Abstract
A method of manufacturing a guidewire having a discrete length. The method includes the steps of feeding a first end of a corewire into an extrusion device, gripping the first end of the corewire with a gripping apparatus, and extruding a first extrusion material onto an outer surface of the corewire while the gripping apparatus pulls the corewire through the extrusion device to form an extrusion jacket on the outer surface of the corewire. The corewire has a predetermined length corresponding to a length of the guidewire.

1-34. (canceled)
A discrete length corewire to be used in manufacturing a guidewire, comprising:
- a first end section of a substantially constant first end section diameter;
- a tip section having a diameter less than the first end section diameter;
- and
- a second end section of a substantially constant second end section diameter, the second end section diameter being greater than the diameter of the tip section.
37-49. (canceled)
A discrete length corewire to be used in manufacturing a guidewire, comprising:
- a main shaft section of a substantially constant diameter;
- a tip section having a substantially constant diameter less than the diameter of the main shaft section;
- and
- a tapered section between the main shaft section and the tip section, a first end of the tapered section having a diameter equal to the diameter of the main shaft section, a second end of the tapered section having a diameter equal to the diameter of the tip section.
