  • Patent number: 12005295
    Abstract: An exercise device includes a resistance unit having a connecting gear. It further includes a cable. It further includes an arm that routes the cable to an actuator. The arm is rotatable relative to the resistance unit about the connecting gear, the arm having a central axis. The arm includes a control that mechanically disengages a locking mechanism from the connecting gear. The control is activated by an activation force substantially directed either toward the central axis of the arm, along a length of the arm, or about the central axis. The activation force is mechanically converted into linear force along the arm that disengages the locking mechanism from the connecting gear.

  • Publication number: 20220001163
    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.

  • Patent number: 10987058
    Abstract: Systems and methods are provided for optimizing hemodynamics within a patient. Specifically, the system incorporates invasive sensor data (e.g., pressure measurements) combined with mechanisms to dynamically change the loading conditions of the heart and/or heart rate, in order to understand hemodynamic parameters. Computational analyses on dynamic sensor data are used to understand and guide heart rate, filling pressures, and/or volume resuscitation in critically ill patients. By pacing the heart or inducing tricuspid regurgitation, the system may cause dynamic changes in sensor data to understand optimal loading conditions and heart rates. While determining optimal hemodynamic parameters, the system may then automatically optimize the heart rate and/or filling pressures in critically ill patients.
