摘要： A blood pump (1) comprises a pump casing (2) having a blood flow inlet (5) and a blood flow outlet (6) connected by a passage (7), and an impeller (3) arranged in said pump casing (2) so as to be rotatable about an axis of rotation (9). The impeller (3) is provided with blades (4) sized and shaped for conveying blood along the passage (7) from the blood flow inlet (5) to the blood flow outlet (6), the impeller (3) being rotatably supported in the pump casing (2) by at least one contact-type bearing (20) comprising a bearing surface of the impeller (3) facing a bearing surface of the pump casing (2). At least one wash out channel (30) extends through the impeller (3) and is in fluid connection with the passage (7) via a first opening (34) and with the bearing (20) via a second opening (35). The wash out channel (30) is operatively associated with a secondary pump for pumping blood through the wash out channel (30) towards the bearing (20), wherein the secondary pump is formed at least partially by said at least one wash out channel (30) extending through the impeller (3) along a direction having at least one tangential directional component.

摘要： A blood pump (1) for supporting a patient's heart comprises a flow cannula (4) having a distal end (10) and a proximal end (11) opposite the distal end (10), wherein the distal end (10) of the flow cannula (4) is configured to be connected to the patient's heart or a blood vessel in order to establish a fluid communication between the blood pump (1) and the patient's heart and blood vessel, respectively. The flow cannula (4) comprises a distal portion (5) having said distal end (10) and a proximal portion (6) having said proximal end (11). The flow cannula (4) further comprises an intermediate portion (7) attached to the distal portion (5) and the proximal portion (6), wherein the intermediate portion (7) allows clamping and twisting thereof with a lower force than the distal portion (5) and the proximal portion (6). At least a portion of the intermediate portion (7) either alone or in combination with the distal portion (5) is adapted to be permanently attached to the patient's heart or a blood vessel.

摘要： A sheath (10) for producing a fully sealed access to the interior of a vessel of an animal or human body comprises a base sheath (20) having a tubular body defining a pass-through channel (22). The base sheath (20) is adapted to be inserted into the vessel through a vessel aperture. A wall of the tubular body of the base sheath has a through channel (27). This channel extends in the wall from the distal end (20a) towards the proximal end (20b). The channel (27) can be present separately from the pass-through channel (22) of the base sheath or can form a sideways extension of the pass-through channel (22), at least at the distal end.. Such through channel (27) is adapted to conduct blood from the vessel to the proximal end of the sheath when the sheath has been inserted into a vessel.

摘要： In a blood pump system comprising a blood pump (50) and an intravascular flow cannula (53), a pressure sensor (30) is arranged within the flow cannula and, with respect to the flow cannula's longitudinal axis (1), at a level of the blood flow through opening (54) or bordering the blood flow through opening (54). By this arrangement, the pressure sensor (30) can be used to safely detect with great accuracy both the pressure outside the flow cannula (53) and the fact whether a blood vessel wall is sucked against the blood flow through opening (54).

摘要： A control device (100) for controlling the rotational speed ( n VAD (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.
