  • Publication number: 20170088988
    Abstract: Methods of braiding using a braiding mechanism are described. The braiding mechanism includes a circular array of filament engagement elements, a mandrel extending from the center of the circular array, a plurality of actuators disposed operably about the circular array, and a rotating mechanism adapted to rotate one or more filaments. The circular array of filament engagement elements and the plurality of actuators are configured to move relative to one another. The plurality of filaments are loaded onto the mandrel and extend radially toward and contact the circumferential edge of the circular array of filament engagement elements. The plurality of actuators are operated to engage a first subset of the plurality of filaments and move the engaged filaments in a generally radial direction to a position beyond the circumferential edge of the circular array. The rotating mechanism is operated to move the engaged filaments about the mandrel axis.

  • Patent number: 9528205
    Abstract: A braiding machine and methods of braiding are described. The braiding machine includes first and second annular members having inclined surfaces, the second annular member being concentric with the first annular member. The inclined surfaces are inclined at a non-zero angle formed between an axis of the outer ring and a horizontal axis that lies perpendicular to the longitudinal axis of the mandrel. Each of the annular members has a plurality of tubular guide wires slideably mounted thereon and a plurality of wires extend from the mandrel through each of the tubular wire guides. One of the first and second annular members rotates circumferentially relative to the other. The first plurality of tubular wire guides slides radially inward so as to align with the second annular member, and the second plurality of tubular wire guides slides radially outward so as to align with the first annular member.

  • Publication number: 20160287276
    Abstract: A device and method for intravascular treatment of an embolism, and particularly a pulmonary embolism, is disclosed herein. One aspect of the present technology, for example, is directed toward a clot treatment device that includes a support member having a plurality of first clot engagement members and second clot engagement members positioned about the circumference of a distal portion of the support member. In an undeployed state, individual first clot engagement members can be linear and have a first length, and individual second clot engagement members can be linear and have a second length that is less than the first length. The clot engagement members can be configured to penetrate clot material along an arcuate path and hold clot material to the clot treatment device.

    Abstract: The invention concerns a method and device for controlling the switching operation in a switch mode power supply module. The switch mode power supply module is intended to supply power to an item of equipment. The method comprises the steps of measuring, in the switch mode power supply module, the load current and comparing the measured load current with a predefined load current threshold value, and, cyclically interrupting the switching operation if the measured load current inside the device is less than the predefined load current threshold value.

  • Publication number: 20160158009
    Abstract: Embodiments of the present disclosure provide a delivery apparatus for delivering a prosthetic heart valve to a native valve site via the human vasculature without the need for a separate introducer sheath. The delivery apparatus is particularly well-suited for advancing a prosthetic valve through the aorta (i.e., in a retrograde approach) for replacing a stenotic aortic valve.

  • Patent number: 9287932
    Abstract: The external power supply comprises a modem, a power source for providing an operating voltage for the modem and a supply voltage for an appliance and a power safe control. The power safe control comprises a current sense element for sensing a supply current of the supply voltage and a threshold circuit coupled to the current sense element for switching off the operating voltage when the supply current is below a threshold value, and for switching on the operating voltage when the supply current is above the threshold value. The appliance is in a preferred embodiment a residential gateway or a set-top box and the modem a power line communication modem.

  • Publication number: 20150333626
    Abstract: The invention relates to switch mode power supply modules and items of equipment powered by these modules. The power supply module comprises means for cyclically interrupting the switching operation, during a so-called switching operation interruption phase, if the load current of the module is less than a current threshold value and sustaining the switching operation, during a so-called switching operation phase, if the load current is greater than the load current threshold value and means for ending the switching operation interruption phase if the power supply voltage of the item of equipment is greater than a voltage threshold value. The item of equipment powered by the module comprises a capacitive element able to store energy from the module during the switching operation phase and means for releasing the energy stored between the output terminals of the power supply module when it receives an activation signal.

  • Publication number: 20150024476
    Abstract: Apparatus and Methods are provided for a microfabricated fluorescence activated cell sorter based on a switch for rapid, active control of cell routing through a microfluidic channel network. This sorter enables low-stress, highly efficient sorting of populations of small numbers of cells (i.e., 1000-100,000 cells). The invention includes packaging of the microfluidic channel network in a self-contained plastic cartridge that enables microfluidic channel network to macro-scale instrument interconnect, in a sterile, disposable format. Optical and/or fluidic switching forces are used alone or in combination to effect switching.

  • Publication number: 20150006928
    Abstract: The invention relates to a device and a method for sequentially starting USB peripherals in order to optimise the supply of electrical power. Using current profiles corresponding to the start-up of peripherals, the connected peripherals are started one after the other. The delay between each start-up corresponds to the time necessary for the current consumption stabilisation of the peripheral being started. The profiles are stored by the device. During the start-up, the invention identifies the connected peripheral and searches for its start-up profile in the stored profiles, in order to determine the start-up delay to apply to the next peripheral.
