ABSTRACT:
A guidewire includes a shaft portion and a tip portion with the tip portion having a plastic tubular coating thereover. The shaft portion of the guidewire has a given diameter and the tip portion has a diameter which decreases towards a distal end thereof. A tubular plastic coating is placed on at least the tip portion of the guidewire. The outer diameter of the coating on the tip portion exceeds the diameter of the shaft portion. The diameter of the plastic coating is reduced so as to be no greater than the diameter of the shaft portion. A hydrophilic coating may be applied over the shaft and the tip portion of the guidewire.
