摘要： An intravascular blood pump having a drive section (11), a catheter (14) fastened to the drive section proximally and a pump section (12) fastened to the drive section distally possesses an electric motor (21) whose motor shaft (25) is mounted in the drive section (11) with two radial sliding bearings (27, 31) and an axial sliding bearing (40). During operation, purge fluid is conveyed through the bearing gap of the axial sliding bearing (40) and farther through the radial sliding bearing (31) at the distal end of the drive section (11). The purge fluid is highly viscous, for example 20% glucose solution.

摘要： A blood pump system including a blood pump, an intravascular flow cannula, and a pressure sensor. The intravascular flow cannula is in flow communication with the blood pump and has a distal end portion distally from the blood pump and a proximal end portion closer to the blood pump. The intravascular flow cannula has at least one blood flow through opening at its distal end portion for blood to enter or exit the flow cannula. The blood flow through opening has a borderline surrounding the through opening. The pressure sensor is configured radially within the flow cannula and borders a proximal portion of the borderline.

摘要： This invention is directed to a corrosion-resistant permanent magnet, to a method for producing a corrosion-resistant permanent magnet, and to an intravascular blood pump comprising the magnet. The magnet is corrosion resistant due to a composite coating comprising a first layer structure and optionally a second layer structure on the first layer structure, each layer structure comprising an inorganic layer, a linker layer on the inorganic layer, and an organic layer formed from poly(2-chloro-p-xylylene) on the linker layer. The inorganic layers comprise aluminum and/or aluminum oxide.

摘要： An intravascular blood pump (1) comprises a ring seal (10) that is configured to assume a collapsed configuration and an expanded configuration and configured to contact and seal against an inner wall of the patient's blood vessel when inserted therein in the expanded configuration. A support member (12; 13) is disposed inside the ring seal (10) in order to support the ring seal (10) from the inside, wherein the support member (12; 13) is configured to collapse at least partially when a predetermined pressure difference between a proximal area and a distal area of the blood vessel acting on the ring seal (10) is exceeded.

摘要： The invention relates to an intercardiac pump device comprising a pump (11) whose distal end (13) is connected to a cannula (15) which is provided with a suction head (16) for sucking blood. Said strainer is provided with a non-sucking extension (20) for stabilising the position of said pump device in the heart and mechanically prolonging the cannula (15) without deteriorating hydraulic conditions. Said extension is also used in the form of a spacer in order to avoid that the suction head (16) adheres to a cardiac wall.

摘要： A control device (100) for controlling the rotational speed (nVAD(t)) of a non-pulsatile ventricular assist device, VAD, (50) uses an event-based within-a-beat control strategy, wherein the control device is configured to alter the rotational speed of the VAD within the cardiac cycle of the assisted heart and to synchronize the alteration of the rotational speed with the heartbeat by at least one sequence of trigger signals (σ(t)) that is related to at least one predetermined characteristic event in the cardiac cycle. Further, a VAD (50) for assistance of a heart comprises the control device (100) for controlling the VAD, wherein the VAD is preferably a non-pulsatile rotational, for example catheter-based, blood pump.

摘要： A system for providing vascular access in a patient's body may comprise at least one hemostatic valve (610) and at least one clamp (210) to be used with a vascular graft (110). The vascular graft (110) comprises a tubular body having a proximal end (110A) and a distal end (110B), the proximal end (110A) being configured to be attached to a vessel in a patient's body. The at least one valve (610) is configured to be attached to the distal end (110B) of the graft's tubular body and comprises a housing (616) including a flexible membrane (611) that allows a medical device (810) to be inserted through the membrane (611) into said vascular graft (110). The valve (610) further comprises an introducer sheath (615) configured to be inserted into the distal end (110B) of the graft's tubular body. The at least one clamp (210) is configured to be disposed around the graft's tubular body and has a first configuration that allows insertion of the valve's introducer sheath (615) into the distal end (110B) of the graft's tubular body and a second configuration that allows clamping of the graft (110) against the valve's introducer sheath (615), when inserted in the graft's tubular body.
