A method and an angioplasty balloon catheter used in a method of preventing or minimizing incidence of neointimal hyperplasia (NIH) in a blood vessel of an animal following angioplasty treatment. The method comprising locating the angioplasty balloon catheter at a vessel site where angioplasty treatment is desired, wherein a balloon component of the catheter is at least partially coated on an external surface thereof with a photo-labile drug / linker conjugate of Formula I; wherein the balloon is inflated at the site to initiate release of the drug / linker conjugate to vessel wall at the site and an optical fiber light diffuser, connected by optical fiber to a source of UV light at a wavelength of from about 350 nm to about 380 nm, is located within the balloon to emit said UV light, wherein UV light emission is of suitable power and for sufficient duration to cleave the drug / linker conjugate and activate an effective amount of the drug of Formula II to prevent or minimize NIH following the angioplasty treatment at the site.
本发明涉及一种方法和一种用于预防或最小化在动物的血管内进行成形术治疗后发生新内膜增生(NIH)的血管成形术球囊导管。该方法包括将血管成形术球囊导管定位在需要进行血管成形术治疗的血管部位,其中导管的球囊组件至少部分地涂覆有配方I的光敏药物/连接剂共轭物的外表面;在该部位充气球囊以启动在该部位向血管壁释放药物/连接剂共轭物,并且在球囊内放置光纤光扩散器,通过光纤连接到波长为约350nm至约380nm的紫外线光源,其中紫外线光发射具有足够的功率和足够长的持续时间,以断裂药物/连接剂共轭物并激活配方II的有效量,以预防或最小化在该部位进行血管成形术治疗后的NIH。
