  • Patent number: 11957355
    Abstract: Vascular access devices, systems, and methods of their use are provided. In one embodiment, a vascular access device includes a catheter, a balloon, and an inflation lumen. The catheter includes an elongate flexible shaft having a proximal end and a distal end with a primary lumen therethrough. The balloon is disposed about the distal end of the catheter. The inflation lumen is in fluid communication with the balloon and extends toward the proximal end of the shaft of the catheter. The balloon is inflatable into a shape having a first open end, a second open end, a sidewall between the first and second open ends, and a passageway therethrough, which, when the balloon is deployed and inflated within a vessel, permits blood flowing in the vessel to flow through the passageway.

  • Patent number: 11550308
    Abstract: Various embodiments are described for dynamic value stream management. A computing environment is directed to receive a stream of metrics from station computing devices each positioned at a station in a manufacturing process, where individual ones of the station computing devices have a sensor configured to generate metrics. The computing environment may determine an optimal allocation of resources for each of the stations in the manufacturing process based at least in part on the metrics. If a cycle time of a station falls below a threshold, personnel from another satisfactorily-performing station may be reassigned to the station based on cross-training metrics. A recommended action for the stations may be determined and presented in a display device.

  • Patent number: 11046611
    Abstract: A calcining kettle includes an outer kettle shell, an inner kettle shell, an interior heat exchanger assembly defining at least one tortuous path inside a volume defined by the inner kettle shell, and an agitator within the inner kettle shell. The inner kettle shell is disposed within the outer kettle shell such that the inner kettle shell and the outer kettle shell together at least partially define a jacket adjacent the inner kettle shell. The inner kettle shell and the interior heat exchanger assembly at least partially define a processing volume. The agitator is configured to rotate at least one paddle to cause movement of a feedstock material within the processing volume. A heating device may be structured and adapted to circulate a heat transfer fluid in the at least one tortuous path and the jacket. Calcining methods are also disclosed.

  • Patent number: 10960188
    Abstract: Treatment methods and devices are provided for percutaneously accessing a patient's thoracic region via a controlled opening in the aorta, so that cardiac procedures, such as a coronary bypass procedure, can be performed in a minimally invasive manner. Advantageously, it may be possible to perform the procedure without placing the patient on cardiopulmonary bypass. The method may include percutaneously delivering at least one catheter into an aorta of a heart, forming a controlled opening in the aorta and pericardium via the at least one catheter to access a thoracic region within the patient's chest, and performing at least one coronary bypass graft procedure through the controlled opening.

  • Patent number: 10866172
    Abstract: A system for producing cryogenic electron microscopy (cryo-EM) grids. A grid holding element holds a cryo-EM grid in place while a sample deposit element deposits liquid sample from a sample supply onto the grid. A sample shaping element shapes the liquid sample and then a cryogenic sample vitrifying element vitrifies the liquid sample. The shaping element may direct a gas jet towards the grid to reduce the thickness of the liquid sample. The gas jet may mix first and second liquid samples together in midair or on the grid. A storage element stores vitrified cryo-EM grids and includes an electromagnetic field (EMF) source that creates an EMF within the storage element such that the vitrified sample is exposed to the EMF. As a result of being exposed to the EMF, a protein provided with the sample is re-oriented from a first orientation to a second orientation.

  • Publication number: 20200303162
    Abstract: An electron microscope (EM) preparation and imaging system including an EM device and a sample preparation device for forming a vitreous ice layer containing a liquid sample through vitrification, which are located within a sealable environment. The sample preparation apparatus includes a cryogenically-cooled stage that receives a sample deposit surface, such as a cryo-EM grid, which is cryogenically cooled through direct contact with the stage. A sample dispenser is movable with respect to the stage and is configured to deposit a liquid sample onto the sample deposit surface at a selected rate of deposition. Once the liquid sample is deposited onto the sample deposit surface by the sample dispenser, it is vitrified automatically in place.

  • Patent number: 9556040
    Abstract: A system is provided to control fluid flow in a wastewater treatment system through wastewater level manipulation. The wastewater treatment system may include a wastewater treatment plant connected to a plurality of pump stations by a main. Each of the plurality of pump stations may include a wet well with a pump therein. The system may include a central server in communication with a sensor to sense a level of wastewater within the wet well. The pump may be automatically moved to an on position when the level of the wastewater in the wet well is at or above a first level and may be automatically moved to an off position when the level of the wastewater in the respective wet well is at or below a pump cutoff level. The central server may systematically manipulate the first level to selectively set the level of wastewater within the wet well.
