An integrated on-line monitoring and thermostatic heating apparatus for a bioartificial liver device, the apparatus including a blood inlet, a blood pump, an arterial drip chamber, a bioreactor module, a venous drip chamber, and a blood reinfusion port which are connected in sequence. The bioreactor module includes a thermostatic water tank and a bioreactor disposed in the thermostatic water tank. The bioreactor includes a container, and a first partition and a second partition which are disposed in the container. The first partition and the second partition separate the container into three independent parts, that is, a plasma separator, an oxygenator, and a reactor. The plasma separator and the oxygenator are connected through an external connection pipe. The external connection pipe is equipped with a separation pump. The second partition includes a communication hole, and the reactor and the oxygenator are connected through the communication hole.

A bioartificial liver device including a bioreaction chamber having a plurality of semi-permeable membranes and a plurality of filter spaces each confined by two adjacent semi-permeable membranes; a plurality of liver cell perfusion ports each communicating with one of the filter spaces for introducing the liver cells into the filter spaces, and a positive peristaltic pump. In the device, the semi-permeable membranes are disposed substantially horizontal with respect to the ground, and the positive peristaltic pump is adapted to drive the plasma flow from the bottom wall of the device to the top wall. The device of the invention improves the cell loading and the area for substance exchange between the blood and the liver cells.

An apparatus for high-throughput rapid trapping and purifying of circulating tumor cells and a method for purifying circulating tumor cells, relating to the field of biotechnology. The apparatus for high-throughput rapid trapping of circulating tumor cells comprises: a filter module, the filter module comprises a filter, a filter membrane which is arranged inside the filter and sealed with an inner wall of the filter, and a negative pressure device; the negative pressure device is connected with an end of an outlet of the filter, and used for maintaining a negative pressure within the filter; when a negative pressure is maintained within the filter by the negative pressure device, the filter membrane is configured to trap circulating tumor cells, then stain and wash the trapped cells by using reagents which are automatically loaded by means of a reagent loading module. The apparatus may automatically control loading a sample liquid to the filter as well as the negative pressure device, such that the process in which the circulating tumor cells are trapped by using the filter membrane and then stained has the advantages of being highly automated and having a high throughput (which can be achieved by means of increasing the number of filters).

A combined bio-artificial liver support system, includes branch tubes that are connected in sequence: a blood input branch tube, an upstream tail end of which is set as a blood input end, a first plasma separation branch tube comprising at least a first plasma separator, a non-biological purification branch tube comprising at least a plasma perfusion device and a bilirubin adsorber, a biological purification branch tube comprising at least a hepatocyte culture cartridge assembly, and a plasma return branch tube, a downstream tail end of which is set as a blood output end.

The present disclosure relates to devices for the extracorporeal treatment of a patient having a complement factor related disease. The devices are adapted to remove said complement factors from the blood or blood plasma of a patient in need. The disclosure further relates to extracorporeal circuits comprising such devices and methods for the treatment of a patient suffering from a complement factor related disease.

Described are compositions and methods for treating liver disease, e.g., acute liver disease, using bone marrow-derived stem cells and bone marrow-derived stem cell conditioned media.

Described are devices and methods for use in connection with organ replacement or organ assist therapy in a patient.

This document provides bioartificial liver (BAL) devices. Methods for making and using BAL devices also are provided.

Methods and systems are provided for a stem cell organ device including an array of alternating stem cell channels and fluid channels. In one example, a method may include loading a stem cell channel with stem cells and flowing blood through a fluid channel in order to allow an exchange of molecules between the stem cells and the blood.

A bioreactor is provided which contains cells capable of producing cytokine inhibitors in response to cytokines, in a manner regulated by the local or systemic milieu of an individual patient and predicted by mechanistic computational simulations. The bioreactor transfers the cytokine inhibitors to a patient in need of control of the inflammation process as part of a disease or condition in the patient, such as sepsis, trauma, traumatic brain injury, or wound healing. Related methods also are provided.
