ABSTRACT:
The invention provides a handle for a rotational atherectomy device, the handle including a guide wire clamp and a turbine brake operatively interconnected with the guide wire clamp so that the brake automatically prevents rotation of the turbine when the guide wire is unclamped. The brake is movable from a brake-released position to a brake-engaged position, in which position the brake prevents rotation of the turbine. A manual override is also provided, permitting unclamping of the guide wire independent of the position of the brake.
