ABSTRACT:
A guidewire for placement within a blood vessel for penetrating an occlusion therein. The guidewire comprises a length of flexible wire having a lumen extending therethrough. The distal end of the guidewire is generally arcuate and has a diameter greater than that of the wire immediately proximal thereto. A flexible stylet substantially the same length as the flexible wire may be disposed within the lumen of the wire. In operation, the arcuate distal end of the guidewire is positioned in the blood vessel against an occlusion, and a dottering action is thereafter provided whereby the arcuate distal end of the guidewire repeatedly impinges on the occlusion until penetration of the occlusion occurs.
