Abstract
A method of using a hand held vibrating device for transversely vibrating a guide wire in performing angioplasty and atherectomy procedures. The sinusoidal vibrations introduced into the wire by the vibrating device permit the guide wire to be more easily passed through a blood vessel or a stenotic segment of a blood vessel. The guide wire is threaded through a blood vessel until resistance is met. The guide wire can then be clamped to the vibrating device, which is selectively actuated and manipulated to sinusoidally vibrate the wire, overcoming the resistance, and facilitating the further advancement of the guide wire.
