Abstract
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.
