摘要： The present invention relates to a drug releasing membrane for stent and a drug releasing stent for intraluminal expansion comprising the same. The drug releasing membrane according to the present invention has a two layer structure consisting of an inner layer M l and an outer layer M2, the inner layer M is a thermosetting resin layer, and said outer layer M2 is a thermoplastic resin layer containing drug particles. In addition, the drug releasing stent for intraluminal expansion according to the present invention has a structure in which said drug releasing membrane M is inserted in a cylindrical stent body S woven with shape memory alloy wire. The present invention has excellent physical properties in spi te of contact with bile during use, and is also excellent in drug therapeutic effect since drug is released only in one direction toward the skin.

摘要： The present invention relates to a stent for intraluminal expansion. The stent for intraluminal expansion comprises an inner stent A, an outer stent B and fixing threads C for fixing these stents as one unit. The outer stent B is inserted over the inner stent A in such a way that the space portions of the inner stent A and the space portions of the outer stent B are alternated with each other, so the outer surface of the inner stent and the inner surface of the outer stent are in close contact with each other, and both ends of the outer stent and inner stent are fixed as one unit by fixing threads C. According to the stent for intraluminal expansion of the present invention, in which form recoverability of each of the inner stent A and the outer stent B is excellent, expansion is easy after it is inserted into the lumen body because the cylindrical film membrane is not fixed by fixing thread C, and the space portions Id of the inner and outer stents are overlapped alternately with each other so that it is possible to effectively prevent cancer cells, etc. from penetrating into the lumen.
摘要翻译：本发明涉及一种用于管腔内扩张的支架。用于管腔内扩张的支架包括内支架A，外支架B和用于将这些支架固定为一个单元的固定线C. 外支架B以内支架A的空间部和外支架B的空间部彼此交替的方式插入内支架A上，内支架的外表面和内支架外支架的表面彼此紧密接触，并且外支架和内支架的两端通过固定螺纹C固定为一个单元。根据本发明的用于管腔内扩张的支架，其中形状可恢复性内支架A和外支架B各自优异，因为圆柱形膜膜不通过固定螺纹C固定，因此内插体和外支架的空间部分Id之间容易扩张，因此，交替地重叠，使得可以有效地防止癌细胞等渗透到内腔中。
