摘要： A blood pump comprises a pump casing having a blood flow inlet and a blood flow outlet connected by a passage, and an impeller rotatable about an axis of rotation. A surface of the impeller faces a surface of the pump casing spaced from said surface of the impeller by a clearance, the clearance being in fluid connection with the passage at a clearance transition point. At least one wash out channel extends through the impeller and is in fluid connection with the passage via a first opening and with the clearance via a second opening. The first opening of the wash out channel is arranged in an area of the impeller that is under a higher pressure than the clearance transition point so as to cause a blood flow from the first opening through the wash out channel and the clearance to the clearance transition point.

摘要： A securing assembly for connecting a drive assembly to a driven assembly of a catheter pump includes a motor housing, a flow diverter housing, and a flow diverter positioned within the flow diverter housing, wherein one of the flow diverter or the flow diverter housing includes a securement device. The securing assembly also includes a cap coupled between the motor housing and the flow diverter housing. The cap includes a central opening and a locking recess extending circumferentially about the central opening. Insertion of the flow diverter into the central opening causes securement device to engage the locking recess.

摘要： Sensors for catheter pumps are disclosed herein. The catheter pump can include a catheter assembly comprising a catheter and a cannula coupled to a distal portion of the catheter. The cannula can have a proximal port for permitting the flow of blood therethrough. The catheter assembly can include a sensor to be disposed near the proximal port. A processing unit can be programmed to process a signal detected by the sensor. The processing unit can comprise a computer-readable set of rules to evaluate the signal to determine a position of the cannula relative to an aortic valve of a patient.

摘要： The invention relates to a micromotor (10), the stator of which contains a back iron jacket (18). Said back iron jacket consists of a continuous unslotted sleeve consisting of a metal alloy that contains ferritic iron as the main constituent, up to 30% chromium and preferably aluminium and yttrium oxide. Electric conductivity is reduced by the oxidation of the aluminium. The yttrium oxide performs the same function. The reduced electric conductivity suppresses eddy currents to a great extent. The back iron jacket (18) has a high magnetic conductivity with a small wall thickness, thus increasing the electrical output for a motor with a small diameter.

摘要： The subject matter of the present invention is a pump arrangement (1, 10, 20, 30, 40, 50), in particular for use in the body's own vessels, having a pump (11, 41, 51) and a sheath (12, 42, 52) receiving the pump, bounding a flow passage (S) and having a distal intake opening (13, 43, 53) and a proximal outflow opening (14, 29, 39, 44, 54) for producing a driving flow by means of the pump, wherein the pump is arranged in a first fluid-tight section (12a, 42a, 52a) having the distal intake opening and a second fluid-tight section (12b, 42b, 52b) includes the proximal outflow opening. In accordance with the invention, a further inlet opening (15) is present between the first section and the second section and is arranged between the intake opening and the outflow opening, with the first section and the second section being arranged with respect to one another such that the inlet opening opens into the flow proximal to the pump.
