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 suction device configured to simultaneously draw in fluid and expel fluid. The suction device may comprise a barrel defining a cavity and extending from a first end to a second end. A first fluid inlet may be adjacent the first end of the barrel and a second fluid inlet adjacent the second end of the barrel and a first fluid outlet may be adjacent the first end of the barrel and a second fluid outlet adjacent the second end of the barrel. A plunger may be slideably disposed within the cavity of the barrel with a handle assembly operably coupled thereto. A actuation of the handle assembly may be configured to move the plunger within the cavity between the first end and the second end of the barrel.

Apparatus and methods are described, including apparatus (20) for implanting in a heart of a human subject. The apparatus includes an interatrial anchor (22) shaped to define an opening (26) having a diameter of 4-8 mm, and a bag (24) in fluid communication with the opening of the anchor. The apparatus is shaped to fit within a right atrium of the heart of the subject, and has a capacity of between 4 and 20 cm3. Other applications are also described.

A disposable fluid pump is provided with a housing including first and second faces, with a sidewall extending between the first and second faces. The housing defines a chamber, with an inlet and an outlet in fluid communication with the chamber. An impeller is rotatably mounted within the chamber and includes a plurality of flexible vanes. Such a pump may be incorporated into a disposable fluid flow circuit that is adapted to be mounted on a durable hardware for processing a fluid. In such a fluid flow circuit, the fluid pump may be integrated into a cassette of the circuit or, alternatively, the inlet and outlet of the fluid pump may be directly connected to fluid flow conduits of the circuit.

A blood ultrafiltration system comprises a blood filter with first and second compartments separated by a semipermeable membrane. Blood input and blood output lines are connected in fluid communication with the first compartment. An effluent line is connected in fluid communication with the second compartment. A peristaltic pump is arranged for repeated engagement with first and second line segments. In a first arrangement, the first line segment is part of the blood input line or the blood output line and the second line segment is part of the effluent line. In a second arrangement, the first line segment is part of the blood input line and the second line segment is part of the blood output line. The system is operable, by the peristaltic pump, to pump blood through the blood filter and control the extraction of ultrafiltrate in the blood filter.

The invention relates to, amongst other things, a catheter device comprising a catheter (24) in which a rotating shaft (25) which is made at least partially from a magnetic material is arranged, and a separating device which contains an annular body (27) surrounding the rotating shaft and having a cavity containing a magnetic body (13′), the magnetic body being arranged downstream from a point at which the shaft (25) exits the catheter (24) which it surrounds with respect to the direction of flow of the fluid through the catheter.

The invention relates to a catheter device (100) comprising a catheter (68) for insertion into a living being and at least one lumen (69, 70, 74, 79) for guiding a fluid flow within a section of the catheter device, and comprising a valve for controlling a fluid flow, in particular through a catheter, having a valve control chamber (12, 12a), into which an inlet opening (1a) of an inlet channel (1) and an outlet opening (2a) of an outlet channel (2) open, and further having a closure element (5, 13, 17) which can be moved in the valve control chamber (12, 12a) in a controlled manner and which, in at least a first position (I), closes the outlet opening (2a), in at least a second position (II) closes the inlet opening (1a), and which, in at least a third position (III), keeps open a connecting channel between the inlet opening (1a) and the outlet opening (2a), a valve train (A, A′, B, B′, 3, 14, 18) being provided and optionally moving the closure element (5, 13, 17) to at least the first, second or third position, and the at least one lumen (68, 70, 74, 79) being fluidically connected to the inlet channel or the outlet channel.

A sensor device for sensing at least one functional value of a medical device is described herein. The sensor device includes a micro-electronic-mechanical system, an attachment device, and a communication interface. The micro-electronic-mechanical system senses (for example, determines or detects) a functional value associated with a medical device. The attachment device attaches the sensor device to a medical device, a part of the body of a patient, or to the patient intracorporeally. The communication interface provides (for example, wirelessly transmits) at least one functional value to an external device.
