Abstract
A guidewire which has a tubular member, a flexible distal tip secured to the distal end of the tubular member and an exchangeable elongated core member disposed within the lumen of the tubular member. The elongated core member can be advanced distally to the distal end of the tubular member or withdrawn proximally out of the tubular member proximal end. While the guidewire is inside a patient's vessel, the elongated core member can be removed from the tubular member and exchanged for a different elongated support. By exchanging the elongated core member, the physician is able to change guidewire characteristics, such as flexibility or shape, to facilitate movement of the guidewire within the patient's lumen.
