a primary clamp housing;
an electromagnet secured within the primary clamp housing;
a plunger slidingly disposed within the primary clamp housing such that the plunger can move towards the electromagnet when the electromagnet is actuated and can move away from the electromagnet when the electromagnet is not actuated;
wherein actuating the electromagnet causes the plunger to move towards the electromagnet, thereby clamping the guidewire between the electromagnet and the plunger.
