    • PROBLEM TO BE SOLVED: To provide an orifice device for delivering one or a plurality of drugs. SOLUTION: This orifice device for delivering one or a plurality of drugs includes an inner member having a proximal end and a distal end; and a plurality of windings helically wound around the inner member. Each winding defines a separate layer and each winding includes at least one wire helically wound around the inner member. The plurality of windings and the inner member define at least two separate channels for carrying one or a plurality of drugs therethrough. An inlet is at the proximal end of each of the plurality of windings and an outlet is at the distal end of the plurality of windings. At least one of the plurality of windings has a plurality of discrete wires helically wound in parallel around the inner member and at least one of the plurality of windings respectively. In some embodiments, at least two of the plurality of discrete wires have a different dimension. Additionally, an outer member is disposed over the plurality of windings. COPYRIGHT: (C)2006,JPO&NCIPI
    • 要解决的问题:提供一种用于递送一种或多种药物的孔装置。 解决方案:用于递送一种或多种药物的孔装置包括具有近端和远端的内部构件; 以及螺旋缠绕在内部构件上的多个绕组。 每个绕组限定单独的层,并且每个绕组包括围绕内部构件螺旋缠绕的至少一个线。 多个绕组和内部构件限定用于承载一个或多个药物的至少两个分开的通道。 入口处于多个绕组中的每一个的近端处,并且出口位于多个绕组的远端。 所述多个绕组中的至少一个绕组分别具有围绕所述内部构件和所述多个绕组中的至少一个并列地螺旋缠绕的多个离散线。 在一些实施例中,多个离散导线中的至少两个具有不同的尺寸。 此外,外部构件设置在多个绕组上。 版权所有(C)2006,JPO&NCIPI
