Abstract: A stent with at least one severable supporting device and methods of coating using the same are disclosed. The severable supporting device can be an end tube or a tab attached to some portion of the stent by at least one “gate” or attachment. The end tube or tab may be part of the design of the stent when it is originally manufactured, or it may be attached to the stent in a secondary process by a biocompatible glue or solder. The end tube or tab can be used to support a stent during a coating process eliminating the need for a mandrel which would otherwise contact the stent during the coating process.

Abstract translation: 公开了具有至少一个可分割支撑装置的支架和使用其的涂覆方法。 可分开的支撑装置可以是通过至少一个“门”或附件附接到支架的一些部分的端管或突出部。 当最初制造时，端管或突片可以是支架的设计的一部分，或者可以通过生物相容的胶或焊料在二次过程中附接到支架。 终端管或接头可用于在涂覆过程中支撑支架，从而消除了在涂覆过程期间将接触支架的心轴的需要。
