery device is configured to place a filler inside a bulge occurring in a body lumen. The filler delivery device includes a frame member configured to be expandable and compressible, and a tubular member through which a catheter for injecting the filler into the bulge is insertable. The tubular member is provided such that, when the frame member is in an expanded state, an open end of the tubular member is directed in a direction intersecting an extending direction of the body lumen. The filler material includes a base gel having flowability with which the filler material flows inside the catheter, and shape retainability with which the filler material stays inside the bulge after being injected from the catheter into the bulge, and a solidification promoting substance that promotes solidification of blood inside the bulge.

    Abstract: A capturing unit provided on a distal end of a second tube can be deformed into a contracted state and an expanded state, in which the capturing unit is deployed to form a capturing chamber. The capturing chamber has an opening area decreased as it goes from a distal end opening of the capturing chamber toward a proximal end opening of the capturing chamber. A third tube rotatable relative to the second tube and a cutting unit provided on a distal end of the third tube for cutting a foreign substance are arranged in a second lumen. In the expanded state of the capturing unit, the cutting unit is arranged more toward the proximal end opening of the capturing chamber than the distal end opening.
