Abstract

A guidewire having a flexible coil with a tapered distal tip. Preferably, the flexible coil has a polymer coating at least at its tapered distal portion. The polymer coating may comprise polyurethanes or other suitable polymers. The guidewires of the invention provide desirable performance characteristics, particularly when used to cross relatively tight lesions such as chronic total occlusions.
