  • Patent number: 10608090
    Abstract: A method of forming a memory device with memory cells in a memory area, and logic devices in first and second peripheral areas. The memory cells each include a floating gate, a word line gate and an erase gate, and each logic device includes a gate. The oxide under the word line gate is formed separately from a tunnel oxide between the floating and erase gates, and is also the gate oxide in the first peripheral area. The word line gates, erase gates and gates in both peripheral areas are formed from the same polysilicon layer. The oxide between the erase gate and a source region is thicker than the tunnel oxide, which is thicker than the oxide under the word line gate.

  • Publication number: 20200046487
    Abstract: A blood conduit with stent has a flexible conduit body and an expandable stent structure. The conduit body has a first opening end through which only an inflow of a blood enters and a second opening end through which only an outflow of the blood leaves. The stent structure includes a plurality of threads adhered to the conduit body and expands in directions intersecting an axial direction of the conduit body. A boundary of one of the threads of the stent structure closest to the second opening end is away from the second opening end with a predetermined distance, thereby preventing blood back flow into the false lumen via a new tear.

  • Publication number: 20190175532
    Abstract: The inventors have unexpectedly discovered that shock and/or potential multi-organ failure due to shock can be effectively treated by administration of liquid high-dose protease inhibitor formulations to a location upstream of where pancreatic proteases are introduced into the gastrointestinal tract. Most preferably, administration is directly to the stomach, for example, via nasogastric tube under a protocol effective to treat shock by such administration without the need of providing significant quantities of the protease inhibitor to the jejunum and/or ileum.
