    摘要： An implantable medical device includes a structural body made from a superelastic material and includes one or more marker holders integrally formed on the structural body. Each marker holder is designed to hold a radiopaque marker which has a level of radiopacity greater than the superelastic material. The radiopaque marker can be made from a nickel-titanium alloy which includes a ternary element. The ternary element can be selected from the group of elements consisting of iridium, platinum, gold, rhenium, tungsten, palladium, rhodium, tantalum, silver, ruthenium, and hafnium. In one form, the marker holder includes a pair of projecting fingers connected together at a notched region to cooperatively create a particular-shaped opening. This opening, in turn, is adapted to receive a similarly shaped portion formed on the radiopaque marker. In one form, the radiopaque marker includes an inner core which is partially, or completely, encased by an outer layer. This inner core can be made from a highly radiopaque material while the outer layer is formed from a material that is easier to weld to the marker.

    摘要： A system prevents oxidation of a laser cut workpiece by utilizing a laser source that utilizes laser source with an inert gas, such as argon or helium, rather than air or oxygen, to create the slots or kerfs which form the pattern cut into the workpiece. The system introduces oxygen gas through the workpiece as it is being laser cut to oxidize any slag or dross created during the laser cutting process. Oxygen or a mixture of oxygen with other gases cools the slag and the workpiece while at the same time oxidizing the slag to either completely burn or partial burn the slag before it strikes an exposed surface of the tubular member.

    摘要： The present invention is a luminal filter including: a plurality of filter elements interconnected so as to form a filter body shaped in a free recovery form and having a plurality of apertures disposed between and defined by the interconnected filter elements. The apertures are dimensioned so as to inhibit a thrombus of a selected size from passing through the apertures and being dimensioned so as to allow blood components smaller than the selected size to pass through the apertures. The filter body includes a first funnel and second funnel coupled at least indirectly coupled together at their small ends.

    摘要： A method for making a device includes providing a tubular member which will be formed into the device, masking at least a portion of the inner surface of the tubular member with a removable sacrificial material, selectively removing a portion of the tubular member and sacrificial material using a laser device, and mechanically removing the sacrificial material from the inner surface of the tubular member. Ultrasonic energy could be applied to a workpiece which is being laser cut to prevent any generated slag from welding itself to an exposed surface of the workpiece. A compressed fluid or gas, such as air, could be used to clean the surface of the laser-cut workpiece to remove slag formation which adheres to the surface of the cut workpiece.
