Systems and methods are configured for accessing and treating carotid arterial vasculature and establishing retrograde blood flow during performance of carotid artery stenting and other procedures.

The present disclosure relates to an addition line for adding an infusion solution to a fluid, which flows in an extracorporeal blood circuit, wherein the addition line comprises a pressure release valve or a check valve. It further relates to an extracorporeal blood circuit, a blood treatment apparatus and a method using the addition line.

A blood treatment device includes an extracorporeal blood circuit, a dialyzer and a dialysis fluid circuit. The extracorporeal blood circuit and the dialysis fluid circuit are separated from each other by a membrane provided in the dialyzer, by which blood can be filtered. At least one substitution solution pump supplies a substitution solution to the extracorporeal blood circuit before and/or after the dialyzer. A control unit calculates a difference or a backlog between an ideal target volume and an actually controlled volume of the supplied substitution solution, and temporarily increases a controlled flow rate of the substitution solution pump under corresponding controlling thereof by a predetermined, fixed percentage which is less than or equal to 5%, until the difference or the backlog between the actually controlled volume and the ideal target volume no longer exists, i.e. the actually controlled volume corresponds to the ideal target volume.

A multi-purpose cap adapted to fit onto fluid ports of different sizes and configurations of medical devices used for purifying or concentrating biological samples, wherein the cap is adapted to press fit onto diverse fluid ports on dialyzers and other blood treatment devices.

A tubing set for a blood processing system includes a first connector, a first tube, and a second tube. The first connector is configured to connect to a separation device within the blood processing system, and has a first inlet configured to be fluidly connected to an outlet of the separation device. The first connector also has an outlet and a second inlet. The first tube fluidly connects to the outlet and fluidly connects the separation device and a blood component storage container. The second tube is fluidly connected to the second inlet and fluidly connects the separation device and a saline storage container. The second tube may include a second connector that connects to the saline storage container.

This disclosure relates to dialysis systems and methods. In some implementations, a dialysis system includes a dialysis machine with a fluid line and a drain line, a blood line set configured to be connected to the dialysis machine, and a drain apparatus coupled to the dialysis machine. The drain apparatus includes a chamber configured to receive an end of a patient line of the blood line set, an inlet line, an outlet line, and a valve. The inlet line has a first end configured to be coupled to the chamber and a second end configured to be coupled to the fluid line of the dialysis machine. The outlet line has a first end configured to be coupled to the chamber and a second end configured to be coupled to the drain line of the dialysis machine. The valve is configured to control flow of fluid through the outlet line.

The present disclosure relates to a port for establishing a fluid communication between at least one fluid line of the medical treatment apparatus, which fluid line is assigned to the interior of a medical treatment apparatus, and a connector of a fluid line of a fluid-guiding disposable, which fluid line is assigned to the exterior of the medical treatment apparatus, wherein the port includes at least a first fluid guide and a second fluid guide. The first fluid guide has at least a first lumen and a first end-side opening, which is provided for receiving and/or guiding a first, medical fluid and for establishing the fluid communication with the connector. The second fluid guide has at least a second lumen and a second end-side opening. The first end-side opening of the first fluid guide is arranged, at least in sections, in the second lumen of the second fluid guide.

A drain cassette for a dialysis unit has a fluid channel between venous and arterial connection ports, and a valve may controllably open and close fluid communication between a drain outlet port and the venous connection port or the arterial connection port. A blood circuit assembly and drain cassette may be removable from the dialysis unit, e.g., by hand and without the use of tools. A blood circuit assembly may include a single, unitary member that defines portions of a pair of blood pumps, control valves, channels to accurately position flexible tubing for an occluder, an air trap support, and/or other portions of the assembly. A blood circuit assembly engagement device may assist with retaining a blood circuit assembly on the dialysis unit, and/or with removal of the assembly. An actuator may operate a retainer element and an ejector element that interact with the assembly.

A renal failure therapy system (10) includes a dialyzer (102); a blood circuit (100) in fluid communication with the dialyzer (102); a dialysis fluid circuit (30) in fluid communication with the dialyzer (102); a housing supporting the dialyzer (102), the blood circuit (100) and the dialysis fluid circuit (30); and at least one electrical socket (170) held by the housing, the electrical socket (170) providing a voltage output dedicated to a particular voltage type of external electrical device (200) for powering or charging the external electrical device (200), the at least one electrical socket (170) including electrical insulation for protecting a patient while powering the external electrical device (200).

A multi-purpose cap adapted to fit onto fluid ports of different sizes and configurations of medical devices used for purifying or concentrating biological samples, wherein the cap is adapted to press fit onto diverse fluid ports on dialyzers and other blood treatment devices.
