Variable Stiffness Guidewire Systems |
摘要 |
A variable stiffness guidewire comprises a outer body including a plurality of coil windings that are oriented in a first direction. The outer body has a proximal end and a distal end and a hollow interior therebetween. A tension element is positioned within the hollow interior and has first and second opposed ends, wherein the second end is coupled to the distal end of the outer body. The tension element includes a plurality coil windings that are oriented in a second direction opposite to the first direction. The tension element is configured to be pulled in a direction away from the distal end of the outer body to increase a stiffness in at least a portion of the guidewire.
