  • Patent number: 12186568
    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 adjustable component designed to cause blood to flow in a direction opposite to the normal direction (regurgitation) within the patient's heart; and a controller configured for adjusting the function of the at least one adjustable component based at least in part on sensor data from the at least one sensor.

  • Publication number: 20240423709
    Abstract: Apparatus, systems, and methods are provided for optimizing radiation therapy to a patient to treat cardiac arrhythmias. The system generally includes an ultrasound device placed within the esophagus to image and map cardiac structures in real-time. The system may also control the ventilation of the patient to optimize ultrasound monitoring and radiation delivery. The device in the esophagus is designed to position and monitor the esophagus and/or nearby structures to optimize radiation delivery to targets while minimizing radiation to other key structures. In addition, different ablation technologies may be delivered from within the esophagus to ablate certain tissues that cannot be safely ablated with radiation therapy. Finally, the esophageal device may have electrical or magnetic properties that can be used to guide the radiation therapy.

  • Patent number: 12121731
    Abstract: Apparatus, systems, and methods are provided for optimizing intracardiac filling pressures and cardiac output in patients with heart failure, conduction disease, and atrial fibrillation. The system is able to adjust and optimize intracardiac filling pressures and cardiac output by adjusting heart rate and the effective amount of total body blood volume. The device includes an adjustable member that may create a mean pressure differential in order to manifest an effective “mechanical diuresis” by sequestering extraneous blood volume to the high-capacitance of the venous vasculature. The system is therefore designed to reduce intracardiac filling pressures while maintaining or even increasing cardiac output.

  • Patent number: 11090492
    Abstract: Apparatus, systems and methods are provided for prevention and/or remediation of cardiac arrhythmias, e.g. optimizing anti-tachycardia pacing (ATP) algorithms. More particularly, implantable devices are provided that measure and treat cardiac arrhythmias. By monitoring the ATP attempt from additional electrodes, far-field morphology analyses, and/or measuring the return interval from a failed ATP attempt; the devices may estimate when entrainment has occurred, the amount of delay within the reentrant tachycardia, and/or tachycardia termination/acceleration. These variables and occurrences can be used to optimize the first and/or subsequent ATP attempts. Furthermore, other exemplary embodiments describe methods to integrate electrical restitution properties into the design of ATP pacing algorithms to facilitate tachycardia termination.
