    摘要: Devices and methods for improving cardiac efficiency involve measuring, patient-internally, an oxygen saturation parameter indicative of oxygen usage of myocardial tissue of the heart. A cardiac electrical therapy is adjusted to cause a change of the measured oxygen saturation parameter, and the adjusted cardiac electrical therapy is selected for delivery based on a changed oxygen saturation parameter indicative of an increase in cardiac efficiency.

    摘要: Pacing left and right ventricles of the heart for delivery of heart failure therapy involves measuring right ventricular (RV) pressure and a left ventricular (LV) pressure, and computing a parameter developed from one or both of the RV and LV pressure measurements. The parameter is indicative of a degree of left and right ventricular synchronization. At least one parameter of a heart failure pacing therapy is adjusted based on the parameter to improve synchronization of the right and left ventricles.

    摘要: A guiding catheter for use in medical procedures includes a flexible shaft with one or more audio transducers and a distal tip. An audio signal may be sent to one or more of the transducers and a reflected signal is received at one or more transducers. The reflected signal is used to detect the presence of an anatomical structure to assist in navigating the catheter to its destination. In another arrangement, the transducer can be used passively to detect physical characteristics of the heart such as sound, subsonic energy or temperature, that indicate relative proximity of a destination vessel.

    摘要: Various aspects relate to a device. Various device embodiments include at least a first and a second transducer, and a controller. The first transducer is adapted to be positioned to direct a first energy wave toward a neural target, and the second transducer is adapted to be positioned to direct a second energy wave toward the neural target. The controller is connected to the transducers to generate the first energy wave with a first predetermined phase and a first predetermined amplitude from the first transducer and to generate the second energy wave with a second predetermined phase and a second predetermined amplitude from the second transducer. The amplitudes are selected so that a neural stimulation threshold is reached only during constructive wave interference. The phases are selected so that the first and second energy waves constructively interfere at the neural target. Other aspects and embodiments are provided herein.

    摘要: A method of optimizing inter-site delay is disclosed for a cardiac rhythm management device that includes a dual chamber pacemaker, especially designed for treating congestive heart failure by pacing a plurality of sites. A microcontroller is operative to adjust the pacing mode and inter-site delay of the pacemaker so as to achieve optimum hemodynamic performance. Atrial cycle lengths measured during transient (immediate) time intervals following a change in the mode inter-site delay are signal processed and a determination can then be made as to which particular configuration yields the optimum performance. Performance is optimized when the patient is at rest and when the patient exercises so that a rate-adapted dynamic value of the optimum performance can be applied.

    摘要: A body implantable system employs a lead system having at least one electrode and at least one pressure transducer at a distal end. The lead system is implanted within a patient's heart in a coronary vein of the left ventricle. The lead system includes an occlusion device at a distal end to occlude flow in the coronary vein. The pressure transducer is attached to a catheter that is disposed within an open lumen of the lead system. The pressure transducer senses a coronary vein pressure, the coronary vein pressure being proportional to the left ventricular pressure. The sensed coronary vein pressure gives indications of hemodynamic state of the left ventricle, and measured coronary vein pressure can be used to change a signal sent to the electrode to adaptively pace the patient's heart. The body implantable system can further utilize a right ventricular pressure measurement in concert with the left ventricular pressure measurement to modify pacing therapy parameters.
