Patent Images
1. A method for making a guidewire comprising:
- removing material from a distal portion of a core wire to define a distal tip extending from a proximal portion of the core wire, the distal tip having a maximum cross-sectional dimension not exceeding a maximum diameter of the proximal portion;
removing material from a distal section of the proximal portion of the core wire to define a recessed portion; and
positioning a collar adjacent to the distal tip about the proximal portion including advancing the distal tip through a lumen of the collar and placing the collar about the recessed portion.
