ABSTRACT:
A flexible guide wire for use in the placement of a surgical instrument or the like within a human or animal body includes an elongated shaft with a coil spring mounted on its distal end, the shaft being tapered at its distal end to enhance its flexibility, and the shaft having a stepped down portion near its distal end defining a reduced diameter portion for the shaft which is less than the inner diameter of the coil spring to facilitate attachment of the coil spring thereto while providing a smooth transition between the shaft and the coil spring at their junction point.
