Devices for potting a filter for blood processing
First Claim
1. A device for potting a filter, comprising:
- a housing having a first end, a second end, an outer surface, an inner surface, a hollow lumen, a first region near the first end, a second region near the second end, a first hole in the first region communicating between the outer surface of the housing and the hollow lumen, and a second hole in the second region communicating between the outer surface of the housing and the hollow lumen; and
a ridge on the outer surface of the housing that extends around the first hole to a point closer the first end of the housing and extends around the second hole to a point closer the second end of the housing, the ridge defining a trough having a continuous access defined by said ridge, said ridge having an edge adapted to seal against a separate cap such that during filter manufacturing, the housing and cap are rotated about an axis that bisects the housing and is perpendicular to an axis of the lumen, a flowable material is placed on the outer surface of the housing approximately halfway between the first hole and the second hole, a portion of the flowable material flows toward the first hole, is retained by the ridge and said separate cap, and passes through the first hole, and a portion of the flowable material flows toward the second hole, is retained by the ridge and said separate cap, and passes through the second hole.

Abstract
A device for potting a filter is described. The device comprises a housing having a first hole in the first region communicating between the surface and the lumen, and a second hole in the second region communicating between the surface and the lumen. A ridge extends around the first hole and the second hole to define a trough for receipt of a flowable potting material. During the manufacture of the filter assembly, the housing is rotated about an axis that bisects the housing and is perpendicular to an axis of the lumen, a flowable material is placed on the surface of the housing, a portion of the flowable material flows toward the first hole, is retained by the ridge, and passes through the first hole, and a portion of the flowable material flows toward the second hole, is retained by the ridge, and passes through the second hole.

8. A device for potting a filter, comprising:
- a housing having a first end, a second end, an outer surface, an inner surface, a hollow lumen, a first region near the first end, a second region near the second end, a first hole in the first region communicating between the outer surface of the housing and the hollow lumen, and a second hole in the second region communicating between the outer surface of the housing and the hollow lumen; and
a ridge on the outer surface of the housing that extends around the first hole to a point closer the first end of the housing and extends around the second hole to a point closer the second end of the housing, wherein, during filter manufacturing, the housing is rotated about an axis that bisects the housing and is perpendicular to an axis of the lumen, a flowable material is placed on the outer surface of the housing approximately halfway between the first hole and the second hole, a portion of the flowable material flows toward the first hole, is retained by the ridge, and passes through the first hole, and a portion of the flowable material flows toward the second hole, is retained by the ridge, and passes through the second hole wherein the ridge is a generally diamond-shaped parallelogram.
- a housing having a first end, a second end, an outer surface, an inner surface, a hollow lumen, a first region near the first end, a second region near the second end, a first hole in the first region communicating between the outer surface of the housing and the hollow lumen, and a second hole in the second region communicating between the outer surface of the housing and the hollow lumen; and

11. A device for potting a filter, comprising:
-
a filter housing configured to hold filter membrane fibers extending along a length thereof between first and second ends of said filter housing;
said filter housing having at least one first opening at said first end and at least one second opening at said second end, said at least one first opening and said at least one second opening communicating with an interior of said filter housing with a flow guide for guiding the flow of potting material;
said flow guide having a ridge connected alone a length of said filter housing such that said flow guide has the shape of an open trough;
said flow guide being configured such that potting material flows toward said holes when said flow guide is temporarily covered to enclose it by a cap and when said filter housing and said cap are spun about an axis perpendicular to a longitudinal axis of said filter housing, whereby when filter fibers are held in said filter housing and potting material so caused to flow, the amount of potting material settling toward said first and second ends is maximized. - View Dependent Claims (12, 13, 14, 15, 16)

17. A device for potting a filter, comprising:
-
means for supporting filter fibers;
means for containing potting material at ends of said means for supporting;
means for guiding permanently attached to said means for supporting a fluid effective to seal said filter fibers when said fluid is hardened;
means for temporarily enclosing an open length of said means for guiding, said means for guiding including means for conveying said fluid toward said means for containing such that said fluid is distributed evenly between said ends when said means for supporting, said means for guiding, and said means for temporarily enclosing are spun about an axis of said means for supporting. - View Dependent Claims (18, 19, 20)

21. A device for potting a filter, comprising:
-
a generally cylindrical housing with a hollow lumen and a trough defined by a ridge running longitudinally along an axis of said housing;
said ridge extending from said generally cylindrical housing such that said trough is closed on all sides except for a trough opening facing away from said housing except for at least one opening near each end of said housing communicating an interior of said trough with an interior of said housing;
said ridge having an edge adapted to seal against a separate cap thereby defining an enclosure such that during filter manufacturing, when the housing and said separate cap are rotated about a spinning axis, which is perpendicular to said housing axis, with a flowable material placed in said trough, said separate cap keeps said flowing material from flowing over said ridge, thereby causing said flowing material to flow into said openings, retained by the ridge and separate cap. - View Dependent Claims (22, 23, 24, 25)

26. A device for potting a filter, comprising:
-
a housing configured to hold a filter bundle, said housing having an elongated shape with a longitudinal axis;
said housing having an elongated open trough on a side thereof, said trough having a longitudinal axis generally parallel to said housing longitudinal axis;
said housing having at least one port communicating an interior of said housing with an exterior thereof;
said open trough being defined by a ridge having an edge;
said edge being shaped to form a seal with a trough cap such that said open trough may be enclosed. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33)
