Abstract:
A system for assisting a patient's heart has a pump, an oxygenator, a holder having a pump receiving portion for removably receiving the pump and an oxygenator receiving portion for removably receiving the oxygenator, and a harness configured to surround at least a portion of a patient's torso. The holder is connected to the harness. The system further has a brace connected to at least a portion of the harness. The brace is configured to extend behind a back portion of a user's head and to support tubing connected to at least one of the pump and the oxygenator. A priming tray and wet-to-wet connector connecting the cardiac assist system to the cannula are also disclosed.
Abstract:
Für ein extrakorporales Life-Support-System wird eine Anordnung mit einer Saugleitung, die eine venöse Kanüle aufweist, und einer Druckleitung, die eine arterielle Kanüle aufweist, vorgeschlagen. Darüber hinaus hat die Anordnung eine Pumpe, die zwischen Saugleitung und Druckleitung angeordnet ist. Diese Anordnung zeichnet sich durch eine Entlastungsleitung mit einer Entlastungskanüle aus, wobei die Entlastungskanüle länger ist als die arterielle Kanüle und wobei die Entlastungsleitung mit der Saugleitung oder der Druckleitung verbunden ist.
Abstract:
The invention relates to actuators based on electroactive polymeric materials for use in pumping fluids or in other applications where a contractile actuation is required, in particular although not necessarily exclusively for use in vascular pulsation devices such as a variable aortic tension device. Embodiments disclosed include an actuator ( 10) comprising: an inner tubular structure (15, 12); an outer tubular structure (13, 14) surrounding the inner tubular structure ( 5, 12) and comprising a plurality of layers of a dielectric elastomeric material ( 13) and a tubular elastic support structure ( 14), the elastic support structure (14) configured to maintain a pre-stress in the layers of the dielectric elastomeric material (13), wherein the outer tubular structure (13, 14) is configured to contract in a radial direction around the inner tubular structure (12, 15) upon application of an actuation voltage signal across the dielectric elastomeric material layers (13).
Abstract:
The invention relates to a blood pump made of titanium with a measuring device for determining a flow based on acoustic flow measurement methods, and a blood pump with a temperature sensor and/or a pressure sensor, and a system with a blood pump and an inlet cannula and/or an outlet connector and a method for producing a blood pump with a measuring device.
Abstract:
A remodelable encasement structure comprising a pouch formed from at least one sheet of bioremodelable material, the pouch including an internal region and at least one lead conduit, the internal region being configured to receive a device therein, the lead conduit being configures to receive at least one device lead therein, the bioremodelable material comprising an extracellular matrix (ECM) composition that includes an ECM component derived from a mammalian source.
Abstract:
A blood clot removal device for removing blood clots from the vascular system of a patient is implantable in the patient's body. The blood clot removal device comprises a blood flow passageway, a filter provided in the blood flow passageway for filtering blood clots, and a cleaning device for cleaning the filter. By means of such blood clot removal device and system, the risk of blood clots reaching sensitive areas of the patient's body, such as the brain, is reduced.
Abstract:
A blood clot removal device for removing blood clots from the vascular system of a patient is implantable in the patient's body. The blood clot removal device comprises a blood flow passageway to be connected to the patient's vascular system to allow circulation of the patient's blood through the blood flow passageway, a filter provided in the blood flow passageway for collecting blood clots occurring in the blood flowing through the blood flow passageway, and a cleaning device for moving blood clots collected by the filter out of the blood flow passageway. By means of such blood clot removal device, the risk of blood clots reaching sensitive areas of the patient's body, such as the brain, is reduced.
Abstract:
A peristaltic pumping apparatus for use in blood processing procedures, comprising: a pump rotor rotatable about a rotational axis and a pump raceway circumferentially spaced about the axis; a pump cap disposed atop the pump rotor, the pump cap having a finger configured to engage a tubing loop of a length of tubing at a time of loading the tubing and guide the tubing loop within the raceway along the length of the tubing loop; and wherein the pump cap further comprises a tensioning wail disposed laterally opposite the finger, the tensioning wall configured to engage a length of the tubing loop at a time of unloading the tubing and provide tension to the tubing length as the tubing loop exits the raceway.
Abstract:
A ventricular assist device includes a stent for placement within a cardiac artery and arranged for placement, the stent arranged to have an open configuration defining a flow path, a rotor sized to fit within the stent and arranged for percutaneous placement the flow path, the rotor including a surface disposed about a central portion and angled with respect to the flow path and having a first plurality of magnets. A collar is sized for placement about the cardiac artery and includes a stator. A power source is coupled to the stator, and the stator and the rotor are arranged to rotate the rotor about an axis. A timing control module controls a rotational speed of the rotor. Accordingly, the surface of the rotor is arranged to move blood along the flow path in response to rotation of the rotor.
