Abstract: A blood pump for supporting a patient's heart includes a flow cannula having a distal portion including a distal end and a proximal portion including a proximal end opposite the distal end, the distal end of the flow cannula configured to be connected to the patient's heart or a blood vessel to establish fluid communication between the blood pump and the patient's heart and blood vessel, respectively. The flow cannula further includes an intermediate portion attached to the distal portion and the proximal portion, wherein the intermediate portion allows twisting thereof with a lower force than the distal portion and the proximal portion. The intermediate portion can be fully occluded by twisting it. At least a portion of the intermediate portion either alone or in combination with the distal portion is adapted to be permanently attached to the patient's heart or a blood vessel.

Abstract: A blood pump comprises a pump casing having a blood flow inlet and a blood flow outlet connected by a passage, and an impeller arranged in said pump casing so as to be rotatable about an axis of rotation. The impeller is provided with blades sized and shaped for conveying blood along the passage from the blood flow inlet to the blood flow outlet, and is rotatably supported in the pump casing by a first bearing at a first axial end of the impeller and a second bearing axially spaced apart from the first bearing. The first bearing comprises a projection extending along the axis of rotation and connected to one of the impeller and the pump casing and a cavity in the other one of the impeller and the pump casing, the projection comprising an enlarged portion that engages the cavity such that the first bearing and the second bearing are arranged to bear axial forces in the same axial direction.

Abstract: 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.

Abstract: 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.

Abstract: A blood pump comprises a pump section and a flow cannula. A proximal end portion of the flow cannula is connected to the pump section such that blood can enter the blood flow inlet, and a distal end portion of the flow cannula includes at least one blood flow-through opening for blood to enter the flow cannula. The distal end portion comprises an enlarged diameter portion, with at least a major portion of the blood flow-through opening being disposed in the enlarged diameter portion. The blood pump further comprises a sleeve overlapping the enlarged diameter portion. The sleeve has a structure that prevents its distal end from bending radially inwards into the blood flow-through openings.

Abstract: An introducer set (1) for providing vascular access in a patient's body comprises an Introducer sheath (10) and a dilator (20). The introducer sheath (10) has a tubular body (11) made of flexible material with a distal portion (12), a proximal portion (13) and an inner surface, the proximal portion (13) being configured to be inserted into a patient's vessel to allow a medical device (100) to be inserted through the introducer sheath (10) into the patient's vessel. The tubular body (11) of the introducer sheath has a wall thickness (d) of 0.3 mm or less. The dilator (20) has a body (21) with a proximal portion (23), a distal portion (22) and an outer surface, the dilator (20) being insertable into the introducer sheath (10) such that its proximal portion (23) extends proximally of the introducer sheath (10) when the dilator (20) is inserted in the introducer sheath (10). At least one of the dilator (20) and the introducer sheath (10) comprises a stiffening structure (25) imparting stiffness to the tubular body (11) of the introducer sheath (10), wherein said stiffening structure (25) can be released, removed or otherwise deactivated.

Abstract: 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.

Abstract: An introducer sheath for providing access in a patient's body comprises a tubular body with a distal portion and a proximal portion, the proximal portion being configured to be inserted into the patient's body to allow a medical device to be inserted through the introducer sheath into the patient's body. In order for the introducer sheath to be removable from the patient, it can be separated along its length in a longitudinal direction. The introducer sheath further comprises at least a first handle which is pivotable about a fulcrum. The first handle has a first end portion and a free second end portion so as to form a lever, such that pivoting the handle about the fulcrum causes a contacting portion of the handle to act on a respective counter portion that is operatively connected to the distal portion of the tubular body. This creates a breaking force that causes the distal portion of the tubular body to break.
