<p>An exchanger (100), and method for manufacturing are disclosed. In one embodiment, the exchanger crimps a hollow fiber bundle (112) along a length of a cylindrical case (108) in at least two radial positions. At least one crimp is between an inlet port (104), and an outlet port (120) of a blood conduit (156). The cylindrical case has two portions with different radii so that when the two portions are mated to enclose the hollow fiber bundle, crimping is achieved. In another embodiment, a method for making an exchanger includes filling a chamber, integral to the exchanger, with uncured potting material (124). The exchanger is spun to distribute the uncured potting material about open ends of an encasement. After curing, a portion of the potting material, and the hollow fiber bundle are trimmed. Preferably, the cured potting material includes an annular relief (168).</p> |
