    摘要： Disclosed is a method for treatment of emphysema by which it is possible to reduce the volume of pulmonary alveoli or alveolar sacs abnormally enlarged with destruction by emphysema. The method for treatment of emphysema includes: (a) inserting a catheter having a balloon into a bronchus or bronchiole; (b) dilating the balloon to occlude the bronchus or bronchiole; (c) shrinking pulmonary alveoli or alveolar sacs on the downstream side of the bronchus or bronchiole occluded in the step (b); and (d) injecting a hardening agent through the catheter into the respiratory region and hardening the hardening agent.

    摘要： Disclosed is a method for electroporation with which higher transformation efficiency may be attained than that attained by the conventional methods. In the method of electroporation, cells and DNAs are suspended in a buffer containing potassium ion as a cation and an amino acid ion and/or an organic acid ion as an anion, and substantially not containing chloride ion, and high voltage is applied thereacross.

    摘要： A stent capable of retarding or preventing occlusion resulting from granulation includes: an outer annular body with a circular cross section in which an outer through-hole penetrating in a direction intersecting the radial direction of the circular cross section is formed and which can expand and contract in the radial direction; and an inner annular body disposed on the inside of the outer through-hole, forms a double annular cross section together with the outer annular body at least at the openings of the outer through-hole, and in which an inner through-hole penetrating in a direction that intersects with the radial direction of said circular cross-section is formed. When placed indwelling in a living body, the outer annular body can expand in the radial direction and can thereby support the living tissue with at least the opening of the inner through-hole of the inner annular body spaced from the living tissue.

    摘要： A catheter includes an outer tube, and an inner tube which is disposed inside the outer tube and through which a guide wire is passed via a distal-side opening and a proximal-side opening. The outer tube has, in the axial direction thereof, at least: a first region on the distal side; a second region disposed on the proximal side and higher in rigidity than the first region; and a transition region which is provided between the first region and the second region and of which rigidity varies from the same rigidity as that of the first rigidity to the same rigidity as that of the second rigidity. The outer tube is configured with an opening, to which the proximal-side opening of the inner tube is connected, being provided in the second region.

    摘要： A medical device includes a tubular body having a first lumen so designed as to receive a fluid from an opening at one end of the first lumen and discharge the fluid from an opening at the other end of the first lumen, and an expandable body attached to the tubular body. The first lumen communicates with the space inside the expandable body and the expandable body expands by the internal pressure of the fluid which is injected from the opening at one end and enters the space inside the expandable body through the first lumen.
