The present invention involves new interventional methods and devices for reconfiguring a portion of the gastrointestinal tract. The procedures are generally performed laparoscopically and may generally be described as laparoscopic plication gastroplasty (LPG) in which, after obtaining abdominal access, spaced apart sites on a gastric wall are engaged, approximated and fastened to create one or more tissue folds forming one or more plications projecting into the gastrointestinal space. The serosal tissue may optionally be treated during the procedure to promote the formation of a strong serosa-to-serosa bond that ensures the long-term stability of the tissue plication. These procedures are preferably carried out entirely extragastrically (i.e. without penetrating through the gastrointestinal wall), thereby minimizing the risks of serious complications.

Systems and methods are described for scoring consumers' credit risk by determining consumers' income risk and future ability to pay. Methods are provided for measuring consumers' income risk by analyzing consumers' income loss risk, income reduction risk, probability of continuance of income, and economy's impact on consumers' income. In one embodiment, a method is provided to evaluate an individual's creditworthiness using income risk based credit score thereby providing creditors, lenders, marketers, and companies with deeper, new insights into consumer's credit risk and repayment potential. By predicting consumers' income risk and the associated creditworthiness the present invention increases the accuracy and reliability of consumers' credit risk assessments, results in more predictive and precise consumer credit scoring, and offers a new method of rendering a forward-looking appraisal of an individual's ability to repay a debt or the ability to pay for products and services.

A method for treating congestive heart failure (CHF) has been developed that restores kidney renal functions by artificial vasodilation of at least one kidney. A vasodilator drug is locally delivered to the kidney via a kidney perfusion catheter. The drug can be mixed with the patient's blood, saline or other suitable solvent and the mixture directly applied to the kidney through the catheter. The restoration of kidney function assists the heart by removing excess fluid, urine and toxin from the patient, and by normalizing the patient's renin-angiotensin system and other neurohormonal substances. The method is applicable to treat chronic and acute CHF.

The present invention involves new interventional methods and devices for reducing gastric volume, and thereby treating obesity. The procedures are generally performed laparoscopically and may generally be described as laparoscopic plication gastroplasty (LPG) in which, after obtaining abdominal access, spaced apart sites on a gastric wall are engaged and approximated to create one or more tissue folds that are then secured by placing one or more tissue fasteners to produce one or more plications projecting into the gastrointestinal space. The serosal tissue may optionally be treated during the procedure to promote the formation of a strong serosa-to-serosa bond that ensures the long-term stability of the tissue plication. These procedures are preferably carried out entirely extragastrically (i.e. without penetrating through the gastrointestinal wall), thereby minimizing the risks of serious complications. Minimally invasive devices for approximating and fastening soft tissues are disclosed that enable these new interventional methods to be carried out safely, efficiently and quickly. Methods for reversing the procedure are also disclosed.

Multi-phase RF ablation employing a two-dimensional or three-dimensional electrode array produces a multitude of currents paths on the surface of the ablation zone. This results in a uniform lesion with a size defined by the span of the electrode array. An orthogonal electrode catheter array suitable for cardiac ablation is used in conjunction with a two-phase RF power source to produce uniform square-shaped lesions of size 1.2 cm². Lesions of larger size are created by successive adjacent placement of the square-shaped lesions. A temperature sensor at the electrode tip allows monitoring of ablation temperature and regulation of thereof to minimize the electrode tips from being fouled by coagulum. In another embodiment, an external auxiliary electrode is used in combination with the catheter electrodes. This also produces lesions of greater depth. In yet another embodiment, ablation is performed with a sequence of elementary electrode-electrical configurations.

A method for the controlled delivery of a fracturing fluid to a well bore comprises formulating an aqueous base fluid such that it meets or exhibits desired physical and chemical characteristics for an optimal fracturing fluid. The formulation of the aqueous base fluid max involve commingling one or more sources of waste water with a source of fresh water followed by controlled injection of one or more additives. This process is substantially completed prior to delivering the aqueous base fluid to the well site. This allows the delivery of an optimal volume of the aqueous base fluid with homogeneously blended additives to the well bore.

A novel plate fin heat exchanger adapted for high and low velocity fluid flows for dissipating heat from a heat generating component. The heat exchanger comprises an array of fins being affixed to and in thermal communication with a thermally conductive base, wherein the fins are arranged in a fan tail configuration for minimizing flow bypass, and further providing reduced thermal resistance for fluid passing through the fin field. The fins are affixed to and in thermal communication with the base at an acute angle, such that the effective width of the array of fins exceeds the width of the base. The enlarged effective width of the fin array in comparison to conventional heat exchanger provides an increased volume for fluid flow, thereby allowing a greater volume of fluid to enter the fin field and a greater surface area of plate fins for cooling the fluid passing through the heat exchanger. In addition, the heat exchanger comprises a fin density of at least ten fins per inch or greater of base length thereby providing a narrow channel heat exchanger with a fan tail. The aspect ratio of the individual channels between the fins, as compared to parallel fins affixed perpendicular to the base through an extrusion method, generates a reduced pressure drop across the heat exchanger. Accordingly, the heat exchanger of the present invention expands the envelope of cooling performance provided by fluid flow over an array of thermally conductive plates.
