    • Wire guide devices, and methods (300) of using same, having an elongate shaft (10, 110) with a first end portion (14, 114) and a flexible second end portion (16,116) having a non-coiled portion (24, 124) comprising a nominal outer circumference (22, 122) disposed about a longitudinal axis (18, 118) and having a first outer surface (12, 112) including the nominal outer circumference( 22, 122) and defining a first surface area (30, 130). Textures such as protuberances (26), indentations (28), peaks (160), and/or valleys (161) are disposed substantially circumferentially about the nominal outer circumference (22, 122) and defining an effective perimeter (21, 121) greater than the nominal outer circumference (22, 122) and having a second outer surface (20, 120) defining a second surface area (40, 140) greater than the first surface area (30, 130). Hydrophilic materials and therapeutic agents may be disposed partially on the second end portion (24, 124) and a coating (54, 74), and a membrane 84 may be disposed about non-coiled portion (24, 124) and coating (54, 74) to form reservoirs (73) or lumens (76) for delivering hydrophilic materials and delivering therapeutic agents.
    • 线引导装置和使用该导向装置的方法(300)具有带有第一端部(14,114)的细长轴(10,110)和具有非卷绕部分(24)的柔性第二端部(16,116) 124),包括围绕纵向轴线(18,118)设置的标称外圆周(22,122),并且具有包括标称外圆周(22,122)的第一外表面(12,112)并限定第一表面区域 30,130)。 基本上围绕公称外圆周(22,122)周向地设置诸如突起(26),凹陷(28),峰(160)和/或谷(161)的纹理,并且限定更大的有效周长(21,121) (22,122),并且具有限定大于第一表面区域(30,130)的第二表面区域(40,140)的第二外表面(20,120)。 亲水性材料和治疗剂可以部分地设置在第二端部(24,124)和涂层(54,74)上,并且膜84可以设置在非卷绕部分(24,124)周围, 74)以形成用于递送亲水材料并递送治疗剂的储存器(73)或腔(76)。
