  • Patent number: 8876855
    Abstract: A system for delivering an implant device to a vascular site in a patient a delivery pusher apparatus, an implant device detachably connected to the delivery pusher apparatus by a tether having a distal end connected to a proximal end of the implant device, wherein the tether is substantially non-tensioned when connecting the implant device to the delivery pusher, and an electrical heating element configured coaxially around at least a portion of the tether, wherein heat generated by the heating element severs the tether at a point near the proximal end of the implant device.

  • Publication number: 20140318354
    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.

  • Patent number: 8691164
    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: 20140058502
    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: 8608730
    Abstract: A thermal treatment medical system including an umbilical having a first portion and a second portion, and a connector including a male coupling body connected to the first portion, the male coupling body having a central shank defining first and second lumens, a female coupling body connected to the second portion, the female coupling body, matable with the male coupling body and defining third and fourth lumens matable to be in fluid communication with the first and second lumens, respectively, to define first and second fluid flow pathways, respectively, through the connector when the male coupling body is mated with the female coupling body. The second fluid flow pathway is co-axially disposed about a central axis coincident with the first fluid flow pathway. The connector includes a mating mechanism for spatially locking the male and female coupling bodies with respect to each other.

  • Patent number: 8430012
    Abstract: A device and method for forming a tubular braid comprising a plurality of filaments. The braiding machine comprises a disc with a mandrel extending from the center in a perpendicular direction and a plurality of catch mechanisms arranged circumferentially around the edge of the disc. A plurality of filaments are temporarily affixed to the mandrel, each filament extending from the mandrel toward the edge of the disc and engaging the edge of the disc at a discrete point of engagement. The plurality of catch mechanisms are attached to actuators adapted to move the catch mechanisms in a generally radial direction relative to the edge of the disc to allow the catch mechanism to engage a subset of the filaments and move the engaged filaments beyond the circumferential edge of the disc.
