Abstract
This invention is a guidewire for guiding a catheter and is used for accessing a targeted site within a lumen system in a body. The guidewire or guidewire section has a wire core, a distal tip region, a polymeric tie layer, and a lubricious coating. The tie layer is preferably constructed to provide for sections of varying flexibility along the length of the guidewire. Variations of the tie layer provide for axially spaced sections of varying flexibility, radially layers of varying flexibility of both. In a special variation, the tie layer is constructed with at least one section providing increased stiffness distally.
