  • Patent number: 11712352
    Abstract: A system for deploying a prosthesis over a Carina between an ipsilateral lumen and a contralateral lumen includes a guidewire, a guidewire capture catheter, a self-expanding tubular prosthesis, and a delivery catheter. The guidewire is first placed in the ipsilateral lumen. The guidewire capture catheter is then advanced from the contralateral lumen to a position at or above the ipsilateral lumen. The guidewire is typically advanced through an occlusion, which may be a total occlusion, and captured by a capture element on the guidewire capture catheter. The guidewire capture catheter pulls the guidewire out through the contralateral side, and the guidewire is used to advance a delivery catheter from the ipsilateral side. The delivery catheter delivers a first segment of the tubular prosthesis in the ipsilateral lumen and a second segment of the prosthesis in the contralateral lumen.

  • Patent number: 11151957
    Abstract: This display device is provided with: a gate driver that drives a display panel; and a control circuit that controls driving of the gate driver. The control circuit is provided with: a Voltage supply circuit that supplies a Voltage to the gate driver; and a current detection circuit that detects a current to be supplied to the gate driver. The display device reduces, in stages, the voltage to be supplied to the gate driver, and detects the current to be supplied to the gate driver, and in the cases where the detected current is equal to or lower than a predetermined value or a current increase is detected, the display device acquires a first voltage being supplied to the gate driver, and sets a second voltage as a drive voltage for driving the gate driver, said second voltage being obtained by adding a predetermined voltage to the acquired first voltage.

  • Publication number: 20210059686
    Abstract: A compression device includes an adhesion sheet including an adhesion surface; and a compression member mounted on the adhesion sheet and configured to compress a biological surface. The compression member includes a fixing portion fixed to the adhesion sheet on a side of the sheet opposite the adhesion surface in a thickness direction, and a compression main body portion provided in a portion of the compression member, in a plan view seen along the thickness direction, that does not overlap the adhesion sheet. The compression main body is configured to protrude or be protrusible further toward one side in the thickness direction than the adhesion surface. The adhesion sheet includes a first portion to which the fixing portion is fixed and a second portion to which the fixing portion is not fixed. The second portion is provided on at least a compression main body portion side of the adhesion sheet.
