Tubular bundles are potted in a housing, such as in an oxygenator or a pheresis unit. Spacer material is placed into the housing to cover the first ends of the tubular elements. A layer of potting material is placed into the housing covering the spacer material, and then solidified in place to seal between each of the tubular elements and the housing. The spacer material is then removed from the housing to expose the first ends of the tubular elements. In the oxygenator, at least some of the tubes are gas exchange tubes having an interior lumen and a tube wall which is permeable for oxygen and carbon dioxide flow through the tube wall. The potting separates the housing into manifold chambers communicating with the interior of the tubes and a blood flow chamber sealed from the manifold chambers. Blood flows over the exterior surface of the tubes. Other tubes may be heat transfer tubes, such as for carrying a heat transfer fluid to control the temperature of the blood. Multiple pottings may be performed to provide separate sealed manifold chambers for each set of tubes.
