Abstract
The present invention includes a medical guidewire having improved torque transfer from the proximal end of the guidewire to its distal end. The guidewire comprises a radiopaque coil affixed about its distal end and a flexible polymer cladding over the distal end of the wire, wherein the coil comprises a plurality of spirals having gaps therebetween such that the cladding fills the gaps between the spirals and adheres to the wire. The flexible cladding is colored to assist operators in quickly differentiating the distal end of the wire from its proximal end and the color of the cladding is selected from a predetermined color scheme to indicate the particular size of the guidewire. A method for forming a curved distal tip comprises the steps of urging a blade against a first surface of the wire, urging an opposing force against an opposing second surface of the wire immediately opposite the blade, and pulling the wire over the blade such that the first surface is stressed by the blade, thereby causing the wire to curve towards the stressed area.
