Abstract
Systems and methods are provided for optimizing hemodynamics within a patient's heart, e.g., to improve the patient's exercise capacity. In one embodiment, a system is configured to be implanted in a patient's body to monitor and/or treat the patient that includes at least one sensor configured to provide sensor data that corresponds to a blood pressure within or near the patient's heart; at least one component designed to cause dyssynchrony of the right ventricle, and a controller configured for adjusting the function of the at least one component based at least in part on sensor data from the at least one sensor.
Claims23
A system configured to be implanted in a patient's body to monitor and/or adjust electrical activation of the patient's heart, the system comprising:
- at least one sensor acquiring signals corresponding to patient activity or movement;
- at least one pacing component positioned adjacent a free wall of a right ventricle of the heart, whereby stimulation of the at least one pacing component is designed to compromise function of the right ventricle;
- and
- a controller coupled to the at least one sensor and at least one pacing component for adjusting the function of the at least one pacing component based at least in part on the signals from the at least one sensor.
A system for monitoring and/or treating a heart of a patient to increase the patient's capacity for physical activity, comprising:
- a blood pressure sensor implantable within a region of the heart;
- an adjustable component configured to affect contractility of a right ventricle of the heart;
- an activity sensor implantable within the patient's body;
- at least one pacing component sized for introduction into a region of the heart;
- and
- a processor operatively coupled to the pressure sensor, the adjustable component, the activity sensor, and the at least one pacing component to:
- acquire activity data from the activity sensor to determine a level of activity of the patient;
- acquire pressure data from the blood pressure sensor o determine blood pressure adjacent the region;
- and
- adjust the adjustable component based at least n part on the determined blood pressure.
6-10. (canceled)
A method for monitoring and/or adjusting an electrical system of a heart of a patient, the method comprising:
- acquiring signals from a sensing element within the heart indicating norm al timing of activation of a right ventricle of the heart;
- and
- delivering one or more electrical signals to a free wall of the right ventricle before activation of the right ventricle to affect function of the right ventricle.
18-19. (canceled)
A system for monitoring and/or adjusting electrical activation of a heart of a patient, the system comprising:
- an elongate member sized for introduction into a right ventricle of the heart, the elongate member carrying a sensing element;
- one or more electrodes configured for introduction into the right ventricle;
- and
- a processing unit operatively coupled to the sensing element and one or electrodes to:
- acquire signals from the sensing element to determine normal timing of activation of the right ventricle;
- and
- deliver one or more electrical signals to a free wall of the right ventricle via the one or more electrodes before activation of the right ventricle to compromise normal function of the right ventricle.
