Torsionally stabilized guide wire for use in larger vessels of the vascular system. A relatively flexible helical coil is positioned over the distal end portion of an elongated shaft which increases in flexibility toward its distal end. The coil is affixed to the shaft at the proximal and distal ends of the coil and at an intermediate point near the distal end. A jacket having an outer diameter substantially equal to the outer diameter of the coil covers the shaft between the proximal end of the shaft and the proximal end of the coil. In one disclosed embodiment, the jacket is formed by heat shrinking a tubular sleeve of polyethylene about the shaft.

In a guide wire for use in the vascular system: an elongated shaft having a relatively flexible distal end portion, a helical coil extending over the distal end portion of the shaft and a substantial portion of the shaft proximal to the relatively flexible distal end portion, said helical coil being affixed to the shaft at its ends and at a point between its ends, and a jacket of polyethylene heat shrunk about the shaft proximally of the helical coil and having a thickness corresponding to the thickness of the wire which forms the coil and an outer diameter substantially equal to the outer diameter of the coil.
