摘要： The present invention provides a spiral membrane element suitable for suppressing a decrease in a permeation rate (or a permeation flux) of a permeated fluid from a separation membrane. A spiral membrane element of the present invention includes: a central tube; a membrane leaf that has a separation membrane and a permeation spacer and is wound around the central tube; and a flow passage spacer that is connected to the permeation spacer and is wound around the central tube on a side closer to the central tube than the membrane leaf is. A pressure loss of the flow passage spacer measured by a predetermined test is smaller than a pressure loss of the permeation spacer.

摘要： Provided are a composite semipermeable membrane capable of enhancing adhesion between a separation functional layer provided with a coating layer and a protective tape while maintaining an effect of the coating layer to some extent, and a spiral membrane element using the composite semipermeable membrane.
A composite semipermeable membrane includes: a porous support; a separation functional layer formed on the porous support; and a coating layer provided on a surface of the separation functional layer, the coating layer having different surface roughnesses due to different adhesion amounts of a coating material depending on locations. The composite semipermeable membrane has a coating layer-side surface on which a glossy portion having a surface roughness Ra of 30 nm or less and a non-glossy portion having a surface roughness Ra of 50 nm or more are provided.

摘要： Devices and methods are provided for inducing ventricular growth in a single ventricle patient that include a plurality of anchors spaced apart from one another in an annular configuration; a plurality of springs with respective springs coupled to adjacent anchors around a perimeter of the annular configuration to bias the anchors to expand radially outwardly; and one or more elongate elements extending around the perimeter between the anchors to limit radial expansion of the anchors.

摘要： The disclosure relates to a membrane leaf packet, and a spiral membrane element including a plurality of such membrane leaf packets, including such elements exhibiting enhanced sanitary properties. Such membrane elements can be used for filtration, for example, in food-related fields, including filtering dairy, sugar and/or other liquid streams.
