    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 stabilizing 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： Devices, systems and methods for treating disorders characterized by low cardiac output. The devices, systems and methods use intra-aortic balloon counterpulsation in combination with hypothermia of all or a portion of a human or veterinary patient's body to improve coronary perfusion and cardiac output. To effect the hypothermia, a heat exchange catheter may be positioned in the a patient's vasculature separately from the intra-aortic balloon counterpulsation catheter. Alternatively, a combination Intra-aortic balloon counterpulsation/heat exchange catheter may be utilized. Such combination catheter comprises a) a catheter sized for insertion into the aorta, b) a counterpulsation balloon and c) a heat exchanger. A drive/control system receives temperature and electrocardiograph signals and drives the inflation/deflation of the counterpulsation balloon as well as the heating/cooling of the heat exchanger.

    摘要： A system includes a sensor and a processor. The sensor is configured to generate hemodynamic information for a patient. The processor is configured to execute instructions to calculate spectral content using the hemodynamic information. The processor is configured to generate an output signal based on the calculated spectral content. The calculated spectral content includes a fundamental component and at least one harmonic component. The spectral content corresponds to at least one of amplitude and frequency. The output signal corresponds to a state of the patient or corresponds to an operational parameter of a cardiac assist device associated with the patient.

    摘要： A dual-balloon cardiac pump comprises a flexible catheter tube in pneumatic communication with inflatable ventricular and aortic balloons, which are inflated and deflated in accordance with a programmed sequence of pressurized inert gas into the catheter tube as regulated by a control unit. The programmed sequence rapidly inflates and deflates the ventricular balloon after left ventricular contraction is completed. The programmed sequence inflates the aortic balloon after the aortic valve closes and deflates it just before the next systolic cycle begins.
