  • Publication number: 20230347146
    Abstract: A system for treating disordered breathing of a human being includes an implantable transvenous stimulation lead having at least one stimulation electrode and a sensor configured to detect activity level of the human being. The system includes an energy source, a pulse generator and circuitry, the circuitry operative to receive a signal indicative of the activity level of the human being from the sensor, wherein the circuitry is configured to cause the energy source and the pulse generator to deliver spaced apart stimulation signals to the at least one stimulation electrode while the activity level of the human being is sufficiently low to be indicative of sleep. Spaced apart stimulation pulses from the electrode are configured to extend a duration of a time of at least one breath being defined as the time from an onset of inhalation to the onset of inhalation of a successive breath.

  • Patent number: 11801092
    Abstract: Apparatuses and methods for treating a heart failure patient by ablating a nerve of the thoracic splanchnic sympathetic nervous system to increase venous capacitance and reduce pulmonary blood pressure. A method comprising: inserting a catheter into a vein adjacent the nerve, applying stimulation energy and observing hemodynamic effects, applying ablation energy and observing hemodynamic effects, applying simulation energy after the ablation and observing hemodynamic effects and monitoring for presence of the lung in the ablation zone. An alternative method comprising: inserting a catheter into a vein adjacent the nerve, detecting that lung tissue is a safe distance from an ablation zone, and delivering ablation energy to the target nerve when lung tissue is a safe distance from the ablation zone.

  • Patent number: 11759639
    Abstract: A method and apparatus for treatment of hypertension and heart failure by increasing secretion of endogenous atrial hormones by pacing of the heart. Pacing is done during the ventricular refractory period resulting in premature atrial contraction that does not result in ventricular contraction. Pacing results in the atrial wall stress, peripheral vasodilation, ANP secretion. Concomitant reduction of the heart rate is monitored and controlled as needed with backup pacing.

  • Publication number: 20230233817
    Abstract: A method and apparatus for treatment of heart failure by increasing secretion of endogenous naturetic hormones ANP and BNP such as by stimulation of the heart atria. Heart pacing is done at an atrial contraction rate that is increased and can be higher than the ventricular contraction rate. Pacing may include mechanical distension of the right atrial appendage. An implantable device is used to periodically cyclically stretch the walls of the appendage with an implanted balloon.

  • Patent number: 11696985
    Abstract: A fluid therapy method for an ADHF patient includes setting a urine output rate desired threshold, setting one or more desired negative net gain rates, and optionally setting a total fluid loss goal. The urine output of the patient is monitored and fluid is automatically administered to the patient at increasing rates to equal to or approximately match the patient's increasing urine output rates until the patient's urine output rate reaches the set urine output rate desired threshold. Thereafter, fluid is administered to the patient at rates to achieve the set desired negative net gain rate until the fluid loss goal is reached. Thereafter, until the end of therapy, fluid is administered to the patient at rates equal to or approximately equal to the monitored urine output rates.
