摘要： Detection and treatment of disordered breathing, with treatment being primarily delivered using electrical stimulation of the diaphragm, either directly or by stimulating appropriate nerves. In some embodiments, the stimulus is applied to still at least one lung upon detection of an apnea-hypopnea of some length or upon the detection of hyperpnea. The stimulation may be initiated during the apnea-hypopnea period or upon detection of a breath of a predetermined intensity near the end of apnea-hypopnea. The stimulation may be initiated in phase with respiration or irrespective of the phase of respiration.

摘要： 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.

摘要： A method and apparatus for treatment of hypertension and heart failure by increasing vagal tone and secretion of endogenous atrial hormones by excitory pacing of the heart atria. Atrial pacing is done during the ventricular refractory period resulting in atrial contraction against closed AV valves, and atrial contraction rate that is higher than the ventricular contraction rate. Pacing results in the increased atrial wall stress. An implantable device is used to monitor ECG and pace the atria in a nonphysiologic manner.

摘要： A method of driving a toxin through a patient's kidneys, the method includes administering a diuretic to the patient to induce increased urine flow and collecting urine expelled by the patient. The amount of urine expelled by the patient is determined based on the collected urine. The patient is infused with fluid from a fluid source. Diuresis is induced by automatically adjusting the amount of fluid infused into the patient from the fluid source based on the determined amount of urine expelled by the patient to at least balance the amount of urine expelled by the patient with the amount of fluid infused into the patient to drive the toxin out of the patient's kidneys.

摘要： A method includes setting a hydration goal and administering a diuretic to the patient to induce increased urine flow and collecting urine expelled by the patient. The amount of urine expelled by the patient is determined based on the collected urine. The patient is infused with fluid from a fluid source. The amount of fluid infused into the patient is determined. Diuresis is induced by automatically and continuously adjusting the amount of fluid infused into the patient from the fluid source to meet the hydration goal based on the set hydration goal, the determined amount of urine expelled by the patient and the fluid infused.
