Drug-coated balloons (DCB) have been developed in recent years to overcome some of the drug-eluting stents limitations. There is an established indication for the use of DCB in the treatment of in-stent restenosis and they are also variably used in various setting, in particular small coronary vessels and bifurcations. Until 2016, all DCBs available in Europe eluted paclitaxel, a highly lipophilic drug with narrow therapeutic window. In April 2016 a new sirolimus-coated balloon (Magic Touch®, Envision Scientific PVT, Bhatpore, India) obtained the CE Mark. This device shares a new-generation delivery system and is able to release in a few seconds an effective dosage of sirolimus.
近年来,药物涂层球囊(DCB)得以研发,以克服一些药物洗脱支架的局限性。DCB在治疗支架内再狭窄方面已有既定的适应症,并且它们也在各种情况下被不同程度地使用,特别是在小冠状动脉血管和分叉病变中。直到2016年,欧洲所有可用的DCB都洗脱紫杉醇,这是一种具有窄治疗窗的高度亲脂性药物。2016年4月,一种新型西罗莫司涂层球囊(Magic Touch®,Envision Scientific PVT,印度巴特波尔)获得了CE标志。该装置采用了新一代输送系统,能够在几秒钟内释放有效剂量的西罗莫司。
