    摘要: A method and apparatus for prevention and reduction of myocardial infarct expansion and heart remodeling by infusion of fluid into the pericardial space of the heart to created a hydraulic heart constraint. As a result of the constraint ventricular stress and dilation is reduced. Pressure in the pericardial sac is maintained at a safe level for the duration of treatment. Apparatus consists of a catheter and a fluid infusion system.

    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 patient hydration system including an infusion device for administering hydration fluid to a patient, and a hydration fluid measurement device responsive to a source of hydration fluid, a patient urine output measurement device. A controller is responsive to the hydration fluid measurement device and the patient urine output measurement device. The controller operates the infusion device, in response to the patient urine output measurement device and the hydration fluid measurement device, to hydrate the patient based on the patient's urine output. The controller also monitors the operation history of the infusion device thereby providing redundancy in the measurement of the amount of hydration fluid administered to the patient.

    摘要: A method and apparatus for treatment of hypertension and heart failure by increasing secretion of endogenous atrial hormones by pacing of the heart atria. Atrial 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.

    摘要: Blood flow restrictors are discussed. In some examples, a restrictor apparatus includes a converging entry portion, a diverging exit portion, and optionally a narrowed portion therebetween to restrict the flow of blood through an arteriovenous graft from a subject's artery to a vein. The structure of the restrictor apparatus decreases the pressure and volume of blood flow between the artery and vein to reduce or prevent hyperplasia or stenosis on the venous side, an increased load on the heart, or blood steal, among other things. The restrictor apparatus can be separate from, but couplable to, the arteriovenous graft. The restrictor apparatus can be integral with the arteriovenous graft. In some examples, the restrictor apparatus can be inserted into the arteriovenous graft in a compressed size and shape, and subsequently be allowed to expand to an uncompressed size and shape. Methods of forming and using the restrictor apparatus are also discussed.

    摘要: A method and apparatus to slow a heart rate with subthreshold electric stimulation of the SA node. Stimulation is applied at a specific time in the cardiac cycle and at a specific subthreshold level. To control the heart rate, the stimulating signal may be modified automatically based on physiologic feedbacks. Stimulation may be applied using an implantable pulse generator directly to the SA node of the heart.
