The invention is drawn to a guidewire comprising proximal, medial and distal segments and an S-shape portion. The S-shape in the guidewire allows for the guidewire to advance around sharp comers in the body. The curved S-shaped portion of the guidewire can act as a spring and absorb part of the pushing force of the guidewire as well as help redirect the end tip of the guidewire. This design allows for the curves of guidewire to push off the back side of a vessel and allow the end tip of the guidewire to enter into a side branch vessel with greater ease. |
