Abstract: A stent graft device that includes a frame, a cover material covering the frame, and an anchoring member having an adjustable geometry is provided. The anchoring member may be incorporated as part of the frame or coupled thereto. The anchoring member may be formed of a material having a tensile strength such that it can be bent, straightened, or otherwise changed in shape.

Abstract: A multi-tool positioning and manufacturing system moves a workpiece among many tools, such as grinding wheels, each of which performs a manufacturing operation on the workpiece. The system moves the workpiece automatically, quickly, repeatably, and precisely among the tools, without any manual intervention. It can perform the same manufacturing operations as many separate tools, such as grinding the inner diameter, outer diameter, and rib of a tapered roller bearing cone. Because a machinist does not have to move the workpiece between machines for different operations, the total manufacturing process can be faster and higher yield than with separate tools. The system can also move a single dresser among the tools for dressing and truing, further increasing manufacturing efficiency by eliminating the need for separate dressers for separate tools.

Abstract: A gas sampler device has a top plate with a concaved outer wall. The concaved outer wall allows users easily to lift the top plate off of the bottom plate without disturbing the bottom plate because the curved surface permits more positive contact between the outer wall and users' fingers. Moreover, the weight of the top plate is reduced by approximately twenty percent compared to conventional top plates, a feature that also makes it easier for users to lift the top plate off of the bottom plate.

Abstract: A stent incorporating flexible, preferably polymeric, connecting elements into the stent wherein these elements connect adjacent, spaced-apart stent elements. Preferably the spaced-apart adjacent stent elements are the result of forming the stent from a helically wound serpentine wire having space provided between adjacent windings. Other stent forms such as multiple, individual spaced-apart ring-shaped or interconnected stent elements may also be used. The connecting elements are typically web-shaped and result from creating slits or apertures in a covering of graft material applied to the stent and then, for example, applying heat to cause the slits or apertures to enlarge. The remaining graft material forms the interconnecting webs between the adjacent stent elements.
