    摘要： A guidewire for intraluminal advancement of a medical device within a patient which has an elongate core member with a flexible body member disposed on a distal section thereof. In one embodiment, the distal section of the elongate core member has at least one flexible segment with at least one pair of opposed tapered or parallel faces. Preferably the flexible segment with the tapered or parallel faces is disposed at the distal end of the elongate core and forms a shapable segment.

    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： A guidewire formed at least in part of a superelastic member with a section having one or more altered properties including physical and mechanical properties. Preferably, the section of altered property has reduced superelasticity with respect to the remainder of the superelastic member. The invention also comprises method of manufacturing such guidewires wherein a section of the superelastic member is isolated and treated to change one or more of the properties. The treatment may be alloying with a diffusable element or isolating one or more sections to work and heat treat to decrease superelasticity relative to the rest of the member. The section having one or more altered properties is preferably a distal portion of the member, for example about the most distal 3 cm.

    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.

    摘要： 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 pseudoelastic 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.
