Abstract: The invention is directed to a guidewire having a distal section with multiple distally tapered core segments with at least two contiguous distally tapering core segments in which the most distal tapered core segment preferably has a greater degree of taper than the proximally contiguous tapered core segment. The invention is also directed to an elongated intracorporeal device, preferably a guidewire or section thereof, that has a core member or the like with a plurality of contiguous tapered segments having taper angles that are configured to produce a linear change in stiffness over a longitudinal section of the device. The device may also have a core section with a continuously changing taper angle to produce a curvilinear profile that preferably is configured to produce a linear change in stiffness of the core over a longitudinal section of the device.

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.
