20150245908 | DEVICES FOR REDUCING LEFT ATRIAL PRESSURE, AND METHODS OF MAKING AND USING SAME - A device for regulating blood pressure between a patient's left atrium and right atrium comprises an hourglass-shaped stent comprising a neck region and first and second flared end regions, the neck region disposed between the first and second end regions and configured to engage the fossa ovalis of the patient's atrial septum; and a one-way tissue valve coupled to the first flared end region and configured to shunt blood from the left atrium to the right atrium when blood pressure in the left atrium exceeds blood pressure in the right atrium. The inventive devices may reduce left atrial pressure and left ventricular end diastolic pressure, and may increase cardiac output, increase ejection fraction, relieve pulmonary congestion, and lower pulmonary artery pressure, among other benefits. The inventive devices may be used, for example, to treat subjects having heart failure, pulmonary congestion, or myocardial infarction, among other pathologies. | 09-03-2015 |
20140350565 | APPARATUS AND METHODS FOR DELIVERING DEVICES FOR REDUCING LEFT ATRIAL PRESSURE - A device for regulating blood pressure between a patient's left atrium and right atrium, and apparatus for delivery the device, are provided. The delivery apparatus may include one or more latching legs, a release ring, a pull chord, and a catheter wherein the latching legs are configured to engage the device for delivery. The inventive devices may reduce left atrial pressure and left ventricular end diastolic pressure, and may increase cardiac output, increase ejection fraction, relieve pulmonary congestion, and lower pulmonary artery pressure, among other benefits. The inventive devices may be used, for example, to treat subjects having heart failure, pulmonary congestion, or myocardial infarction, among other pathologies. | 11-27-2014 |
20140213959 | DEVICE AND METHOD FOR REGULATING PRESSURE IN A HEART CHAMBER - A device for regulating blood pressure in a heart chamber is provided. The device includes a shunt positionable within a septum of the heart. The shunt is designed for enabling blood flow between a left heart chamber and a right heart chamber, wherein the flow rate capacity of the device is mostly a function of pressure in the left heart chamber. | 07-31-2014 |
20140163449 | DEVICE AND METHOD FOR CONTROLLING IN-VIVO PRESSURE - 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. | 06-12-2014 |
20140128796 | METHODS AND APPARATUS FOR REDUCING LOCALIZED CIRCULATORY SYSTEM PRESSURE - 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. | 05-08-2014 |
20140128795 | METHODS AND APPARATUS FOR REDUCING LOCALIZED CIRCULATORY SYSTEM PRESSURE - 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. | 05-08-2014 |
20130197423 | METHODS AND APPARATUS FOR REDUCING LOCALIZED CIRCULATORY SYSTEM PRESSURE - 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. | 08-01-2013 |
