Abstract

A guide wire (20) for a catheter has a solid tubular portion with a flexible body fixed to its distal end (22). The distal end (22) of the body may be composed of a material more radiopaque than its proximal portion. Optical fibers (24) are disposed within the assembly and terminate in a radiopaque tip at the distal end (22) of the body. The guide wire (20) may have a longitudinal marker wire (32) for providing stiffness and radioscopic tracking characteristics. The guide wire (20) has a proximal end attached to the tube and a distal end (22) that also terminates in the tip. The invention may be maneuvered and positioned in a vascular area like a conventional guide wire. Then, laser energy from a laser light source at a proximal end of the guide wire is conveyed to the vascular area by the optical fibers (24) to ablate an obstruction. A larger catheter may then be slid over the guide wire to continue the ablation operation. Employing polyester tubing for the distal body, the guide wire may be used in peripheral angioplasty applications. Alternatively, the distal body may be implemented with a metal coil and may be used in coronary angioplasty.
