Abstract
A device for delivering radiation to at least one preselected site in a vascular system of a patient, includes an elongated flexible catheter tube of a diameter for insertion into the patient's vascular system, and a flexible guide wire within the catheter tube and movable along its length. The guide wire includes a proximal end to be located externally of the patient's vascular system for moving the guide wire within the catheter tube, and a rounded distal tip at the opposite end to facilitate movement of the guide wire through the catheter tube. At least one radiation-producing element is fixed to the guide wire at an intermediate location spaced from the rounded distal tip.
