Abstract
An artificial kidney system comprises an artificial kidney forming container having an inlet blood port connectable with a patient's artery and an outlet blood port connectable with a patient's vein so that blood from the patient's artery can flow through the inlet port into the container, then through an inner space of the container and then through the outlet blood port into the patient's vein, the inner space of the container being filled with an adsorbent for removing harmful and toxic compounds from a stream of blood flowing in the inner space from the inlet blood port to the outlet blood port, the container being provided with a separate chamber formed inside the inner space and limited by a semi-permeable polymeric ultrafiltration-type membrane which allows water and dissolved small molecules to be transported from blood into the chamber, and suction element connectable with the separate chamber so that the water and the dissolved small molecules are transported from blood into the separate chamber and further outside of the container under the action of suction of the suction element.

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.
