    摘要： A composite stent having a substrate tube made of stainless steel, a nickel-cobalt-chromium-molybdenum alloy, or chonichrome with at least one metal cladding tube is disclosed. Specifically, the substrate tube is placed within a metal cladding tube made of platinum, gold, tantalum, tungsten, platinum-iridium, palladium, or nickel-titanium, preferably with an interference fit therebetween. The composite, laminate tube then undergoes a series of rolling or cold drawing processes interspersed with heat treating to release built up stresses. When the final diameter of the laminate tube is reached, the cladding has been laminated to the exterior of the substrate tube by a bond generated from the rolling and/or cold drawing operations. The finished laminate tube is then cut by laser cutting or chemical etching to form a suitable stent pattern.

    摘要： Devices and methods for passing optical radiation into and out of a body lumen which can include a rotatable ferrule for use in an optical guidewire and methods for using a rotation ferrule. The rotatable ferrule may be either rotatably captured by and free to rotate within a guidewire, or may rotate upon release from a releasable, mechanically stable friction-fit engagement with a guidewire. Sterile interfaces for readily connecting and disconnecting an optical guidewire with and from other optical instrumentation while maintaining the sterility of the guidewire are provided as well as methods for using a sterile interface device. Interface devices can provide either direct or indirect optical and mechanical connection between an optical guidewire and peripheral instrumentation.

    摘要： The disclosure is directed to a guidewire having an elongate core member with at least one distally tapered portion at the distal section, with a flexible body member disposed around said distal section. The flexible body member is preferably comprised of a metallic helical coil that has proximally tapered portion at the proximal end, with a diameter similar to the outer diameter of the elongate core member at the point of attachment thereto. The distal end of the flexible body member is attached to the distal end of the elongate core member. The proximal taper of the flexible body member provides a smooth transition from the elongate core member to the flexible body member while minimizing the amount of bonding material needed and the resulting localized stiff portion at the point of connection between the proximal end of the flexible body member and the elongate body member.

    摘要： The invention is directed to a guidewire having a distal section with multiple distally tapered core segments with at least two contiguous distally tapering core segments in which the most distal tapered core segment preferably has a greater degree of taper than the proximally contiguous tapered core segment. The invention is also directed to an elongated intracorporeal device, preferably a guidewire or section thereof, that has a core member or the like with a plurality of contiguous tapered segments having taper angles that are configured to produce a linear change in stiffness over a longitudinal section of the device. The device may also have a core section with a continuously changing taper angle to produce a curvilinear profile that preferably is configured to produce a linear change in stiffness of the core over a longitudinal section of the device.

    摘要： Optical windows for intracorporeal devices, intracorporeal devices comprising a window and a method for forming a window for an intracorporeal device are provided. The method comprises placing within a mold an assembly comprising a mandrel located within a pair of parts separated by a collar of window material, heating the window preform effective to cause the window material to soften, and applying force to urge together the pair of parts to deform the window material so as to form a window. The intracorporeal devices, such as imaging devices, include guidewires, catheters, endoscopes. In addition, the method is suitable for joining plastic parts to other parts, such as metal and ceramic parts.
