Abstract
In accordance with the present invention, there is provided a guidewire for navigating through body vessels so as to deliver a balloon catheter or the like. The guidewire has an elongated core wire having distal and proximal ends and a longitudinal axis extending therebetween. The guidewire also has a coiled spring surrounding the distal end of the core wire. Lastly, the guidewire includes a tube surrounding the core wire proximal to the coiled spring. The tube is able to slide back and forth with respect to the longitudinal axis of the core wire. The tube has a distal end and a proximal end. The distal end of the tube is coupled the proximal end of the coil so that as the tube slides along the longitudinal axis of the core wire, the length of the coiled spring changes, thereby changing the flexibility of the coil.
