1. An atherectomy system, comprising:
an atherectomy burr;
a drive mechanism adapted to rotatably actuate the atherectomy burr, the drive mechanism adapted to accommodate a guidewire extending therethrough;
a controller adapted to regulate operation of the drive mechanism;
a guidewire extending through the drive mechanism; and
an electromagnetic guidewire clamp adapted to releasably secure the guidewire relative to the drive mechanism, the electromagnetic guidewire clamp comprising:
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.
