Abstract
A guidewire is provided for use with medical devices such as catheters. The guidewire has a structure which is particularly suitable for use as a micro-guidewire which is small enough for use even within the cerebral vascular system. The guidewire includes a unitary core wire of nickel and titanium alloy, which unitary core wire has a distal tip portion including a ribbon tip. A coil is positioned generally along the outside surface of the distal tip portion, including the ribbon tip. The distal tip portion of the device exhibits super-elasticity properties by which the tip is easily bent and rebent without kinking.
