ABSTRACT:
An arterial line blood filter for use in extracorporeal blood circuits during heart bypass surgery. The blood filter includes a housing having a cap portion, a base portion and a generally cylindrical wall portion. A filter element is disposed within the housing and divides the housing into an inlet chamber in flow communication with a blood inlet and an outlet chamber in flow communication with a blood outlet. The filter element may include a plurality of concentric annular pleats, the length of which may be substantially equal to the length of the wall portion, the pleats being supported by a support element. In another embodiment the inner surface of the cap defines an inwardly spiral blood flow path which slopes upward and provides an effective means of distributing blood over the filter element.
