Abstract:
1. A guide wire comprising: a wire body possessing a longitudinally extending central axis that extends along an entire length of the wire body, the wire body comprising a first wire and a second wire; said first wire being disposed at a distal end of the guide wire; said second wire being joined directly to a proximal end of said first wire by way of a joint; said second wire being made of a material having an elastic constant greater than an elastic constant of a material of which said first wire is made; and said joint between said first wire and said second wire possessing a curved shape that is one of a dish shape, a spherical shape and a parabolic shape as seen in a longitudinal cross-section of the guide wire, and said joint possessing a three-dimensional configuration defined by rotation of the curved shape about the central axis, such that said joint increases torque transmission characteristics of the wire body.
