Abstract: The present disclosure is directed to methods for joining initially separate members of different metallic materials, e.g., as in joining segments of a multi-segment intravascular guide wire, as well as multi-segment intravascular guide wires so formed. Initially separate members are provided, which members comprise different metallic materials relative to one another (e.g., stainless steel and nitinol). The members are aligned with one another, and a first force is applied to the members while delivering electrical current through the members to solid state weld the separate members to one another. A follow up force that is greater than the first force is applied as solid-state deformation occurs and a weld nugget forms between the members. The weld nugget so formed is thinner and of a larger transverse cross-sectional area than would be produced without application of the follow up force.

Abstract translation: 本公开涉及用于接合不同金属材料的初始分离构件的方法，例如在多段血管内导丝的接合段中以及如此形成的多段血管内导丝。 最初提供分离的构件，这些构件相对于彼此包括不同的金属材料（例如，不锈钢和镍钛诺）。 构件彼此对准，并且第一力施加到构件，同时将电流通过构件传递到固态，将分离的构件彼此焊接。 当发生固态变形时，施加大于第一力的跟随力，并且在构件之间形成焊接熔核。 如此形成的焊接熔核与较大的横截面面积相比，不会产生后续的力。

Abstract: Embodiments are directed to radiopaque implantable structures (e.g., stents) formed of cobalt-based alloys that comprise cobalt, chromium, tungsten, and nickel, and methods for their manufacture. Tungsten is present above its solubility limit (about 15%) at ambient temperature, but is still only present as a super-saturated, primarily single-phase material exhibiting an FCC microcrystalline structure.

Abstract: A catheter having an elongated shaft and a balloon on a distal shaft section, the elongated shaft comprising an outer tubular member, and an inner tubular member which has a bonded portion along which an outer surface of the inner tubular member is bonded to an inner surface of the outer tubular member. The inner tubular member has a proximal portion proximal to the bonded portion, and a distal portion distal to the bonded portion with higher axial compression stiffness and column strength than the proximal portion thereof. The catheter has improved trackability, axial collapse resistance, pushability, and crossability, for improved ability to position the balloon at a desired location in a patient's body lumen.

Abstract: Elongate, flexible catheter includes a shaft having a proximal end, a distal end, and a lumen extending therein. The shaft has an inner layer comprising an amorphous polyamide having a Shore D durometer value of greater than 78, and an outer layer comprising a semi-crystalline polyamide or copolyamide having a Shore D durometer value of less than 76. The outer layer is thinner than the inner layer. The shaft has an increased resistance to kinking as compared to a similar shaft of a single layer of the amorphous polyamide having a Shore D durometer value of greater than 78.
