ABSTRACT:
A filter for an extracorporeal blood circuit including: a bundle of hollow fibers having an end section encased in a potting material, wherein the end section further comprises a stem of fibers and potting material and an annular disk of the potting material extending radially outward from the stem, wherein the annular disk of the potting material is substantially wider than the stem, the stem protrudes from the disk and the stem includes a side surface extending along a length of the stem; an end surface of the stem substantially perpendicular to the length of the stem and including open ends of the fibers distributed throughout the end surface including open ends proximate to a perimeter of the end surface; a filter housing through which extends the bundle, the filter housing comprising a tubular section and a first end section and a second end section at opposite ends of the tubular section, wherein the annular disk is seated in the first end section and the stem is narrower than the tubular section along the length of the stem; a filter header cap mounted on the first end section of the filter housing, wherein the filter header cap includes an inlet connectable to a blood line and an open end, the filter header cap including a cap side surface abutting the stem side surface, and the second end section connectable to a blood line.
