Abstract
An apparatus for use as a catheter guidewire and a method for making a catheter guidewire. The apparatus comprises an elongate non-coiled wire having a proximal portion, a distal tip and a flexible portion located between the proximal portion and the distal tip having axially spaced grooves cut therein. The method for making the guidewire includes burnishing one end of a wire to create a rounded distal tip and cutting a predetermined pattern of axially spaced grooves in a length of wire adjacent to the distal tip to create a flexible portion.
