  • Patent number: 10939272
    Abstract: A system and method for managing jobsite personnel is presented. An application registers Wi-Fi enabled mobile devices on a geographically-defined jobsite, associates them with individual workers, and associates the workers' devices with the particular jobsite. The application logs registered devices when the devices come within the physical boundaries of the associated jobsite. An administrator may receive reports on all registered mobile devices. In an emergency requiring jobsite evacuation, a server communicates to each logged mobile device a message requiring time-sensitive compliance. Compliance is tracked and recorded. The server can provide to the administrator one or more compliance reports.

  • Patent number: 9427557
    Abstract: A stent delivery catheter for positioning a stent across a lesion of a blood vessel is disclosed. The catheter includes an inflation balloon coupled to a distal region of the elongate shaft of the catheter and a stent loaded on the inflation balloon. The catheter may also include an occlusion balloon having a proximal waist secured to the elongate shaft and a distal waist secured to the elongate shaft. The occlusion balloon includes a first folded-over portion extending distal of the distal waist to a distalmost extent of the occlusion balloon and a second folded-over portion extending proximal of the proximal waist to a proximalmost extent of the occlusion balloon. The catheter further includes a fluid discharge port located distal of the occlusion balloon for discharging a lubricious fluid exterior of the elongate shaft toward the stent to facilitate advancing the stent across an occlusion.

  • Patent number: 8292900
    Abstract: A vessel bifurcation wire assist device and related methods of advancing guidewires into main and branch vessels of a vessel bifurcation. The wire assist device includes a first guidewire housing member defining a first guidewire lumen sized to advance over a first guidewire, and a second guidewire housing member defining a second guidewire lumen sized to advance over a second guidewire. The second guidewire housing member has a first directional arrangement and a second directional arrangement. The first directional arrangement provides a parallel arrangement of the second guidewire relative to the first guidewire housing member, and the second directional arrangement provides an angled arrangement of the second guidewire relative to the first guidewire housing member.

  • Patent number: 7571023
    Abstract: An apparatus for counting pharmaceutical units is provided having a supporting deck assembly, a hopper, a cylindrical chamber and a transport ring positioned between the hopper and the cylindrical chamber, wherein the hopper has a tilted floor, which can be shaken or vibrated to discharge the units on to a transport ring, and the transport ring is sloped downward from its inner to outer perimeter, which brings the units into contact with the undulating surface of the walls of the cylindrical chamber to promote singulation prior to counting.

  • Publication number: 20080065196
    Abstract: The present invention is directed toward a stent having a plurality of axially spaced serpentine bands, each serpentine band having an axis circumferentially oriented around the longitudinal axis of the stent. The serpentine bands have a plurality of struts spaced along the axis of the serpentine band forming alternating peaks and troughs. The serpentine bands are interconnected via a plurality of interconnecting struts to form a plurality of cells defined by axially adjacent serpentine bands and circumferentially adjacent interconnecting struts. When the stent is in its unexpanded state, each serpentine comprises a plurality of slits, each slit being non-linear and continuous from a first end to a second end and being formed in at least a portion of each of three consecutively connected struts. Upon expansion of the stent to its expanded state, each of the slits expands in size to form an intra-columnar cell (ICC).

  • Publication number: 20070225514
    Abstract: The removal of excess water from organic materials, specifically distillers grains, employing the use of supercritical carbon dioxide. The method includes the use of an extraction chamber, in which organic material containing excess moisture is subjected to a supercritical carbon dioxide loop which in turn solubilizes some of the water. Supercritical carbon dioxide enters the extraction chamber to offset the saturated, supercritical carbon dioxide which is removed from the extraction chamber. Upon exiting the chamber, the water is separated from the saturated supercritical carbon dioxide, after which the water depleted carbon dioxide is then returned to the extraction chamber again in the supercritical state; thus creating a carbon dioxide process loop.
