    摘要： The present invention is directed to the fabrication of a test apparatus and the test apparatus itself. The test apparatus is designed to be a component used in a durability/fatigue testing unit. One such test apparatus made in accordance with the present invention is a life-size model of an Abdominal Aortic Aneurysm made with any rapid prototyping process that creates solid freeform parts with flexible material. A preferred rapid prototyping process used to make the AAA model in accordance with the present invention is the process known as selective laser sintering (SLS), while the preferred material used in said process is an elastomeric polymer.

    摘要： Systems and methods for fatigue testing one or more stents based on measured electrical resistance levels of each stent. Pairs of lead lines from an ohmmeter are connected to a respective stent. The respective stent is mounted onto an expander having an interior tapered portion into which a correspondingly tapered expansion pin is received. Cyclic loading strains are applied to the respective stent as an expansion pin is inserted into a corresponding one of the expanders. Stent fracture or failure occurs when cyclic loading exceeds the stents architectural and material capacity. Such fracture fatigue or failure is identified by increased electrical resistance levels. Resistance may be continuously monitored to more readily identify the onset of fatigue or failure. The expansion pins extend from a movable plate, and the expanders comprise a part of corresponding stations that extend from a fixed plate.

    摘要： A biocompatible solid-solution alloy may be formed into any number of implantable medical devices. The solid-solution alloy comprises a combination of elements in specific ratios that make it magnetic resonance imaging compatible while retaining the characteristics required for implantable medical devices. The biocompatible solid-solution alloy is a Cobalt-Chromium alloy having substantially reduced Iron, Silicon, Phosphorous and Sulfur content.
