Abstract
A method and device is described for direct removal of heparin from whole blood during extracorporeal therapy. In clinical situations where the blood is heparinized to prevent clotting in the extracorporeal circuit containing e.g., a hemodialysis cartridge or a heart-lung machine, it would be desirable to eliminate the systemic heparinization of the patients. The extracorporeal circuit contains a device having antithrombin III immobilized and inserted between the outlet port of the primary extracorporeal device, such as the hemodialysis cartridge or heart-lung machine and the patient. When the heparinized blood comes in contact with the immobilized antithrombin III, heparin is removed and the reperfused blood is substantially free of heparin. The advantage of the system lies in the fact that heparin is removed from the blood rather than neutralized. This helps overcome the adverse reactions and side effects associated with the use of heparin anticoagulation.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
