Abstract
The guide wire of this invention is especially suited for the percutaneous introduction of a balloon dilatation catheter into a blood vessel. It contains a flexible shaft with a proximal portion and a distal portion. A flexible helical coil assembly surrounds the distal portion of the shaft. The helical coil assembly has a radiographically visible distal helical coil and a proximal radiographically invisible helical coil. The proximal helical coil and the distal helical coil are attached to each other by a connecting helical coil that on one end is screwed into the proximal helical coil and on the other end is screwed into the distal helical coil.
