Abstract
A shaft suppresses a rise in operation resistance as it is pushed and pulled even inside an extremely winding blood vessel and thus secures sufficient torque transmission characteristics and operability. A guidewire may employ the above-described shaft. The shaft is twisted along its longitudinal axis and has a cross section that forms a substantially rectangular shape in a direction perpendicular to the longitudinal axis. Moreover, the cross section of the shaft has a projection that projects arcuately.
