Abstract: A nerve stimulation electrode implantation system includes: an introduction portion that has a cylindrical main body which has an internal cavity, and an incision component which has a blunt dissection portion that bluntly dissects biological tissue, and which is formed so as to be transparent, and which is attached to a distal end portion of the main body; an observation portion that is inserted into the introduction portion such that it is able to observe the periphery of the incision component through the incision component; and a peeling portion that is positioned such that it is able to rotate around its own axis and is able to move relatively in this axial direction relative to the introduction portion, and that removes peripheral tissue from the periphery of the nerve tissue.

Abstract: To provide a medical device and a method both of which can suitably embolize a bronchus in a target part by embolizing the bronchus with (at least a part of) a living tissue during surgical treatment of lung emphysema. For example, an injection material is injected into a submucosa by the use of a syringe, and in the injected part, a swelling swollen into the internal cavity of the bronchus is formed to tightly seal the living tissue of the bronchus or a bronchiole, thereby embolizing a target bronchus.

Abstract: The present invention provides an examination apparatus which includes a base; a stage on which a specimen is mounted, the stage being movable relative to the base; and a movable image acquisition apparatus for acquiring an image of the specimen, the movable image acquisition apparatus being fixed on the stage.

Abstract: To provide a medical embolization element for embolizing the internal cavity of a tubular organ of a subject, for example, a medical embolization element for embolizing a bronchus during treatment of lung emphysema. A placing object being placed in a bifurcation of the tubular cavity includes a first embolization portion capable of airtightly sealing a first branch tubular cavity of the bifurcation, a second embolization portion capable of embolizing another second branch tubular cavity of the bifurcation, and a locking portion being locked to an edge portion of the junction portion between the first and second branch tubular cavities. Other than the above described placing object, a placing object having a balloon, a placing object shaped like cap to be attached on the tip of an endoscope, a placing object expandable in the tubular organ, and a placing object solidifies in the tubular organ are disclosed.
