ABSTRACT:
A method and apparatus for producing a guide wire including a core wire surrounded by a heat shrunk polymeric plastic sleeve of variable wall thickness. The core wire is inserted into the sleeve, and heat is applied to successive axially spaced annular zones of the sleeve to heat shrink it around the core. The distal portion of the sleeve and core wire are moved relative to the heat zones at one rate of speed, and the proximal portion of the sleeve is moved relative to the heat zones at a different rates of speed. The thickness of the heat shrunk sleeve is varied by controlling the rates of speed such that a variable and controlled tension is applied to the sleeve as it is being heat shrunk.
