A filter apparatus for removing small molecule chemotherapy agents from blood is provided. The filter apparatus comprises a housing with an extraction media comprised of polymer coated carbon cores. Also provided are methods of treating a subject with cancer of an organ or region comprising administering a chemotherapeutic agent to the organ or region, collecting blood laded with chemotherapeutic agent from the isolated organ, filtering the blood laden with chemotherapeutic agent to reduce the chemotherapeutic agent in the blood and returning the blood to the subject.

Systems and methods for managing the pH of a dialysate fluid during hemodialysis therapy. The systems and methods adjust dialysate pH and buffer concentration to generate a predetermined total bicarbonate buffer concentration in a dialysate entering a dialyzer. The systems and methods generate a pH-modifying fluid and selectively add the pH modifying fluid to the dialysate in order to accurately control the total bicarbonate buffer concentration in the dialysate entering the dialyzer.

Circulating cell clusters found in subjects with cancer, autoimmune conditions, infections, or other diseases, can be trapped or disrupted by filtering them with an intra- or extracorporeal device and, in some cases, exposing them to a substance, such as enzyme, that reduces intercellular adhesion.

The present invention relates to an apparatus for an extracorporeal blood treatment having an extracorporeal blood circuit in which a dialyzer is arranged and having a dialyzate circuit, wherein the blood circuit is in fluid communication with a first chamber and the dialyzate circuit is in fluid communication with a second chamber of the dialyzer, and wherein the two chambers are separated from one another by a semipermeable membrane, with a dialyzate pump for a conveying of the dialysis solution being present in the dialyzate circuit, wherein the apparatus has a control unit that is configured to operate the apparatus in a first phase and in a second phase following the first phase, wherein the dialyzate pump is operated with a smaller flow rate in the first phase than in the second phase and/or wherein the dialyzate pump conveys a dialysis solution in the first phase that is of a higher concentration with respect to at least one component than in the second phase.

A crossflow filter includes a rigid cylindrical inner wall and a rigid cylindrical outer wall inner with an inelastic filter membrane positioned therebetween defining a retentate channel inside the filter membrane and a permeate channel outside the filter membrane. Further, the filter includes transition channels shaped and connected to the inner and outer walls to deliver a flow of fluid from an inlet port to the retentate channel and to capture flow flowing longitudinally along the cylindrical inner and outer walls from both the retentate and permeate channels to respective outlet ports.

An artificial kidney configured to automatically or semi-automatically perform priming, procedure running, purging, flushing, and procedure ending. The artificial kidney is wearable and can be used while ambulating, sitting, and lying down. The artificial kidney can be used at home as a supplement to standard intermittent hemodialysis therapy in the clinic. In an example, the artificial kidney can be configured to perform alert event detection, start a timer, and take steps to resolving the alert event. The steps can include automated steps and can include instructions to be manually performed by the user (or the patient). If the alert event is resolved within a set time, the artificial kidney can continue to perform procedure running. If the alert event is not resolved within the set time, the artificial kidney performs the procedure ending.
