Abstract: One or more techniques and/or systems are disclosed for a fluid inlet that mitigates uptake of undesired debris into fluid transport system. A fluid inlet can direct fluid toward one or more fluid inlets, and debris entrained in the fluid may bypass the fluid inlet(s). The fluid inlet can be used to mitigate uptake of debris into a fluid transport system, when placed in the path of fluid flow. A shape of the fluid inlet can be configured to direct fluid flow into the fluid inlet(s), while the shape allows debris entrained in the fluid to flow past the fluid inlet(s).

Abstract: One or more techniques and/or systems are disclosed for a valve. An exemplary valve may be able to provide a more compact profile than current valves, allowing for installation in locations that have size limitations, and/or may allow for more room in areas where prior non-compact valves are installed. Such a valve may be used for fluid intake to a pressurized fluid dispensing system. A compact valve can comprise a valve actuator that is disposed in line with the fluid intake of the valve, and not offset and extending from the valve, such that the flow of fluid passes through a point of rotation of the actuator. Further, a transmission may be used to transfer user actuation input to an internal flow control component, such as a ball-type flow controller, to move the flow control between an open and closed position.

Abstract: An implantable medical device applies an electric signal to at least a portion of a heart in a subject. A resulting electric signal is collected from the heart and is used together with the applied signal for determining a cardiogenic impedance signal. The impedance signal is processed in order to estimate an isovolumetric contraction time, an isovolumetric relaxation time and an ejection time for a heart cycle. These three time parameters are employed for calculating a Tei-index of the heart. The Tei-index can be used as myocardial performance parameter in heart diagnosis and/or cardiac therapy adjustment.

Abstract: An implantable medical device comprises a connector connectable to an implantable oxygen sensor configured to generate a sensor signal representative of oxygen concentration in coronary sinus blood in a subject's heart. An ischemia detector is connected to the connector and configured to detect an ischemic event in the heart if the sensor signal indicates a temporary decrease in oxygen concentration in the coronary sinus blood below a normal level followed by a temporary increase in oxygen concentration in the coronary sinus blood above the normal level.

Abstract: An implantable medical device is connected to a multipolar LV lead and an implantable sensor. The sensor signal from the sensor is used to identify a time point of mitral valve closure for a cardiac cycle when a ventricular pulse generator generates pacing pulses that are applied to the electrodes of the multipolar LV lead according to a pacing sequence. A time interval processor determines the time interval from onset of LV activation to the time point of mitral valve closure. This procedure is repeated for multiple different pacing sequences of a sequence set. The pacing sequence that resulted in shortest time interval is then selected by a selector as the currently optimal pacing sequence for the patient.

Abstract: An implantable medical device, IMD, (100) is connectable to at least one ventricular lead (210) having a ventricular basal electrode (214) and a ventricular apical electrode (212). The IMD (100) comprises a pulse generator (120) for generating pacing pulses applied to a heart (10) through the ventricular lead (210). The operation of this pulse generator (120) is controlled by a controller (130) that is configured to control the pulse generator to first deliver a pacing pulse to the ventricular basal electrode (214) to stimulate the basal portion of the ventricle (12, 14) before a pacing pulse is delivered to the apical portion of the ventricle (12, 14) by the ventricular apical electrode (212). This pulse sequence achieves a biologically more correct cardiac stimulation and a contraction pattern that reduces the risk for valvular regurgitation.

Abstract: An implantable medical device is connectable to an epicardial left ventricular lead having at least one epicardial electrode and a myocardium penetrating catheter with at least one endocardial electrode and present in a lumen of the lead. The device comprises a pulse generator controller that controls a ventricular pulse generator to generate pulses to be applied to the epicardial and endocardial electrodes. The controller uses an endocardial-to-epicardial time interval or epicardial-to-endocardial time interval to coordinate endocardial and epicardial activation of the left ventricle to thereby achieve cardiac pacing that closely mimics the natural electrical activation pattern of a healthy heart.

Abstract: In an implantable medical device such as an implantable cardiac defibrillator, and a method for classifying arrhythmia events, IEGM signals are analyzed to detect an arrhythmia event and a respiratory pattern of the patient is sensed. At least one respiratory parameter reflecting characteristics of the respiratory pattern of the patient is determined based on the sensed respiratory pattern and a respiratory measure corresponding to a change of a rate of change of the at least one respiratory parameter is calculated. The detected arrhythmia event is classified based on the respiratory measure and the IEGM signals, wherein arrhythmia events that satisfy at least a first criterion is classified as an arrhythmia event requiring therapy.

Abstract: In an implantable heart monitoring device and method, particularly for monitoring diastolic dysfunction, a control circuit (a) detects the heart rate, (b) derives information correlated to the stroke volume of the heart at the detected heart rate, and (c) stores the detected heart rate and the derived information correlated to the stroke volume in a memory. The control circuit automatically implements (a), (b) and (c) at a number of different occasions for a number of different, naturally varying heart rates, so that the memory contains information indicating the stroke volume as a function of the heart rate.

Abstract: An ischemia detecting system has an implantable medical device connectable to an LV cardiac catheter with sensors for generating sensor signals representative of the concentration of a constituent in coronary venous blood at different sites in the coronary venous system. The sensor signals are co-processed by the system to detect an ischemic region of the subject's heart based on a relation between the sensor signals. The detection of the particular ischemic cardiac region is possible by conducting the concentration monitoring on either sides of a branching vein in the coronary venous system and co-processing the sensor signals.
