  • Publication number: 20200038103
    Abstract: A fluid delivery balloon ablation catheter configured to allow uniform fluid distribution through each electrode by varying the diameter of the main lumen. The catheter comprises an elongated tubular catheter body having a distal end, a proximal end, and a lumen extending longitudinally within the catheter body. A number of elution holes are provided in the catheter tip region, and these holes are in fluid communication with the lumen through ducts. As such, cooling fluid is delivered from the pump, through the lumen through the ducts, and out of the holes to the environment outside of the catheter. The main lumen has at least one tapered flow constrictors to restrict flow of fluid towards the distal region of the lumen. The catheter has multiple half-dome balloons, with the distal balloon being the smallest, and the proximal balloon being the largest balloon. The multiple-balloon catheter helps when using the ablation catheter in a funnel-shaped vessel.

  • Publication number: 20200026634
    Abstract: Techniques and mechanisms are disclosed that enable a data intake and query system to generate and cause display of circular timelines of timestamped event data. As used herein, a circular timeline generally refers to a graphical display of timestamped events stored by a data intake and query system, wherein the timestamped events may be displayed as arcs of one or more concentric circles and located in a circular timeline area according to a chronological ordering associated with the events. One or more display attributes of each arc may further depend on other data associated with the corresponding events. For example, each arc of a circular time may be displayed at a particular radial distance, with a particular thickness, using a particular shading and/or color, etc., depending on various data values associated with the one or more events represented by the arc.

  • Patent number: 9946492
    Abstract: A data processing system 2 including non-volatile memory 22 manages the ordering of writes to the non-volatile memory and persist barrier instructions using a persist buffer storing persist buffer data. A write controller responds to the persist buffer data to prevent writing to the non-volatile memory for instructions following a given persist barrier instruction within a sequence of program instructions before the writes to the non-volatile memory which precede that given persist barrier instruction have at least been acknowledged as received by the memory system containing the non-volatile memory. In the case of a multi-core system, cache snooping mechanisms are used to pass persistency dependence data between cores such that strong persist atomicity may be tracked and managed between the cores.
