  • Patent number: 9149638
    Abstract: A method of controlling pulmonary capillary pressure is disclosed which includes increasing the output of a first ventricle (V1) (e.g., a left ventricle) relative to second ventricle (e.g., right ventricle) by increasing the magnitude of a post extrasystolic potentiation (PESP) therapy effect in the first ventricle relative to the magnitude of a PESP therapy effect produced in the second ventricle. In certain embodiments of the invention, this may be accomplished by adjusting the extra-stimulus interval (ESI) in either or both of the left ventricle and the right ventricle, for example.

  • Publication number: 20150272655
    Abstract: A system and method for preventing unintended tissue damage from the delivery of unintended bipolar radiofrequency energy. The system may include a multi-electrode ablation device and an RF delivery unit. The RF delivery unit may transmit unipolar energy to the plurality of electrodes, the energy being in phase, with all electrodes delivering the same voltage and being activated at the same time to deliver no bipolar energy. Additionally or alternatively, the RF delivery unit may transmit bipolar energy to the electrodes. Here, voltage differences between each pair of adjacent electrodes may be monitored and the level of bipolar energy being delivered may be calculated. The voltage of energy delivered to at least one electrode in each adjacent electrode pair may be adjusted if the amount of delivered bipolar energy exceeds a safety threshold.

  • Patent number: 9144685
    Abstract: An apparatus and method to discriminate cardiac events by sensing atrial and ventricular depolarizations having associated refractory periods thereafter. A fast ventricular rate is detected in response to the sensed ventricular depolarizations. Responsive to detecting the fast ventricular rate, at least one stimulus pulse is delivered to atrial tissue within the associated refractory period of the ventricle but outside of an associated refractory period of the stimulated atrial tissue. A ventricular response to the atrial tissue stimulus pulse is determined, and the cardiac event is discriminated based on the ventricular response to the atrial tissue stimulus pulse.
