Abstract
An intraluminal guidewire for use in medical procedures in general, and cardiovascular procedures in particular. A core wire is formed as the inner member of the guidewire. A distal helical coil is fixedly attached to the distal end of the core wire. A proximal helical coil is fixedly attached to the core wire proximally of the distal coil. The proximal end of the distal coil and the distal end of the proximal coil can be fixedly mounted in spaced relation on a flexible spacer sleeve. The two coils can be of different materials, such as stainless steel and gold, having significantly differing degrees of radiopacity. The sleeve can be a third degree of radiopacity, preferably selected to show a dark spot on a fluoroscope. The coils can be attached to the core wire by a flexible adhesive.
