  • Membrane apparatus with enhanced mass transfer, heat transfer and pumping capabilities via active mixing
    Publication number: 20040219061
    Abstract: A combination mass transfer and pump apparatus, which in a single step actively mixes a first mass and a second mass and simultaneously pumps one of the first mass and the second mass through the apparatus. The combination mass transfer and pump apparatus substantially comprises a housing and at least one distributor element having a plurality of selectively fluid-permeable membrane elements wherein the at least one distributor element is agitated within the second mass such that the first mass diffuses across the selectively fluid-permeable membrane elements, mixing with the second mass, and in the same step the second mass is pumped through the housing.
    Type: Application

  • Device and method of use for functional isolation of animal or human tissues
    Publication number: 20040030335
    Abstract: A method and apparatus for functionally occluding the lumen of the left atrial appendage (LAA) is provided. Access to the LAA is through an epicardial approach. The devices function to capture the LAA through various non-invasive means. After capturing the LAA with the devices and methods provided, a clamping device is preferably disposed about the base of the appendage. In certain embodiments, the appendage remains viable subsequent to the functional occlusion of the lumen.
