  • Embolus member capturing device and embolus member capturing device leaving implement
    Publication number: 20050149111
    Abstract: An embolus member capturing device is a tubular body having one end portion and the other end portion and having a substantially constant first outside diameter, and is expandable when a radially dilating force is exerted from the inside of the tubular body. The other end portion of the embolus member capturing device is expandable to a second outside diameter greater than the first outside diameter when a radially dilating force is exerted from the inside of the tubular body, whereas the one end portion is slightly expanded from the first outside diameter or substantially maintains the first outside diameter, and either the one end portion or an intermediate portion between the one end portion and the other end portion forms an embolus member capturing portion.
