<p>Disclosed is a guidewire particularly suited for use in rotational atherectomy. The guidewire has increased lateral flexibility in the distal region, and a substantially constant diameter throughout. The exterior diameter at any point is substantially equal to the sum of the diameter of the central core wire, and twice the diameter of the wire of the spring coil, if any, mounted thereon. At proximal portions of the guidewire, the outer spring coil may be deleted.</p> |
