Systems and methods are disclosed for performing online extracorporeal photopheresis in which the needs of a particular patient as to the fluid balance to be achieved and the time allotted to perform the procedure can be prioritized. Whole blood is removed from a patient and introduced through a processing set into a separation chamber to separate the desired cell population from the blood. The separated cell population is processed through the set which is associated with a treatment chamber where the cells are treated. Once treated, the cells are returned to the patient.

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.

A soft cassette includes a body including a flexible material and first and second component. The body defines first and second lumens and first and second chambers. The first lumen extends between first and second ends. The first chamber is in the first lumen such that fluid passing through the first lumen passes through the first chamber. The second lumen is fluidly connected to the first lumen at a first junction between the first end and the first chamber and a second junction between the second end and the first chamber such that fluid passing through the second lumen bypasses the first chamber. The second chamber is in the second lumen. The first component is on a first side of the second chamber and includes a first ferromagnetic metal or magnet. The second component is on a second side of the second chamber and includes a second ferromagnetic metal magnet.

A hemodiafiltration system with a disposable pumping unit is disclosed. An example system includes a medical fluid pump actuator, a medical fluid heater, a blood filter and a disposable unit. The example disposable unit includes a medical fluid cassette portion including a medical fluid cassette housing configured to be operatively connected to the medical fluid pump actuator to pump medical fluid through the medical fluid cassette portion when the medical fluid cassette portion is in fluid communication with a medical fluid source. The example medical fluid cassette portion is also configured to be placed in fluid communication with the blood filter and with an extracorporeal circuit communicating with the blood filter, the fluid communication enabling hemodiafiltration to be performed. The example disposable unit also includes a heater bag configured to be placed in operable communication with the medical fluid heater and in fluid communication with the medical fluid cassette portion.

Systems and methods for performing apheresis procedures, including photopheresis. The systems and methods utilize a disposable fluid circuit that can be converted from a double needle configuration to a single needle configuration and from a single needle configuration to a double needle configuration. A controller directs the action of system pumps to clear potentially stagnant blood residing in the fluid circuit, tracks system parameters and status before and after conversion, and verifies that the procedure may proceed in its new configuration.

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 embodiments relate to an aphaeretic biopsy system. The aphaeretic biopsy system can implement a dialysis-like process to obtain a bloodstream by a draw line, separate released tumor cells (RTCs) from the bloodstream, capture the RTCs in a reservoir for further analysis, and return the remaining portion of the bloodstream to the patient via a return line.

A dialysis machine has a dialyzer having a first balancing chamber and a second balancing chamber, of which each has at least two first and second balancing chamber halves separated from one another by a movable wall. Each first balancing chamber half has a respective first inflow and a respective first outflow, with the first inflows of the first balancing chamber halves being in fluid communication with a source of fresh dialysate. The first outflow of the first balancing chamber half is in fluid communication with a dialyzer inflow, and the second inflows of the second balancing chamber halves are in fluid communication with a dialyzer outflow. The second outflows of the second balancing chamber halves are in fluid communication with one another so that consumed dialyzate is transferrable from a second balancing chamber half of one balancing chamber to a second balancing chamber half of the other balancing chamber.
