A medical device is adapted for use in assisting with mechanical thrombectomy. The medical device may include a housing that is adapted to be held within a user's hand and a pump that is secured within the housing. A fluid inlet is adapted to receive fluid that is pulled towards the pump and is fluidly coupled with the pump. A fluid outlet is adapted to expel fluid away from the pump and is fluidly coupled with the pump. As the pump is operated by the user, fluid is alternatively pulled into the fluid inlet and expelled through the fluid outlet. In some cases, the fluid may be blood or other bodily fluids.

A dialysis system may include a blood circuit, a cassette, a subsystem having a processor, a sensor, and a blood pumping mechanism, a housing in which the subsystem is arranged, a movable support arranged in the housing and configured to hold the sensor and/or the blood pumping mechanism of the subsystem, a cassette holder configured to removably receive the cassette, and a loading system. The loading system may be configured to move the movable support, e.g. by an axial movement, to a first position and to a second position relatively to the housing while the cassette holder is fixedly arranged in the housing. The loading system may have an electric motor controlled by the processor, a drive assembly coupled to the electric motor, and a guiding assembly configured to cooperate with the drive assembly.

A primer may be used with IV catheter systems. The primer may be positioned along the tubing of an extension set such that the primer divides the IV catheter system into a downstream portion and an upstream portion. The primer may vent air from both the upstream and downstream portions to allow blood to flow up to the primer while also allowing priming solution to flow down to the primer. As a result, the catheter may be inserted into the patient's vasculature without first priming the catheter. Once the air has been vented from the upstream and downstream portions of the IV catheter system, the primer may be actuated to open a fluid pathway through the primer. With the fluid pathway opened, the priming solution may commence flowing towards the patient's vasculature thereby flushing the blood from the IV catheter system.

A blood processing apparatus includes an optional heat exchanger and a gas exchanger disposed within a housing. In some instances, the gas exchanger can include a screen filter spirally wound into the gas exchanger such that blood passing through the gas exchanger passes through the screen filter and is filtered by the spirally wound screen filter a plurality of times.

A system for regulating blood flow in extracorporeal circulation, and including a blood reservoir to receive blood from a patient, an oxygenator to condition the blood, a centrifugal pump to pump the blood from the blood reservoir to the oxygenator and back to the patient, an electronic remote clamp to regulate flow of the blood, and a controller to operate in a flow control mode and a speed control mode. The controller includes an operational element to set a blood flow value in the flow control mode and to set a speed of the centrifugal pump in the speed control mode. The controller to automatically switch between the flow control mode and the speed control mode in response to one or more trigger conditions and to automatically switch between the speed control mode and the flow control mode in response to opening the electronic remote clamp.

A blood treatment device for extracorporeal blood treatment and a method for monitoring the fill level of blood with the blood treatment device. The device includes at least one blood conducting system and at least one chamber container for separating bubbles from the blood to be treated. The device further includes a blood pumping device designed to pump the blood and generate pressure pulses with a predefined frequency in the blood conducting system. The blood treatment device additionally has at least one pressure detection sensor for capturing the pressure pulse introduced by the blood pumping device and a data processing unit designed to derive a fill level parameter from the pressure pulse captured and to modify the state of an information signal as a function of the fill level parameter. At least one alarm device is activated as a function of the state of the information signal.

A processor of a medical device configured to communicate with a remote server can be programmed to protect the medical device from exposure to unauthorized or malicious software. A system or method to implement this form of protection can include, for example, at least one processor on the medical device, a control software module that controls the operation of the medical device and is executable on the processor, a data management module that manages data flow to and from the control software module from sources external to the medical device, and an agent module that has access to a limited number of designated memory locations in the medical device. In addition, a hemodialysis apparatus can be configured to operate in conjunction with an apparatus for providing purified water from a source such as a municipal water supply or a well. A system for controlling delivery of purified water to the hemodialysis apparatus can comprise a therapy controller of the hemodialysis apparatus configured to communicate with a controller of a water purification device, and a user interface controller of the hemodialysis apparatus configured to communicate with the therapy controller, and to send data to and receive data from a user interface.

A drip chamber assembly that functions irrespective of its orientation and in the presence of increased internal pressure is provided.

An exhaust gas flow control system for an oxygenator of an extracorporeal ventilation system connected to an oxygenation gas supply line and to an exhaust line for removal of exhaust gas comprises a flow control path, a pressure control path, an exhaust flow regulator responsive to the controller, and an exhaust gas pressure regulator responsive to a controller configured to maintain a pre-determined pressure level in the exhaust line. This provides a better degree of control over the pressure across the oxygenator from oxygenation gas inlet to exhaust.

A device for conditioning blood including a heat exchanger module including a heat exchanger fiber layer including heat exchanger fibers to receive a heat exchanger fluid and exchange heat with the blood, a gaseous micro-emboli removal module including a micro-porous fiber layer including micro-porous fibers to receive atmospheric or sub-atmospheric pressures such that at least some gaseous micro-emboli are drawn from the blood through the micro-porous fibers, a gas exchanger module including a gas exchanger fiber layer including gas exchanger fibers to receive a gas mixture and exchange gas with the blood, and a potting material body that embeds the heat exchanger fibers, the micro-porous fibers, and the gas exchanger fibers and defines a blood compartment that extends through the heat exchanger module, the gaseous micro-emboli removal module, and the gas exchanger module.
