Abstract:
1. A guide wire comprising: a core comprised of a proximal end part and a distal end part; a distal covering layer contacting and circumferentially surrounding the distal end part of the core, the distal covering layer possessing a distal end and a proximal end; a proximal covering layer circumferentially surrounding the proximal end part of the core; the proximal covering layer comprising a first layer and a second layer, the first layer possessing an outer surface and extending longitudinally over a longitudinal extent; the first layer contacting and circumferentially surrounding an outer surface of the core, the second layer contacting and circumferentially surrounding an outer surface of a first part of the first layer, the second layer contacting and circumferentially surrounding less than an entirety of the longitudinal extent of the outer surface of the first layer so that a distal end portion of the first layer extends in the distal direction beyond a distal end of the second layer, an outer surface of the distal end portion of the first layer being not covered by the second layer; the distal covering layer possessing a proximal end portion, the proximal end portion of the distal covering layer contacting and covering at least a part of an outer surface of the distal end portion of the first layer; and wherein the second layer is formed from a first resin, the first layer is formed from a material containing a thermosetting resin and the first resin, and a content rate of the first resin in the second layer is higher than a content rate of the first resin the first layer, whereby the first layer exhibits stronger adhesive characteristics than the second layer relative to material forming the core and exhibits stronger adhesive characteristics than the core relative to material forming the second layer.
