    • The invention provides a method of treating vulnerable plaque at a site in a vessel. A vulnerable plaque site is identified for treatment. A radiation source is introduced into a vessel containing a vulnerable plaque site identified for treatment. The radiation source is guided to a position adjacent to the treatment site. A therapeutically effective dose of radiation is delivered to the vulnerable plaque site. As the radiation impinges upon the wall of the lumen, it promotes cell growth. Such growth can serve to strengthen the thin fibrous cap found atop a vulnerable plaque lesion. With the lesion thus stabilized, time is provided for the use of statin drugs or other agents to shrink or remove the lipid pool beneath the cap.
    • 本发明提供了一种在容器中的部位处理易损斑块的方法。 确定易受伤害的斑块部位进行治疗。 将辐射源引入含有鉴定用于治疗的易损斑块部位的容器中。 将辐射源引导到与治疗部位相邻的位置。 治疗有效的辐射剂量被递送到易损斑块部位。 当辐射照射在管腔的壁上时,它促进细胞生长。 这种生长可以用于加强在脆弱斑块病变上面发现的薄纤维帽。 随着病变如此稳定,提供了使用他汀类药物或其他药物收缩或去除帽下方的脂质池的时间。

    • The stent with an intermittent coating of the present invention provides a coating having a plurality of discrete coating sections disposed on a stent, i.e., an intermittent coating. The individual coating sections can contain different drugs or therapeutic agents, can be made of different polymers, can be made with different solvents, or combinations thereof. The coating sections can be applied in patterns such as ring patterns, striped patterns, spotted patterns, or dot matrix patterns. In one embodiment, the regions can be large relative to the stent, such as a ring pattern including one therapeutic agent in the radial regions at the ends of a stent and a different therapeutic agent in the radial region in the middle. In another embodiment, the regions can be small relative to the stent, such as a dot matrix pattern with each grid region being a small point.
    • 具有本发明的间歇涂层的支架提供了具有设置在支架上的多个离散涂层部分的涂层,即间歇涂层。 各个涂层部分可以含有不同的药物或治疗剂,可以由不同的聚合物制成,可以用不同的溶剂或其组合制成。 涂层部分可以以诸如环形图案,条纹图案,斑点图案或点阵图案的图案来应用。 在一个实施方案中,相对于支架的区域可以较大,例如在支架端部的径向区域中包括一种治疗剂的环形图案,以及在中间的径向区域中的不同的治疗剂。 在另一个实施例中,相对于支架的区域可以较小,例如每个格栅区域是小点的点阵图案。
