Patent number: 11957355Abstract: 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.Type: GrantFiled: January 26, 2022Date of Patent: April 16, 2024Assignee: Access Flow Systems, LLCInventor: L.

Patent number: 11550308Abstract: 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.Type: GrantFiled: January 29, 2021Date of Patent: January 10, 2023Assignee: Dynamic Flow Systems, LLCInventors: Himanshu Srivastava, Brandon Flexsenhar

Patent number: 10866172Abstract: 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.Type: GrantFiled: July 24, 2020Date of Patent: December 15, 2020Assignee: Neptune Fluid Flow Systems LLCInventors: Trevor Allen McQueen, Winnie Liang

Publication number: 20200303162Abstract: 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.Type: ApplicationFiled: March 19, 2020Publication date: September 24, 2020Applicant: Neptune Fluid Flow Systems LLCInventors: Trevor Allen McQueen, Winnie Liang
