Abstract: A temporary and retrievable radiopaque marker and discrete radiopaque marker for use on an implantable endoprosthesis. The elongate marker has a proximal end, a distal end, and a thickness. At least a portion of the marker is radiopaque and the marker is removably-attached to the implantable endoprosthesis.

Abstract: A delivery device for delivering an implantable endoprosthesis with an occlusion region for occluding fluid flow to a desired location in a body lumen. The delivery device includes an outer sleeve and an inner tube terminating at a distal tip. The distal tip is made of one of a dissolvable, bioabsorbable, or deformable material. Upon deployment of the endoprosthesis at the desired location, the shape of the distal tip is altered to a different shape and withdrawn through the constricted region of the endoprosthesis.

Abstract: A temporary bioabsorbable-radiopaque marker for use on an implantable endoprosthesis. The bioabsorbable-radiopaque marker is adapted to be disposed on or adjacent an implantable endoprosthesis in a body lumen for a predetermined amount of time until the bioabsorbable and radiopaque materials are absorbed or dispersed in the body.

Abstract: A self-expanding stent formed from helically wound and braided filaments of bioabsorbable polymers such as PLA, PLLA, PDLA, and PGA.

Abstract: A body compatible stent is formed of multiple filaments arranged in two sets of oppositely directed helical windings interwoven with one another in a braided configuration. Each of the filaments is a composite including a central core (24) and a case (26) surrounding the core (24). The core is formed of a radiopaque and relatively ductile material, in particular gold or a gold alloy. The outer case (26) is formed of a relatively resilient material, e.g. a cobalt/chromium based alloy. Favorable mechanical characteristics of the stent are determined by the case (26), while the core (24) enables in vivo imaging of the stent. The composite filaments are formed by a drawn filled tubing process in which the core (24) is inserted into a tubular case (26) of a diameter substantially more than the intended final filament diameter. The composite filament is cold-worked in several steps to reduce its diameter, and annealed between successive cold-working steps.

Abstract: A method for treating a body vessel using a stent formed from filaments of titanium or titanium alloys such as Ti—13Zr—13Nb.

Abstract: A temporary bioabsorbable-radiopaque marker for use on an implantable endoprosthesis. The bioabsorbable-radiopaque marker is adapted to be disposed on or adjacent an implantable endoprosthesis in a body lumen for a predetermined amount of time until the bioabsorbable and radiopaque materials are absorbed or dispersed in the body. The bioabsorbable material may include polylactide and the radiopaque material may include bismuth trioxide and barium sulfate. The weight percent of the radiopaque material in the bioabsorbable material may range from about 1% to about 80%. The radiopaque material may have a linear attenuation coefficient of from about 10 cm−1 at 50 KeV to about 120 cm−1 at 50 KeV.

Abstract: A balloon catheter having a perfusion lumen communicating with a blood vessel, and a magnetically driven impeller disposed in the perfusion lumen to increase blood flow through the catheter and the arteries.

Abstract: A bioabsorbable implantable endoprosthesis having elongate elements including hollow, cavity or porous portions adapted to accumulate by-product from the degradation of the bioabsorbable material and shortening the diffusion distance for water absorption and thereby relatively increasing the degradation of the structure.

Abstract: A self-expanding stent formed of helically wound and braided filaments of wrought cobalt, chromium and molybdenum alloy containing less than about five weight percent nickel. The composition of the alloy from which one embodiment of the stent is formed is Co-26Cr-6Mo-1Si-1Fe-1Mn-1Ni.

Abstract: A process for producing high density refractory metal warhead liners from near net shape blanks. A shaped mold is filled with pure or solid solution molybdenum or tungsten powders. The powders may be isostatically pressed and sintered to form a near net shape blank. A hot isostatic press may be used in combination with these steps or by itself to form the near net shape blank. The hot isostatic press densifies the near net shape blank to at least 90% of theoretical density. Where wrought properties are desired, a final forging step is performed. Alternatively, a process such as vacuum plasma spraying may be used to form the near net shape blank. A hot isostatic press densifies the near net shape blank. A final machining step achieves a finished refractory metal warhead liner.

Abstract: In a method of making a load-bearing article by spray casting a molten metal onto a metal substrate, the substrate surface receiving the spray cast deposit is treated by vacuum cleaning, boronizing and/or knurling to enhance the structural integrity of the diffusion bond joint subsequently formed between the spray cast deposit and the substrate in sustaining a load across the joint without premature joint failure.
