A fluid sensor device can include a housing having an inlet and an outlet. The housing can have a fluid reservoir, a sensing assembly, a plunger, a valve, and a plurality of channels. The fluid sensor module can be used to sense constituents in a sample fluid (e.g. patient's blood or dialysate) during a treatment process, such as kidney dialysis procedures. The fluid sensor module can be connected in-line to a medical device to sense the sample fluid.

A connector includes a plug and a socket. The plug defines a channel extending between a plug inlet defined by the plug and a plug outlet defined by the plug, where the plug inlet is configured to mechanically and fluidically engage a first conduit. The socket includes a socket body defining a socket well and a socket membrane. The socket is configured to mechanically and fluidically engage a second conduit, and the plug is configured to insert into the socket well to mechanically mate with the socket. The socket membrane is positioned within the socket well and is biased to a closed position in which the socket membrane blocks fluid flow through the socket well. When the plug is inserted into the socket well, the socket membrane is configured to open to enable fluid flow through the socket well.

System and methods are provided for treating a patient that include a delivery device sized for introduction into a target site within a patient's body, a source of one or more therapeutic and/or diagnostic agents coupled to the delivery device, and a tubular member sized for introduction into the patient's vasculature to isolate the thoracic duct. Once the thoracic duct is isolated, fluid may be removed from the thoracic duct, e.g., to prevent the agents that transit from the target site into the thoracic duct from entering the patient's vasculature, and/or to modulate flow through the thoracic duct to modulate concentration and/or resident time of the agents at the target site. The one or more agents may include particles sized for preferential transit into the lymphatic system.

A device for establishing venous inflow to a blood reservoir of an extracorporeal blood circulation system includes a restricting unit for restricting a venous inflow line and a vacuum unit for supplying vacuum to the blood reservoir. The device includes a control unit that, upon setting the desired venous flow rate, automatically supplies a first actuating signal to the restricting unit for restricting venous inflow to the blood reservoir and supplies a second actuating signal to the vacuum unit for establishing a degree of vacuum within the blood reservoir, so as to achieve the set venous flow rate. The device includes a venous flow sensor.

A blood purification device includes a blood circuit for extracorporeally circulating blood of a patient; a liquid supply circuit for supplying a supply liquid to the blood circuit or to a blood purifier provided on the blood circuit and a waste liquid circuit for discharging the waste liquid from the blood purifier. Each of the blood circuit, the liquid supply circuit and the waste liquid circuit comprises a flexible tube. The blood purification device comprises a tube identification unit that performs a tube identification process for identifying a tube used for the blood circuit, the liquid supply circuit or the waste liquid circuit or determining whether or not there is an abnormality in the tube, based on an amount of liquid sent from a peristaltic pump provided on the blood circuit, the liquid supply circuit or the waste liquid circuit, or pressure fluctuation in the circuit, caused when driving the pump for a predetermined time.

The present disclosure relates to a disposable, which comprises a fluid line and a connector having a connector lumen, for fluidically connecting the fluid line to a first lumen of a first fluid guide of a port, which further comprises a second lumen. It further relates to a system with a disposable according to the present disclosure and with a port for establishing a fluid communication between at least one fluid line of the treatment apparatus, which fluid line is assigned to the interior of a blood treatment apparatus, and a connector of a fluid line of a disposable, which fluid line is assigned to the exterior of the treatment apparatus.

System and methods are provided for harvesting one or more organs, e.g., a lung from a donor body. In one embodiment, a distal end of a tubular member is introduced into the donor body's vasculature via a percutaneous access site, and the tubular member is manipulated until the distal end of the tubular member is disposed within the thoracic duct. Fluid is removed from the thoracic duct through the tubular member to a location exterior to the patient's body, and one or more organs are removed from the donor body. Optionally, one or more parameters within the thoracic duct or other parameters of the donor body may be monitored and fluid removal may be adjusted to reduce fluid accumulation within the one or more organs.

Disclosed is a hemofiltration device, system and method for rapid solute removal from a patient's blood. The device, and method employ a hemofiltration assembly for a high blood flow extracorporeal circuit, such as an ECMO circuit, configured to achieve high-efficiency, high-flux convective solute clearance, and optionally diffusive solute clearance, and include one or more hemofilters having greater filter medium surface area in a circuit having greater flow rates than previously implemented RRT modalities, and may offer rapid clearance of toxins, including those not currently dialyzable (e.g., those with high volumes of distribution).

The present disclosure provides for a cannula and balloon system for extracorporeal membrane oxygenation. The system may comprise one or more cannula, one or more insertion mechanism, and one or more balloon cuff. The method may comprise venous-venous or venous-arterial insertion into one or more blood vessels or chambers of the heart. The balloon cuff may allow fluid flow to avoid oxygenated blood restriction to a region of the body for the cannula insertion duration. One or both the balloon cuff and dual cannula may prevent occlusion, recirculation, and mixing of oxygenated and deoxygenated blood. When there is a dual cannula, the cannula may comprise a reinfusion cannula and a drainage cannula. A reinfusion cannula may bypass one or more chambers of the heart. When the system comprises more than one cannula, the cannulae may be joined via a cannula connection mechanism.

An attaching member attachable to a blood purification apparatus including a peristaltic pump, the attaching member holding a pump tube to be squeezed in a predetermined direction by the peristaltic pump for liquid delivery. The attaching member includes a body attachable to a predetermined position of the blood purification apparatus, and a holding portion attached to the body and that holds the pump tube. The holding portion holds the pump tube such that the pump tube is inclined in a direction in which the pump tube is attached to the peristaltic pump.
