  • Publication number: 20200108190
    Abstract: The present disclosure provides an apical connector for use in a heart wall. The apical connector may include a port defining an aperture therethrough, an anchoring device extending distally from the port and configured for advancing at least partially through the heart wall, and a cannula configured for advancing through the aperture of the port and at least partially through the heart wall. The cannula may include a locking tab configured to engage the port and lock the cannula with respect to the port.
    Type: Application

  • Patent number: 9421315
    Abstract: An compact hydraulic manifold for transporting shear sensitive fluids is provided. A channel network can include a trunk and branch architecture coupled to a bifurcation architecture. Features such as tapered channel walls, curvatures and angles of channels, and zones of low fluid pressure can be used to reduce the size while maintaining wall shear rates within a narrow range. A hydraulic manifold can be coupled to a series of microfluidic layers to construct a compact microfluidic device.

  • Patent number: 8388892
    Abstract: An in-line loss-on-ignition measurement system includes an on-site extractor subsystem configured to collect fuel or a combustion by-product from a hydrocarbon fuel burning plant. An on-site analyzer is configured to receive the collected matter from the extractor subsystem and configured to weigh the collected matter, burn the collected matter, and weight the collected matter again. A controller is responsive to the analyzer and is configured to determine the loss-on-ignition data for the plant based on the weight of the collected matter before and after it is burned in the analyzer.

  • Publication number: 20100198408
    Abstract: An in-line loss-on-ignition measurement system featuring an extractor configured to collect fuel or a combustion by-product from a hydrocarbon fuel burning plant, an on-site analyzer configured to receive the collected matter and determine loss-on-ignition data for the plant, a transfer mechanism configured to transfer the collected matter from the extractor to the analyzer, and a controller for displaying the loss-on-ignition data and/or for automatically adjusting one or more parameters associated with the plant.
