20100094370 | METHODS AND APPARATUS TO STIMULATE HEART ATRIA - 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. | 04-15-2010 |
20100125288 | METHOD AND APPARATUS FOR REDUCING RENAL BLOOD PRESSURE - A method and apparatus for treatment of chronic renal failure by reducing renal perfusion pressure. Treatment is performed by partial occlusion of renal artery. A device to constrict the renal artery may be implanted in the body of a patient and include a renal pressure sensor and a mechanical control applied the renal artery to adjustably constrict a cross sectional area of the artery. | 05-20-2010 |
20100204677 | Patient hydration system and method - A fluid management system for a patient includes a console for mounting on an IV pole. The console includes an input for setting a desired fluid balance for a set therapy duration. A weighing subsystem weighs the patient's urine output collected in a urine collection chamber and weighs a source of hydration fluid. An infusion pump is integrated with the console and is configured to pump hydration fluid from the source of hydration fluid into the patient. A controller in the console is responsive to the set desired fluid balance, the set therapy duration, and the weighing subsystem. The controller is configured to determine the patient's urine output based on the weight of the urine collection chamber, determine the amount of fluid infused into the patient, and control the infusion pump to inject hydration fluid into the patient based on the set desired fluid balance, the weight of the urine collection chamber, and the weight of the source of hydration fluid to achieve the desired fluid balance during the set therapy duration. | 08-12-2010 |
20110172731 | METHODS AND APPARATUS TO STIMULATE HEART ATRIA - 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.

20120259308 | Goal-directed fluid therapy - 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. | 10-11-2012 |
20120259309 | Kidney protection method - 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. | 10-11-2012 |
