摘要： The invention relates to a pump-inflow-cannula (1) providing a blood conduit from a heart (2) and / or from an associated vessel to an external blood handling system, said pump-inflow-cannula (1) comprising a body (3), encompassing an inflow-lumen (4), extending essentially axially along a center-line (5), having a distal-end (6) for an attachment of the inflow-lumen (4) to said blood handling system, and having a proximal-end (7) for an introduction of blood from the heart (2) and / or from the associated vessel into the inflow-lumen (4). At the proximal-end (7) at least one angled-hole (8), extending around a longitudinal hole-axis (9) is provided, and said hole-axis (9) includes a presettable hole-angle (α) with the center-line (5) of the inflow-lumen (4), wherein said body (3) of the pump-inflow-cannula (1) comprises a reinforcement-means (10). The invention is also related to a pump-outflow-cannula (23) and to a blood managing system comprising a pump-inflow-cannula (1) and a pump-outflow-cannula (23) in accordance with the present invention.

摘要： The present invention involves a dynamic brake for use in a peristaltic (i.e., roller) pump. The dynamic brake avoids backlash, due to counter rotation. In addition, it does not preclude the option of hand operating the roller pump. This is achieved by initiating the braking operation after the roller pump set-point has been set to zero and only after the roller pump has decelerated below a predefined speed (e.g., 20 rpm). In addition, the braking operation is activated for only a very brief period of time (i.e., a period of time required for the pressure in the roller pump fluid conduit to subside).

摘要： The invention relates to a device for connection of a cannula made from a flexible material to a tube. The aim of the invention is to provide a device for the connection of a cannula made from a flexible material to tubes, with which uncomplicated, rapid, secure and reproducible conditions for connection and disconnection are obtained, in particular under the conditions of an operative intervention for the connection of a heart-supporting or heart-replacement blood pump. Said aim is achieved by means of a device for the connection of a cannula made from a flexible material to a tube, whereby a tube spigot (4), fixed to the tube (5), is inserted in the cannula (7), characterised in that a claw ring (1), arranged on a cannula end (71), which may be displaced as far as a stop (2, 62), may be connected to and rotated with a locking ring (3), by means of axial displacement and clipping to the locking ring (3). Said connection may be undone again by means of rotating the claw ring (1) and axially withdrawing the claw ring (1) and the cannula (7).

摘要： An implantation regime for a ventricular assist device (VAD) comprising implanting a first VAD (13) intended for short term use for a predetermined period of time and then determining whether the heart can operate without further assistance after this period of time. A second VAD (30) intended for long term use may then be implanted if necessary. Also disclosed are percutaneous leads (40) that have surface treatments (45, 47) to enable tissue ingrowth in certain areas and prevent tissue ingrowth in other areas, and an embolisation device (21, 22) carrying a coagulating material (27) for sealing an implanted cannula (15, 16) between the use of the first and second VADs.

The blood pump (316) is connected to the transseptal cannula (12). The system includes a perfusion cannula (100) adapted to be inserted percutaneously in the femoral artery for returning oxygenated blood to the atrial system of the patient. The perfusion cannula (100) is connected to the blood pump (316). A method for assisting blood flow by a patient's heart.

摘要： A turbo blood pump includes a housing 1, an impeller 5 rotatably disposed in a pumping chamber 2, bearings 9 and 10 for rotatably supporting the impeller, a rotor 13 provided outside the housing and rotationally driven by a motor, driven magnets 12 mounted on the impeller, and driving magnets 16 mounted on the rotor. The driven magnets and the driving magnets face each other via a wall of the housing to form magnetic coupling. The driven magnets and the driving magnets are arranged so that a direction of the magnetic coupling inclines with respect to a rotation axis of the impeller. The pump ensures sufficiently strong magnetic coupling between an impeller and a rotor and effects reduced load on a lower bearing supporting the impeller and little risk of hemolysis and blood stagnation.

摘要： A catheter system and devices for achieving total cardiopulmonary bypass during heart surgery are provided. The venous perfusion catheter has first and second balloons occluding the inferior and superior vena cava thereby precluding blood flow into the right atrium. An arterial perfusion catheter is inserted, advanced and positioned in the ascending aorta cephalid of the junction of the coronary arteries with the aortic root. A second flexible arterial cannula is mounted in sliding relationship with the first flexible cannula and carries an inflatable balloon adjacent its distal end to provide for occlusion of the ascending aorta. A first flexible cannula has a first lumen and an arterial venting orifice communicating with the first lumen defining a single flow path for the passage of cardioplegia solution to arrest the heart or for the evacuation of blood from the aortic root. A third lumen extends axially through the first flexible arterial cannula and communicates with a multiplicity of openings in the distal tip for suctioning blood from the left ventricle. The second flexible cannula of the arterial perfusion catheter has a first cavity extending axially therethrough that communicates with an opening at its distal tip to permit the passage of blood delivered by the cardiopulmonary bypass pump into arterial circulation. Both the venous and arterial perfusion catheters have a plurality of radially and oppositely spaced steering lumens and a plurality of steering cables fixed to the distal ends to achieve omnidirectional articulation.
