A hand held vibrating device which imparts a combination of transverse and longitudinal vibrations to a guide wire, to assist in advancing the guide wire through a blood vessel and through a stenosis in a blood vessel. The vibrating device contains a motor which drives a set of gears, rotating an eccentric pin. The rotation of the eccentric pin is translated to pivoting of an oscillating arm by the essentially longitudinal movement of a connector bar. The oscillating arm is attached to the guide wire by a releasable collet. Pivoting of the collet by the oscillating arm results in the introduction of a combination of transverse and longitudinal motion to the guide wire.

Apparatus for advancing a guide wire

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.

Method for advancing a guide wire

A hand held vibrating device for vibrating a guide wire used in angioplasty and atherectomy procedures. The vibrating device permits the guide wire to be more easily passed through a stenotic segment of a blood vessel. The vibrating device includes a case, an electric motor mounted within the case, and a clamp member coupled to the electric motor for releasably securing and vibrating the guide wire. In use, the guide wire is threaded through a blood vessel to the site of a stenosis. The guide wire can then be clamped to the vibrating device, which is selectively actuated and manipulated to vibrate and push the guide wire through the stenosis.
