A guidewire insertion device, comprising:
- a guidewire including a ferromagnetic element disposed on or in a tip of the guidewire and an electromagnet disposed on or in the tip of the guidewire;
- and
- a controller configured to modulate electric power applied to the electromagnet to produce reciprocating movement of the tip of the guidewire driven by magnetic interaction between the electromagnet and the ferromagnetic element;
- wherein at least the tip of the guidewire is hollow;
- and further comprising
- a nonmagnetic shaft disposed inside the hollow tip of the guidewire;
- wherein the ferromagnetic element includes first permanent magnet and a second permanent magnet disposed at opposite ends of the nonmagnetic shaft inside the hollow tip of the guidewire.
