  • Publication number: 20230077402
    Abstract: A surgical device includes a substrate and a first coating that covers at least a portion of the substrate. The first coating includes a first polymer. The first coating having antibiotics dispersed in the first polymer such that the first polymer releases the antibiotics as the first polymer degrades. A second coating covers at least a portion of the first coating. The second coating includes a second polymer. The second polymer includes an alginate. The second coating has a hemostatic agent dispersed in the second polymer such that the second polymer releases the hemostatic agent as the second polymer degrades. The hemostatic agent is selected from epinephrine, tranexamic acid, chitosan and oxidized regenerated cellulose. In some embodiments, systems and methods are disclosed.

  • Patent number: 8439858
    Abstract: An arterial line blood filter for use in extracorporeal blood circuits during heart bypass surgery has, among other components, a housing with a cap portion, a base portion, and a generally cylindrical wall portion. The blood filter has a filter element disposed within the housing. An inlet is positioned at an upward angle with respect to the housing and includes an opening in the generally cylindrical wall portion in fluid communication with the inlet chamber. In some embodiments the position of the inlet limits the pressure drop and prime volume of the filter. According to one embodiment, the cap portion has an upwardly sloping inner surface and there is a vent in the cap portion. The inner surface of the cap portion can have a projection proximate the vent configured to limit immobilization of gaseous microemboli within the inlet chamber.
