Abstract

A guide wire comprising a super-elastic core member which consists of a proximal section, a distal section smaller in diameter than the proximal section and a intermediate section between the proximal section and the distal section, an X-ray opaque metal coil attached to the distal section of the core member in tight contact with the distal section, a synthetic resin envelope which covers the core member and the X-ray opaque metal coil to form a substantially smooth outside surface, and a hydrophilic lubricative layer which covers the outside surface of the synthetic resin envelope. The distal section of this guide wire can be reshaped repeatedly. The X-ray visibility of the distal section is improved.
