GUIDEWIRE HAVING BONDED PROXIMAL AND DISTAL SEGMENTS

Abstract:

A guidewire having a proximal core wire formed from a first metal alloy is connected to a distal core wire formed from a second metal alloy. A tubular member is sized to receive an end of the proximal core wire and an end of the distal core wire in a butting configuration. The tubular member is attached to the proximal core wire and the distal core wire to form a joint connecting the two wires together.
