    摘要： A guide wire for guiding a medical device within a patient is disclosed. The guide wire has a solid inner core made of high modulus material such as Conichrome® or a rhenium alloy, and an outer shell made of a flexible, kink resistant material such as a nickel-titanium alloy. Preferably, the modulus of elasticity of the inner core material is at least about 20 percent greater than that of the outer shell material. The outer shell is mechanically joined to the inner core through a drawing or cladding process. In various embodiments, the distal end of the guide wire can be tapered by grinding away the outer shell to expose the inner core. Because of its stiffness, it can be manually shaped by the physician or cardiologist.

    摘要： The present invention is directed to an intracorporeal device, preferably a guidewire, and method for making the device. The guidewire of the present invention is formed, at least in part, of a composite elongate core formed, at least in part, of precipitation hardened material. The elongate core members of the present invention will have an ultimate tensile strength and modulus of elasticity greater than the same for an identically dimensioned elongate member formed from superelastic NITINOL alone.

    摘要： 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.
