  • Patent number: 10456518
    Abstract: A cannula includes at least one opening at a distal tip, and further includes multiple fenestrations that are maintainable in position substantially immediately or slightly beyond a site or point of cannula entry into a vessel. The fenestrations, in combination with the opening(s) at the cannula's distal tip, enable the simultaneous perfusion of blood into the cannulated vessel along multiple directions, including opposing or anti-parallel blood flow directions relative to a central axis of the cannulated vessel. During a medical procedure (e.g., an extra-corporeal membrane oxygenation (ECMO) procedure) blood introduced into a vessel such as the femoral artery by way of the cannula can thus exit the cannula in a manner that provides concurrent blood flow in a first direction towards the heart and a second direction away from the heart.

  • Patent number: 10426642
    Abstract: A membrane for covering a peripheral surface of a stent is provided, the membrane including a plurality of line openings formed therein. Each line opening may be a straight line opening, for example in the form of a slit, a curved line opening, or any line opening of a suitable shape or curvature, e.g. U-shaped or V-shaped. Blood pressure opens the slits to allow blood to flow through the membrane, while curved line openings create a flap in the membrane that can open to allow blood to pass through. According to further embodiments of the present invention, a method of forming a membrane on a stent and a device for use in a blood vessel are provided.

  • Publication number: 20190259799
    Abstract: An image sensor includes a sensor portion and an ASIC portion bonded to the sensor portion. The sensor portion includes a first substrate having radiation-sensing pixels, a first interconnect structure, a first isolation layer, and a first dielectric layer. The ASIC portion includes a second substrate, a second isolation layer, and a second dielectric layer. The material compositions of the first and second isolation layers and the first and second dielectric layers are configured such that the first and second isolation layers may serve as barrier layers to prevent copper diffusion into oxide. The first and second isolation layers may also serve as etching-stop layers in the formation of the image sensor.

  • Publication number: 20170049997
    Abstract: Defining proximal as toward the heart and distal as away from the heart, a sheath includes a proximal opening and multiple fenestrations maintainable in position slightly beyond a site or point of sheath entry into a vessel by way of an anchoring assembly having a set of radially displaceable anchoring elements configured for abutting a superficial vessel wall. The fenestrations and/or anchoring element(s) are arranged obliquely or non-obliquely around peripheral portions of the sheath. The sheath can receive blood from a pumping source at a proximal opening, and channel the blood toward, to, and through the fenestrations. The fenestrations, in combination with the proximal opening, enable the perfusion of blood into the cannulated vessel in a set of distal directions for perfusing a distal tissue or organ. Flow of blood out of fenestrations directs blood distally towards the limb, head, or other distal region, mitigating the risk of or preventing ischemia.

  • Publication number: 20170007800
    Abstract: A cannula includes a first segment configured to reside entirely within a vessel. The first segment includes a proximal exit opening disposed nearer to the heart, and multiple fenestrations disposed distally away from the proximal exit opening near a cannulation site. The fenestrations in combination with the proximal exit opening enable simultaneous perfusion of blood into the cannulated vessel along proximal and distal directions. During a medical procedure, blood introduced into a vessel (e.g., the femoral artery) by way of the cannula can exit the cannula in a manner that provides concurrent blood flow in a first set of directions proximally towards the heart and a second set of directions distally away from the heart. Radially displaceable anchoring elements positionable adjacent to the vessel's superficial wall aid retention of the first segment in the vessel. The fenestrations and/or anchoring elements can be arranged obliquely around portions of the cannula's circumference.

  • Patent number: 9475212
    Abstract: A mold vacuum valve device includes a first mold having a mounting hole formed therethrough, a second mold connected to the first mold, and a sliding block. The second mold has a shaping cavity, a runner passage in fluid communication with a side of the shaping cavity, and a vacuum passage in fluid communication with an opposite side of the shaping cavity. The shaping cavity is defined by a serrated bottom wall surface, and cooperates with the mounting hole to define an accommodating space. The sliding block is disposed movably within the accommodating space, and has a head portion and a body portion. The head portion has a serrated side surface complementary to the serrated bottom wall surface. The head portion cooperates with the second mold to define a shaping clearance.

  • Patent number: 9409189
    Abstract: A modular cyclonic separator comprises separating tubes each including an air-guiding impeller that is fixed coaxially in an outer tube body and that is formed with spiral channels for causing an airflow, which flows radially into the separating tube, to follow a cyclonic flow pattern through a separating chamber in the separating tube, thereby separating some of solid impurities from the airflow within the separating chamber. Each separating tube is capable of connecting selectively with one or two three-port valves to form a first or second filtration module, in which the airflow passes through a fluid passage in the one three-port valve or one of the two three-port valves prior to entering the separating tube.
