    摘要： An intracorporeal device, preferably a guidewire, and method of making same that has an elongate inner core element with an outer layer of material disposed about the core element. The layer of material can be applied as a braid, strand or smooth layer of material, and is preferably a metal. If the layer of material is applied as a braid or strand, it may be subsequently cold drawn so as to create a smooth layer from the braid or strand. The inner core element, may be homogeneous, or may consist of drawn filled tubing with at least two layers of material, preferably biocompatible metals. In this way, the multiple layer distal section of the elongate core can be shaped or ground so as to achieve the desired mechanical properties and provide surfaces for attachment of components that are readily bonded or soldered to.

    摘要： The present invention is directed to an intracorporeal device, preferably a guidewire, and method for making the same. The device, has proximal and distal ends and includes an elongated high strength proximal portion having proximal and distal ends. The device further includes a distal portion having proximal and distal ends. The distal end of the proximal portion and the proximal end of the distal portion are connected by a connector. The distal portion is formed of a superelastic alloy composition. Preferably, the connector is also formed of the superelastic alloy composition. The superelastic alloy composition includes, in atomic percent, from about 28 to about 52% nickel, from about 48 to about 52% titanium, and up to about 20% of at least one alloying element selected from the group consisting of palladium, chromium, and hafnium.

    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.
