Abstract
An atherectomy device having a handle housing, a rotatable prime mover movable longitudinally with respect to the handle housing, a rotatable drive shaft having a proximal end connected to the prime mover for rotation and longitudinal movement therewith, and a distal end portion having a tissue removal implement usable to remove tissue from a bodily passageway. A guide wire clamp is disposed within the handle housing for releasably clamping the proximal portion of a guide wire. An override clamp is removably securable to the handle housing for moving the guide wire clamp to a guide wire-released position and for holding the guide wire clamp in such released position. The override clamp may also include a mechanical linkage to the prime mover so that the override clamp locks the prime mover in a particular longitudinal position with respect to the handle housing.
