Abstract
An angioplasty guidewire includes a proximal shaft and an intermediate section extending from the shaft to a distal joint and having a stiffener and a flexible member. The stiffener and the flexible member are disposed in coaxial slidable relationship and operable, as the stiffener and flexible member undergo relative axial shifting, to cooperatively impart a variable stiffening force on the intermediate section. A flexible distal tip mounts to the end of the intermediate section and projects axially therefrom.
