    Abstract: Radiopaque cobalt-based alloys having a smooth electropolished surface with rounded edges and methods for electropolishing such alloys. A cobalt-based alloy includes cobalt, chromium, and one or more radiopaque elements. In one embodiment, examples of radiopaque elements include so-called platinum group metals (i.e., platinum, palladium, ruthenium, rhodium, osmium, or iridium). Group 10 elements (i.e., platinum or palladium) are particularly preferred. Because of the presence of the platinum group metal(s), such alloys are generally difficult to electropolish. Electrolyte formulations and methods for electropolishing such alloys are also disclosed.

    Abstract: Catheter including an inner tubular member having a proximal end portion, a distal end portion and an exterior surface. The inner tubular member further has a guidewire lumen defined therein. An outer tubular member is movable relative to the inner tubular member, the outer tubular member has a proximal end, a distal end and an interior surface directed toward the exterior surface of the inner tubular member. A movable tubular structure is disposed between the outer tubular member and the inner tubular member. The movable tubular structure includes a body member having an outer surface with a recess defined therein. The outer tubular member is received within the recess to form a trough along a portion of an exterior surface of the outer tubular member. The trough has a filler disposed therein to couple the outer tubular member to the body member of the movable tubular structure.

    Abstract: 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 psuedoelastic 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.
