INTRALUMINAL INDWELLING OBJECT

摘要

PROBLEM TO BE SOLVED: To provide an intraluminal indwelling object by which the influence of a length change with the extension of a stent graft on positioning is evaded and the stent graft indwells at a proper position in a proper state under X-rays contrast. SOLUTION: The intraluminal indwelling object 1 is provided with a structure body 2 which is formed to be a tube shape and deformed to have a first outer diameter and the second one being larger than the first one and with keeping means 3a-3f which are extended in the axial direction of the structure body 2, by which the body 2 is kept in a second outer diameter state. Then the means 3a-3f are provided with high X-rays contrast markers which are arranged at positions to be the both end parts of the structure body 2 in a state where the means 3a-3f keep the structure body 2 in the second outer diameter state.
