Abstract
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.
