Abstract:
A multi-layer wound-fiber blood oxygenator, comprising:a) a core having an axis; b) a first group of wound-fiber layers, including i) at least one layer of hollow gas-exchange fibers wound around said core at an acute angle relative said axis, and ii) at least one layer of hollow gas-exchange fibers wound around said core at an angle of at least 90Â° relative said axis; c) a second group of wound-fiber layers, including i) at least one layer of hollow gas-exchange fibers wound around said core at an acute angle relative said axis, and ii)at least one layer of hollow gas-exchange fibers wound around said core at an angle of at least 90Â° relative said axis; and d) a planar, apertured mat positioned around said core between said first and second groups of layers, the mat consisting essentially of spaced coplanar plastic ribs intersecting each other to define apertures therebetween.
