A medical device includes a constant-flow pump configured to pump a fluid through a fluid conduit and a rotary valve fluidically connected to the pump. The rotary valve includes at least one rotatable valve member configured to be operatively connected to and rotate relative to the fluid conduit. The rotatable valve member includes at least one aperture. The rotatable valve member is capable of being positioned in a plurality of positions relative to the conduit. The position of the at least one first aperture of the rotatable valve member controls fluid flow through the rotary valve, and thereby through the conduit.

The invention relates to an apparatus for extracorporeal blood treatment, comprising a blood treatment unit 1 that comprises at least one compartment 3. The invention further relates to an apparatus 15A, 15B for collecting blood clots for a blood line 5, 7 for supplying blood to or removing blood from a blood treatment unit 1 of an extracorporeal blood treatment apparatus, and to a method for determining a hemodynamic parameter during extracorporeal blood treatment using an extracorporeal blood treatment apparatus. In order to determine the hemodynamic parameter, the conveying direction of the blood pump 10 is reversed from a “normal” blood flow to a “reversed” blood flow. It has been found in practice that, in the event of a reversal in the conveying direction of the blood pump in order to carry out a measurement for determining a hemodynamic parameter, there is a risk of blood clots reaching the patients, although the dialyser traps blood clots. The apparatus according to the invention provides an apparatus 15A for catching blood clots, at least in the blood line of the extracorporeal blood circuit I that leads to the blood treatment unit 1 during a “normal blood flow”. The blood treatment unit traps blood clots during blood treatment having a “normal” blood flow. In the case of a “reversed” blood flow, the apparatus for catching blood clots in the blood line that leads to the blood treatment unit 1 during a “normal blood flow” traps blood clots that may have previously accumulated at the inlet of the blood treatment unit.

Intravascular blood pumps and methods of use. The blood pump include a pump portion that includes a collapsible blood conduit defining a blood flow lumen between an inflow and an outflow. The pump portion includes a distal collapsible impeller axially spaced from a proximal collapsible impeller, at least a portion of each of the distal and proximal collapsible impellers disposed between the inflow and the outflow.

Described are embodiments that include methods and devices for separating components from multi-component fluids. Embodiments may involve use of separation vessels and movement of components into and out of separation vessels through ports. Embodiments may involve the separation of plasma from whole blood. Also described are embodiments that include methods and devices for positioning portions, e.g., loops, of disposables in medical devices. Embodiments may involve use of surfaces for automatically guiding loops to position them into a predetermined position.

The specification discloses a portable dialysis machine having a detachable controller unit and base unit with an improved reservoir heating system. The controller unit includes a door having an interior face, a housing with a panel, where the housing and panel define a recessed region configured to receive the interior face of the door, and a manifold receiver fixedly attached to the panel. The base unit has a reservoir with an internal pan and external pan, separated by a space that holds a heating element. The heating element is electrically coupled to electrical contacts attached to the external surface of the external pan.

The present disclosure provides systems and methods for controlling gas-enrichment, e.g., oxygen-enrichment, therapy. One or more sensors and/or one or more imaging systems may be used to measure or determine one or more physiological parameters of the patient. Feedback regarding one or more physiological parameters or microvascular resistance may be provided for titrating or controlling the gas-enrichment therapy.

A remote service is implemented to automatically aggregate data across hemodialysis patients and determine updated treatment options for patients to increase well-being and optimize performance of the hemodialysis machines. Patients or caregivers operating a hemodialysis machine or a local or remote user computing device associated with the hemodialysis machine can provide feedback regarding the patient's well-being to the remote service. The feedback can be provided at any of one or more times pre-treatment, during treatment, or post-treatment. Furthermore, the hemodialysis machine can be configured with one or more sensors that transmit data pertaining to device state of the hemodialysis machine, such as information about blood, dialysate used, saline solution, pump pressure, air trap and air detector, hemodialysis machine information (e.g., make and model), etc.

Systems, methods, and devices are provided for the treatment of edema. In one aspect a method for implanting an indwelling catheter within a vein of a patient is provided. The catheter can extend from a position upstream of at least one outflow port of a duct of the lymph system to a terminal position downstream of the at least one outflow port. In use, a first restriction can be created within the vein proximal to a distal region of the catheter. The first restriction can define a localized low pressure zone distal of the restriction and within a portion of the vein housing the catheter. The low pressure zone can be adjacent to the at least one outflow port to enable fluid to pass from the at least one lymph duct outflow port into the vein.
