  • Publication number: 20240216600
    Abstract: A catheter system can include a tubular body, and at least one of a targeting system coupled to the tubular body, an expandable member, or a fluid injection port. A method of identifying a bifurcation can include inserting a catheter system into a first vessel, positioning the catheter system at a first location, expanding an expandable member to occlude the first vessel, delivering contrast material so the contrast material pooling proximate to the expandable member, and reviewing a shape of the contrast material in the first vessel under fluoroscopy.

  • Patent number: 11850379
    Abstract: A launching catheter for targeting a second vessel from a first vessel includes a catheter including a proximal portion and a distal portion including a needle aperture and a flat rectangular radiopaque marker. The flat rectangular radiopaque marker disappears under fluoroscopy upon rotation to provide information about rotational alignment of the launching catheter. The launching catheter includes a needle configured to extend through the needle aperture. A method of aligning the catheter includes rotating the catheter in a first blood vessel until the marker has a thickness (e.g., minimal thickness) under fluoroscopy. The thickness indicates rotational alignment of the catheter.

  • Publication number: 20230225732
    Abstract: Devices and methods divert blood flow from a first vessel to a second vessel and maintain blood flow in the first vessel. The device includes a first segment and a second segment. The first segment is configured to anchor in the first vessel. The first segment includes a window to allow blood to flow into the first segment, through the window, and distal in the first vessel. The second segment is configured to anchor in the second vessel. The second segment is configured to allow blood to flow into the first segment, through the second segment, and into the second vessel.

  • Patent number: 10766629
    Abstract: An architecture of a propulsion system of a multi-engine helicopter is disclosed, comprising turboshaft engines that are connected to a power transmission gearbox. It comprises: a hybrid turboshaft engine that is capable of operating in at least one standby mode during a stable flight of the helicopter; a pack for quickly restarting said hybrid turboshaft engine in order to bring said engine out of said standby mode and to reach a nominal operating mode; an auxiliary power unit that is connected to said electrotechnical restart pack by means of a first AC/DC converter and is capable of providing said restart pack, on demand, with power required for bringing said hybrid turboshaft engine out of said standby mode.

  • Patent number: 10087838
    Abstract: A device and a method of temporarily increasing power of at least a first turbine engine is disclosed. The device includes a coolant liquid tank and a first injection circuit connected to the tank and leading to at least one injection nozzle suitable for being installed upstream from at least one compressor stage of the first turbine engine. This first injection circuit includes at least a first flow valve configured to open when a pressure exceeds a predetermined threshold compared with a downstream pressure from at least one compressor stage of a second turbine engine so as to enable the coolant liquid to flow towards the injection nozzle of the first injection circuit.
