    摘要： A joint and a laminate including a nickel-titanium alloy such as Nitinol and a method for preparing the surface of a nickel-titanium alloy member for bonding solder material and, electively, another similar or dissimilar member thereto. The method includes applying a halogen containing flux to the titanium oxide coated surface of a nickel-titanium alloy member and heating the flux to its activation temperature. The flux removes and suspends the titanium oxide therein and deposits a metal from the halogen containing flux on the oxidation free surface. The activated flux also coats the member surface for protection from further oxidation. A bonding material such as a tin-silver solder is flowed onto the tinned surface to displace the activated flux. Electively, another member is applied to the molten solder to form a joint between the two members. The residual flux is cleaned from the joint to prevent further deterioration of the base metal. The solder joint includes the base nickel-titanium alloy metal, the metal from the halogen containing flux, and the solder material. Electively, any other member may be applied to this joint in the molten state to form a metallic bond therebetween.

    摘要： A wire guide having a generally increasing flexible tip that is resistant to fracture. The flexible tip wire guide comprises a cylindrical wire member having a substantially uniform outer diameter main portion and a distal portion with a tapered outer surface region for gradually increasing the flexibility of the tip and a proximal concave outer surface region that extends tangentially and proximally from the tapered outer surface for increasing the fracture resistance of the decreasing outer diameter distal portion. A flexible wire coil is inserted over the distal wire portion and secured to the proximal end of the distal wire portion and the distal end of the main portion using silver solder with a uniform outer diameter for minimizing potential trauma to vessel walls. The outer diameter of the flexible wire coil is substantially equivalent to the outer diameter of the main portion of the wire guide to likewise minimize trauma to vessel walls. A cylindrical outer surface extends distally from the tapered outer surface of the distal wire portion to add uniform flexibility to the flexible tip for use, e.g., in a J-tip configuration. The distal end of the flexible wire coil is attached to the distal end of the distal wire portion with silver solder or a weld that is hemispherically shaped for minimizing trauma during insertion through the vessel.
