| 20120067820 | METHOD AND APPARATUS FOR DYNAMIC, VARIABLE-PRESSURE, CUSTOMIZABLE, MEMBRANE-BASED WATER TREATMENT FOR USE IN IMPROVED HYDROCARBON RECOVERY OPERATIONS - A method for treating seawater that includes the step of intaking water into at least one treatment block, wherein the treatment block includes a membrane pressure vessel having at least one membrane element, wherein the treatment block is configured such that the intake water is fed through the at least one membrane element of the membrane pressure vessel, is disclosed. The disclosed method further includes the steps of feeding the intake water through the membrane pressure vessel at a custom pressure based on the at least one membrane element of the membrane pressure vessel, and separating the intake water into at least an aqueous permeate stream and a concentrate reject stream; and outputting the aqueous permeate stream and the concentrate reject stream. | 03-22-2012 |

| 20090118637 | METHODS FOR MEASURING CROSS-SECTIONAL AREAS AND PRESSURE GRADIENTS IN LUMINAL ORGANS - The present disclosure comprises a system, catheter and method for measuring the cross-sectional areas and pressure gradients in any hollow organ, such as, for example, blood vessels. One embodiment of such a method includes the steps of introducing an impedance catheter into a treatment site, providing electrical current flow to the treatment site, injecting a first solution and measuring a first conductance value, injecting a second solution and measuring a second conductance value, and calculating the cross-sectional area of the treatment site, in part, based on the first and second conductance values. | 05-07-2009 |

| 20090187101 | METHOD AND APPARATUS TO REMOVE SUBSTANCES FROM VESSELS OF THE HEART AND OTHER PARTS OF THE BODY TO MINIMIZE OR AVOID RENAL OR OTHER HARM OR DYSFUNCTION - To accomplish isolation and removal of a substance from a vasculature, a catheter is employed to occlude a vessel of the vasculature. The substance is thus isolated in the vasculature and can be removed. In this way, the substance is removed before entering other parts of the circulatory system. This method is applicable to removal of contrast from the coronary sinus shortly after injection of the coronary arteries with the contrast. The method substantially minimizes or avoids renal dysfunction caused by angiographic procedures in which contrast must be injected. Such angiographic procedures are often performed during intervention procedures. This method substantially prevents circulation of the contrast to the kidneys where it could otherwise cause renal dysfunction or failure. The apparatus for implementation of the method is also disclosed. | 07-23-2009 |
