Abstract
A guidewire formed from drawn filled tubing having an inner core member encased in an outer layer. The inner core member is formed from a linear elastic or superelastic material and the outer layer is formed from a metal alloy such as 35N LT. A portion of the outer layer is ground down to form a feather edged joint between the outer layer and the inner core member.

A method of forming a guidewire, comprising:
- providing an elongated tubular member having a proximal end, a distal end, an inner core member extending from the proximal end to the distal end and formed from a first material, and an outer layer formed from a second material and surrounding the inner core member;
- and
- forming a feather edged joint defining a tapered transition segment between the outer layer and the inner core member by completely removing a distal portion of the outer layer along a first constant diameter section of the inner core member.
