    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: An intravascular guide wire having two core materials joined together without the use of a connector tube or sleeve, the core materials being stainless steel and psuedoelastic metal alloy, nitinol. The core materials are joined to each other through an intermediate transition piece made essentially of nickel, which is welded on either side to the two core materials. In a multi-segment intravascular guide wire, discrete, high modulus and medium modulus core portions of different materials are welded to a shapeable, low modulus distal core portion made of a third material having a flattened, shapeable section at a most distal end that is not welded to but made from the distal core portion, so the flattened, shapeable section can be deformed to create a steerable tip. Processes such as simultaneous resistance and friction welding can be used to join the core portions.

    Abstract: A guide wire for use in a medical procedure having a shapeable tip integral with and made from the distal end of a superelastic nitinol distal section of the guide wire, wherein the shapeable tip can be finger kinked. Such a guide wire includes an elongated core made from a superelastic nitinol alloy at the distal end, the distal end of the elongated core having a tapered section leading to a shapeable distal tip. The shapeable tip is an extension of the distal end of the nitinol distal section, and includes permanent strain hardening from at least two different radial directions imparting crystallographic texture in the radial directions that eliminate superelasticity so that permanent deformation can be achieved with finger pressure.
