Wire guides having novel outer surface areas and reservoirs for enhancing hydrophilic properties and delivering therapeutic agents

It has the 1st end portion (14, 114) and the non-coil volume portion (24, 124) equipped with the nominal perimeter enclosure (22, 122) arranged around the direction axis of Nagate (18, 118), The existing flexible 2nd end portion (16, 116) which has the 1st outside surface (12, 122) which has demarcated the 1st surface area (30, 130) while including the nominal perimeter enclosure (22, 122), preparation ている -- the method (300) of using the wire guide equipment which has a long and slender shaft (10, 110), and the equipment is offered. A projection (26) -- it becomes depressed and the grain of (28), a mountain (160), a valley (161), etc. , It is substantially arranged in the direction of a circumference around the nominal perimeter enclosure (22, 122), It has the 2nd outside surface (20, 120) which demarcates larger effective peripheral length (21, 121) than a nominal perimeter enclosure (22, 122), and demarcates the 2nd larger surface area (40, 140) than the 1st surface area (30, 130). A hydrophilic material and a curative medicine are partially arranged on the 2nd end portion (24, 124) and covering (54, 74), The film 84 is arranged around a non-coil volume portion (24, 124) and covering (54, 74), and can form the storage part (73) or 管腔 (76) for sending out of a hydrophilic material and a curative medicine.
