  • Patent number: 8790285
    Abstract: A chest compressor includes a piston (14) that moves in downward and upward strokes, with the piston undergoing a smooth reversal at the bottom of the downward stroke. A compression spring such as a wave spring (60), is positioned to engage the piston only near the end of its downward stroke, to smoothly reverse the piston motion, limit downward force on the patient at the end of the stroke, and avoid a downward pulse due to the momentum of the downwardly-moving piston. A stop (90, 92) is latchable in an inward position to allow reduction in the piston stroke by engaging an outward flange (56) on the piston before the piston has moved fully downward.

  • Patent number: 8790298
    Abstract: A system for moving particles suspended in a first fluid, and for infusing them into the stream of a second fluid, includes a catheter with a multi-lumen distal separator. The separator is formed with a plurality of parallel lumens, wherein each lumen has a predetermined diameter. Importantly, the diameter of each lumen is dimensioned to sequentially receive particles therethrough, to prevent the particles from flocculating before they enter the stream of the second fluid. A recollection chamber in fluid communication with the separator allows for reconsolidation of the fluid after leaving the separator and for minimizing the damage caused to the vessel when the fluid exits the catheter. An inflatable balloon, affixed to the outside of the catheter, can be provided to regulate flow of the second fluid and thereby facilitate entry of the particles into the stream of the second fluid and increase retention of particles in targeted tissue.

  • Patent number: 8790318
    Abstract: The invention concerns a flow regulator, made of a stack of 3 plates, respectively a top plate including a flexible membrane (1), a middle plate (2) with pillars and through holes and a bottom plate (3) with fluidic ports, micro channels and through holes (8,9,12). The principle is based on the deformation of the membrane due to the pressure of the liquid. The membrane goes in contact with the pillars of the middle plate, obstructing gradually the through holes of the pillars. The device is designed to keep the flow constant in a predefined range of pressure. The device is dedicated to ultra low flow rate up to 1 ml per day or below, typically for drug infusion. Plastic flow regulators comprise preferably several independent valves coupled in parallel. The membrane plate is therefore made of several flexible membranes obstructing gradually the flow by increasing the pressure. Stress limiters are used to avoid plastic deformation of the membrane.

    Abstract: The present invention provides for the harvesting of specific materials in multiple stages of filtration of bone graft materials from a Reamer-Irrigator-Aspirator (RIA) Device, specifics of interconnected stages, related filtration materials, and techniques. The harvesting process collects large material in a first stage, and other materials of a limited geometric size in at least a second stage of filtration. Such material captured in the second stage may contain plasma, cellular elements including stem cells as well as growth factors and other particulate matter of a specific geometrically limited size, using various filtration approaches including centrifugation in some embodiments. Further embodiments of the invention provide for an improved tubing interface and management approach to ease use in the operating room. Filtration materials may include collagen based filters and may allow direct implant of small scale and larger scale matter in specific portions within the collagen itself.

  • Patent number: 8790326
    Abstract: Wearable disposable absorbent articles such as disposable diapers, having elastically extensible fastening members (also sometimes known as fastening “ears”) with particular features, extending from a chassis or main portion of the articles, are disclosed. The fastening members may be highly extensible and have an overall geometry characterized by greater length nearer the chassis or main portion and lesser length nearer the distal end. Examples disclosed may have a fastener zone having a Stiffness of at least about 1,500 N/m, and shape and dimensional characteristics, that help avoid problems of buckling and/or flipping of edges of the fastening members, dishing of fastener components, and fastening member tearing, while the articles are applied and worn.
