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.
Fil-guide convenant spécialement à l'introduction percutanée d'un cathéter de dilatation à ballonnet dans un vaisseau sanguin. Le fil en question est composé d'une tige souple ayant une portion proximale et une portion distale. Un assemblage de bobines hélicoïdales souples entoure la portion distale de la tige. L'assemblage de bobines hélicoïdales possède une bobine hélicoïdale distale visible à la radiographie et une bobine hélicoïdale proximale invisible à la radiographie. Les bobines hélicoïdales proximale et distale sont rattachées l'une à l'autre par une bobine hélicoïdale de raccord vissée dans la bobine hélicoïdale proximale à une extrémité, et dans la bobine hélicoïdale distale à l'autre extrémité.
