Abstract: A catheter system and method for implanting an endoprosthesis such as a stent at a treatment site in a patient's body lumen. The catheter provides a complete system for stent delivery, dilatation, and delivery and/or recovery of an expandable device, such as an embolic protection device, adjacent to the treatment site in the body lumen.

Abstract: A nickel-titanium alloy having a large, superelastic operating temperature window or range. The nickel-titanium alloy includes at least an additional element such as platinum, palladium, manganese, boron, aluminum, tungsten, and/or zirconium. When processed through heat treat and area reduction steps, the resultant alloy exhibits a wide superelastic temperature operating window if the characteristics of the alloy when plotted on a temperature versus stress curve can be expressed as UP=(0.66 ksi/° C.)(T)+σ0, with R2≧0.98, wherein σ0 is the upper plateau stress of the alloy at about 0° C., R2 is the coefficient of determination, and UP is the upper plateau stress of the alloy.
