  • Patent number: 7335192
    Abstract: Methods and apparatus are provided for treating congestive heart by actively or passively enhancing perfusion to the renal arteries. A first embodiment comprises a specially configured balloon catheter and extracorporeal pump, wherein the pump operates in a “once-through” fashion or alternating volume displacement mode. In another embodiment the catheter includes a pair of balloons to isolate a region of the aorta, and a third balloon that directs flow into the renal arteries. In still further embodiments, a stent or cuff having a constricted region is deployed in or around the aorta, respectively, to create a backpressure upstream of the stent or cuff. Methods of enhancing renal perfusion also are provided.

  • Publication number: 20070282157
    Abstract: A differential pressure regulating device is provided for controlling in-vivo pressure in a body, and in particularly in a heart. The device may include a shunt being positioned between two or more lumens in a body, to enable fluids to flow between the lumens, and an adjustable flow regulation mechanism being configured to selectively cover an opening of the shunt, to regulate the flow of fluid through the shunt in relation to a pressure difference between the body lumens. In some embodiments a control mechanism coupled to the adjustable flow regulation mechanism may be provided, to remotely activate the adjustable flow regulation mechanism.

  • Publication number: 20040097900
    Abstract: Methods and apparatus are provided for treating congestive heart failure using a catheter having an inlet end configured for placement in the source of arterial blood such as the aorta, left ventricle or a femoral artery, and an outlet end having at least one conduit configured to be placed in the renal arteries. The catheter includes a lumen through which blood passes from the aorta or left ventricle directly to the renal artery, means for engaging the first conduit with renal artery. The means for engaging also may reduce backflow of blood into the abdominal aorta. The catheter preferably is configured to permit percutaneous, transluminal implantation. Methods of using and implanting the catheter are also provided.

  • Publication number: 20020198192
    Abstract: A therapeutic formulation comprises a topically acceptable semisolid vehicle and carbamazepine, the vehicle consisting of components that are compatible with the carbamazepine, and the carbamazepine being in a concentration sufficient to permit a therapeutically effective amount of the carbamazepine to be absorbed from the formulation into the skin of a patient. The vehicle may be a cream, ointment, or gel. A method of treating a skin condition of a patient such as psoriasis comprises applying carbamazepine topically to the patient's skin until the condition improves. A method of administering carbamazepine to a patient comprises applying a formulation comprising carbamazepine topically to the patient's skin.

  • Publication number: 20020173742
    Abstract: The present invention is thus directed to methods and apparatus for decreasing pressure in a first portion of a vessel of the cardiac structure of a patient by implanting a shunt communicating with an area outside said first portion, whereby a volume of blood sufficient to reduce pressure in said first portion is released. Preferably, the first portion comprises the left ventricle and the pressure reduced is the end diastolic pressure, which is accomplished by having the shunt communicate with the left ventricle so a small volume of blood is released from the left ventricle to reduce the end diastolic pressure.
