<p>A guide wire (20) is provided with a root section to which a rotation mechanism is connected, a body section (24) inserted in an axial through-hole in a catheter (10) and adapted to be able to move axially and to rotate circumferentially, a tip section (28) which is formed by axially dividing a portion of an end of the body section (24), said portion having a predetermined axial length, into elongated portions by slits. The guide wire (20) consists of a super elastic shape memory alloy material. When the tip section (28) is caused to project from the tip of the catheter (10), the elongated divided portions are expanded in the direction perpendicular to the axis direction to become an expanded tip section (30) forming a predetermined envelope outline shape.</p> |
