    • Methods and apparatus are disclosed for customizing an elution profile of a stent after manufacture of the stent has been completed. The stent includes a plurality of side ports for eluting a drug formulation within a lumenal space of a hollow strut that forms the stent. An effective diameter of at least one side port of the plurality of side ports of the stent is modified in order to customize an elution profile of the stent. In an embodiment hereof, the plurality of side ports are completely blocked or plugged with a filler material during the manufacture of the stent and at least a portion of the filler material is removed to increase an effective diameter of at least one side port of the plurality of side ports of the stent in order to customize an elution profile of the stent. In another embodiment hereof, the plurality of side ports are open following the manufacture of the stent and at least one side port of the plurality of side ports of the stent is at least partially filled with a filler material to decrease the effective diameter of the at least one side port in order to customize an elution profile of the stent. In another embodiment hereof, the stent is soaked within a liquid to remove at least a portion of the drug formulation from the lumenal space of the hollow strut to thereby customize an elution profile of the stent.
    • 公开了用于在支架制造完成后定制支架的洗脱轮廓的方法和设备。 该支架包括多个侧孔,用于在形成支架的中空支柱的内腔空间内洗脱药物制剂。 对支架的多个侧孔中的至少一个侧孔的有效直径进行修改以便定制支架的洗脱轮廓。 在本发明的一个实施例中,在制造支架期间,多个侧孔被填充材料完全堵塞或堵塞,并且至少一部分填充材料被去除以增加多个侧孔中的至少一个侧孔的有效直径 为了定制支架的洗脱曲线,支架侧孔的尺寸。 在本发明的另一个实施例中,在制造支架之后,多个侧端口是开放的,并且支架的多个侧端口中的至少一个侧端口至少部分地填充有填充材料,以减小支架的有效直径 至少一个侧端口以定制支架的洗脱轮廓。 在本发明的另一个实施方案中,将支架浸入液体中以从中空支撑物的腔空间去除至少一部分药物制剂,从而定制支架的洗脱轮廓。
